I've only recently started playing with the ~/.bashrc file and want more ideas to play with. Please share your bashrc file and show all of us what cool and handy things you can do with bash.

Here is my bashrc:

# don't put duplicate lines in the history. See bash(1) for more options
export HISTCONTROL=ignoredups

# set variable identifying the chroot you work in (used in the prompt below)
if [ -z "$debian_chroot" ] && [ -r /etc/debian_chroot ]; then
debian_chroot=$(cat /etc/debian_chroot)
fi

# set a fancy prompt (non-color, unless we know we "want" color)
case "$TERM" in
xterm-color)

What does the .bashrc file do actually? What's its function?

What does the .bashrc file do actually? What's its function?

It is a configuration file that is read every time that you open the terminal. As an example of its use, you can create an alias like

alias rm='rm -iv'

Now, every time you use the command rm, bash will in reality execute rm -iv which means that you will be asked to confirm any removals. You will also get an output that tells you what has been done.

What does the .bashrc file do actually? What's its function?

bash reads it as it starts (eg when you start a terminal). it lets you customise how the terminal works, and set up shortcuts

i like these handy shortcuts

alias h="history|grep "
alias f="find . |grep "
alias p="ps aux |grep "
alias o="gnome-open "

first three let you search command line history, files in current directory and subdirs, and running processes. the 'o' lets you open a file in what ever it would use if you double clicked it.

alias pc='python -ic "from __future__ import division; from math import *"'

opens python with settings that make it useful for quick calculations. (similar to bc, but i am used to python syntax. the future division but means that 1/2 = 0.5 instead of 0).

alias ps1_short="PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\W\[\033[00m\]\$ '"
alias ps1_long="PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '"

switches between shown the whole path in the prompt, and just the top bit. i like to see where i am, but sometimes it just gets too deep.

What does the .bashrc file do actually? What's its function?

It is the configuration file of bash (http://en.wikipedia.org/wiki/Bash). You can use the bashrc file to add functions or aliases to bash.

For example, in my bashrc file the "extract" section allows me to extract any archived file from the command line with the command extract, for example "extract example.tar.gz". These aliases basically tell bash to run certain applications, in this example the tar command, with certain options as specified in the bashrc file, in this case xzf.

Have a look at the bashrc files posted in this thread. Most of the aliases should make sense as they are.

You can also use the bashrc file to change your terminal header (generally "username@computer-name ~$" in Ubuntu). See here (http://ubuntuforums.org/showthread.php?t=674446) for more on that.

EDIT: Seems I was a bit slow...:-s

Well, I am a newbie (like a matter of 3 days) so I haven't gotten into much customization, however I am sure I will in time, I did so with Litestep under windows. Though, I did have to post to this, because I laughed my *** off when I read this topic. The ultimate question is though, does one get tossed a beer when one shows them?

Just backup your current bashrc before starting and you'll be fine.

browsers can't read these ascii chars but if you just download the bashrc.txt file linked in my previous post it will work.

I only mess with .bash_aliases as of yet; hopefully I'll understand and get to messing with .bashrc more in the upcoming weeks.

Either way, here are my aliases and the single function I've written thus far:

#command-line manipulation
alias new='ls -lt --color=auto | head'
alias rm='rm -v'
alias cp='cp -v'
alias mv='mv -v'

# lynx web browser
alias qcdn='lynx -term=vt100 http://www.qcdn.org/'
alias jtforum='lynx -term=vt100 http://www.z10.invisionfree.com/jammintunes'

#conky
alias smallconky='(conky -c ~/.conkyrc-minimal &)'
alias bigconky='(conky &)'
alias killconky='killall conky'

#script functions
function makescript() { touch ~/bin/"$@" && chmod ~/bin/"$@" -x && gedit ~/bin/"$@"; }

corney91

March 4th, 2008, 08:31 PM

Here's a handy one for conky:

alias conkyreset='killall -SIGUSR1 conky'
It resets conky from the config, so you don't have to go through killing and restarting after making a minor adjustment.

Tristam Green

Here's a handy one for conky:

alias conkyreset='killall -SIGUSR1 conky'
It resets conky from the config, so you don't have to go through killing and restarting after making a minor adjustment.

I imagine that I could likewise do
alias conkyreset 'killall -SIGUSR1 (conky -c ~/.conkyrc-minimal &)'
and achieve the same effect? or would a function be more suitable?

function conkyreset() { killall conky && (conky -c ~/.conkyrc-minimal &) }

corney91

March 4th, 2008, 11:26 PM

IIRC, because the process is called conky, 'killall -SIGUSR1 conky' is enough even if you use 'conky -c .conkyrc_minimal'

Tristam Green

March 5th, 2008, 03:34 AM

Cool, I didn't know what the -SIGUSR1 part did.

Thanks for that :)

I thought it was impossible to have a bash prompt as fancy as zsh's ones, but I've found a way
The whole article is here :
http://ayozone.org/2008/02/25/bash-fancy-prompt-and-improvments/
and the bashrc file (you'll have to rename it) :
http://ayozone.org/wp-content/uploads/2008/02/bashrc.txt

Great article and prompt, but i have one problem...
Its filling with blocks... here's a screenshot with the terminal open and the relevant section of my bashrc since im sure copy paste will just display wonky characters...

Also, any suggestions on getting that bad boy to work in eterm at all??? eterm apaprently REALLY doesnt like those characters
EDIT: ok, so switching from konsole to rxvt-unicode solved that issue, any reason why konsole is having trouble though???

Actually, I only tested this in gnome-terminal, a known issue is that it doesn't work with many polices (the better one is monospace).
The strange thing in your screenshot is that the char that draw the lines work every where but not in the fill.
I'll try to find a fix for that.
edit : I think it can work only in term that can use truetype fonts (eterm doesn't afaik)

Nythain

March 12th, 2008, 09:58 PM

yeah, its really odd, especially since the opening and trailing -'s display right, just not the fill one, and that it works in rxvt-unicode and gnome-terminal, but not was wonky in konsole (i tried changing from PixelCarnageMonoTT to Monospace and had the same problem) but its really cool, because it forced me to figure out how to set up rxvt-unicode to do what i want

the only reason i defaulted to Eterm to begin with was because i was more familiar with it... i like rxvt better now :)

I have my first bash custom set up.

# Sample .bashrc for SuSE Linux
# Copyright (c) SuSE GmbH Nuernberg

# There are 3 different types of shells in bash: the login shell, normal shell
# and interactive shell. Login shells read ~/.profile and interactive shells
# read ~/.bashrc; in our setup, /etc/profile sources ~/.bashrc - thus all
# settings made here will also take effect in a login shell.
#
# NOTE: It is recommended to make language settings in ~/.profile rather than
# here, since multilingual X sessions would not work properly if LANG is over-
# ridden in every subshell.

# Some applications read the EDITOR variable to determine your favourite text
# editor. So uncomment the line below and enter the editor of your choice :-)
#export EDITOR=/usr/bin/vim

@ urukrama - Great thread, I'm learning something new. :)

Here's a handy one for conky:

alias conkyreset='killall -SIGUSR1 conky'
It resets conky from the config, so you don't have to go through killing and restarting after making a minor adjustment.

Doesn't work for me. I only changed one thing:

alias kiacs='killall -SIGUSR1 conky'

meaning KilledInActionConkyStart

Conky doesn't stop or restart

bruloo@bruloo:~$ kiacs
bruloo@bruloo:~$

Normally I use:

killall conky
./.startconky

Just what is: -SIGUSR1

In layman terms please, I'm a green bean here.

But it's not doing anything that I can see.

EDIT: From file:///usr/share/doc/conky/docs.html

You Should Know

An easy way to force Conky to reload your ~/.conkyrc: "killall -SIGUSR1 conky". Saves you the trouble of having to kill and then restart.

Wherein lies my problem I think, I'm not using ~/.conkyrc

So I changed the alias I have ( conky in action):

alias cia='killall conky && ./.startconky'

To all of you using the extract script: there is a convenient package called atool that does the same. (probably more robust)

I like this thread.

Now for a question:

alias clean='rm -f "#"* "."*~ *~ *.bak *.dvi *.aux *.log'

This I have:

-f, --force
ignore nonexistent files, never prompt

These are probably like that other OS:
* = wildcard

*~ = any_file_ending_with~
*.~ = any_file_ending_with.~
*.dvi = any_file_ending_with.dvi
*.aux = any_file_ending_with.aux

What do these do:
"#"* "."*~

And last but not least.
What folder does this work in or is it the entire drive?

Thanks
Bruce

should work only on the current folder where you stand in your term.
"#"* should mean a file starting with a #
and "."*~ should mean a file with an extension (eg txt) ended with a ~

OK, that sound reasonable.

Time to create a test folder with test files and instead of:

rm -f
for test purposes ....

rm -i

Thanks ayoli

You're absolutely right except for the last one, "."*~ (or \.*~) should catch hidden backup files that start with a dot and end with tilde.

I don't have much use of that command nowadays since I have figured out how to stop nano, emacs et cetera to make backups.

rm -i

I've got

alias rm='rm -vi'

in my .bashrc. This means that the default behavior of rm is to ask for confirmation before removal. When I don't want that, I can override the -i flag by using

rm -f

Hate to be a pest, but I'm green behind the ears here.

Could you tell me "exactly" what is needed to change the prompt like you have it please?

Sure. First, you will need zsh.

sudo aptitude install zsh

Then put this into the file '~/.zshrc'

HISTFILE=~/.histfile
HISTSIZE=2000
SAVEHIST=2000

Now, load up zsh by just executing 'zsh'.

If you don't like my colors you can change it! Do sth like,

setprompt $fg[green] $fg[blue] $fg[white]

zsh also comes with a number of prompt themes. Try,

autoload promptinit
prompinit
prompt -h

If you like it you can change the shell permanently by executing 'chsh' and then enter '/bin/zsh'.

Of course zsh has tons of other features to explore! Check out http://www.acm.uiuc.edu/workshops/zsh/toc.html

I've got

alias rm='rm -vi'

in my .bashrc. This means that the default behavior of rm is to ask for confirmation before removal. When I don't want that, I can override the -i flag by using

rm -f

I changed the -f to -i for test purposes. It's interactive and therefore verbose. The -v isn't really needed in this case.

However -vf would do it automatically and show you what's going on at the same time. :)

Using -i

bruloo@bruloo:~$ cd test
bruloo@bruloo:~/test$ clean
rm: cannot lstat `#*': No such file or directory
rm: cannot lstat `.*~': No such file or directory
rm: remove regular file `%gconf.xml~'? y
rm: remove regular file `QStart.~'? y
rm: remove regular file `mkdev.bak'? y
rm: cannot lstat `*.dvi': No such file or directory
rm: cannot lstat `*.aux': No such file or directory
rm: cannot lstat `*.log': No such file or directory

Executing 'chsh' and changing /bin/bash to /bin/zsh didn't do it. :(

bruloo@bruloo:~$ chsh
Password:
Changing the login shell for bruloo
Enter the new value, or press ENTER for the default

hmmm ... OK, [Ctrl]+[Alt]+ maybe?

Will try that right after [Submit Reply]. :)

I'm curious, can an "alias" accept variables?
Is it hard to tell I'm green behind the ears here :?:

For example the alias m2t (man to txt)

at the prompt:

m2t chmod
it will treat "chmod" as the variable $v and put it in:

man $v >~/Manuals/man_$v.txt

and then it will do this:

man chmod >~/Manuals/man_chmod.txt

Just a thought.
In case you're wondering I'm still new enough to Linux that I'm collecting Man Pages to read at leasure. :)

No, alias only expand the left hand side to the right. If you want to use arguments use a function.

BTW if you just want man to dump output to the terminal then just do

#man use the default pager in the environment variable $PAGER, the default is 'less'
#to not use it, do
PAGER="" man chmod

A simple redirection can save the output.

Thanks for the reply.

OK, that answers that question.
Now to find out what a "function" is.
I have NO programming skills and have just started creating aliases because of this thread.
I'm so green behind the ears that Mother Nature is jealous of me.

BTW if you just want man to dump output to the terminal then just do

I think you misunderstood me, if I'm reading this right.
I know I can "man foo" and read everything in the terminal, I want to create a text file of man pages I look at.

What do you mean by:

dump output to the terminal

#man use the default pager in the environment variable $PAGER, the default is 'less'
#to not use it, do
PAGER="" man chmod

A simple redirection can save the output.

Wouldn't:

man chmod >man_chmod.txt
be simpler for my purposes?

I know I can "man foo" and read everything in the terminal

Man let you read the manual through a 'pager' program so that you can go back and forth and search for pattern etc. It does a number of things under the surface to format the page, e.g. wraping the text for different terminal size. Then it 'pipe' the output to the pager program. Usually this is the program called 'less'.

Under the surface, it does sth similar to

cat somefile | less # pipe the content to through 'less', vs.
cat somefile # dump the content to the file to terminal

Just to illustrate what I was trying to say, try this and see the difference when changing MANWIDTH

PAGER="" MANWIDTH=100 man chmod

This gets into the topic of environment variable in shell scripting, which I won't try to explain. Many excellent tutorials exist.

This is a pretty crazy one. I wouldn't recommend using it on a local machine because it will be very annoying every time you open a terminal. But it's really cool for a machine that you never log in to locally, but over SSH.
It's based on the default .bashrc of Ubuntu but with some modifications.

The hard coded Distro name should not be hard coded
The Previous login host is actually displayed as the current host you're logging in from
Displaying amount of RAM in MB instead of KB

This is really cool for remote logins. :)

It's not very clean, but the comments should be enough.
Interesting features:
-Special PS1 only for Konsole terminal putting directory name in the tabs. Otherwise I get errors when using it in other terminals.
-Play sound everytime you run a command (commented out, there's also a thread about it somewhere)
-Command numbering

# ~/.bashrc: executed by bash(1) for non-login shells.
# see /usr/share/doc/bash/examples/startup-files (in the package bash-doc)
# for examples

# If not running interactively, don't do anything
[ -z "$PS1" ] && return

# don't put duplicate lines in the history. See bash(1) for more options
export HISTCONTROL=ignoredups

# check the window size after each command and, if necessary,
# update the values of LINES and COLUMNS.
shopt -s checkwinsize

# make less more friendly for non-text input files, see lesspipe(1)

Hi FuturePilot,

Thanks, that was fun. :)

There's a few little glitches I've been trying to work out.

The hard coded Distro name should not be hard coded

echo -ne "$LightBlue Distro: $LightGreen `lsb_release -sd`";

Should do what you want.

The Previous login host is actually displayed as the current host you're logging in from

Have a look at with $SSH_CONNECTION

You could probably have a play with sed and grep it from /etc/hosts.

Displaying amount of RAM in MB instead of KB

and checking the info.sh script from http://ubuntukids.org/blog/?page_id=25

let memtotal=`grep "MemTotal" /proc/meminfo|cut -c 12-22|indent -i0`/1024
echo "Memory Total: $memtotal mb"
let memfree=`grep "MemFree" /proc/meminfo|cut -c 12-22|indent -i0`/1024
let memcache=`grep "Cached" /proc/meminfo|cut -c 12-22|indent -i0`
let memcache=$memcache/1024
let memfreetotal=$memfree+$memcache
echo "Memory Free: $memfreetotal mb"

will give you MB. You will need to get the indent program thats in the repos to use it as is.

For brevity's sake I'm only including stuff I haven't seen in the last 8 pages.

alias tf='tail -f'
I follow a lot of log files and this one just makes sense.

alias sudo='A=`alias` sudo '
Runs alias before running sudo, somehow preserving all your alias bindings in the sudo command. So if I did sudo tf /var/log/file, it would still work even though root doesn't have my alias file.

alias su='su -m'
Preserves my env variables when I switch user. Useful because it includes my prompt, which flashes red when I'm root. Sometimes I don't want it so I fall back to /bin/su to ignore the alias.

function lw() {
if [ $# -gt 0 ] ; then
for bin in $@ ; do ls -lh `which $bin` ; done
else
echo "lw (ls which) requires more than 0 arguments"
fi
}
Lastwhich (lw) is new for me and I'm not sure if I'll keep it. I use it for finding the path of a symlink. For instance, lets say I don't know which version of java I'm using and several are installed. I usually type "which java" and that tells me it's coming from /etc/alternatives/java. That's not useful so I type "ls -lh `which java`" (the command in the backticks executes first, so I am effectively doing ls -lh /etc/alternatives/java in fewer keypresses). Since I can't alias a variable into a backtick, this one had to be a function. I figured I might as well let it do several files at once, hence the for loop, though I'm not sure I'll actually use that feature. I still feel dirty putting this in my .alias file.

I know this isn't for .bashrc, but fans of screen will appreciate this:
caption always "%{= ..}%-w%{= BW}%n %t%{-}%+w %-= @%H - %D %d %M - %c"

It puts a line at the bottom of your screen session. That line includes the names and numbers of open windows, so it looks like tabs. Now I don't need a fancy terminal window as long as screen is installed. For added fun, it includes the host and date too.

--

I put all these rc files (plus some other fun stuff like my authorized_keys) in a CVS repository. Whenever I change my .bashrc I can push the change into CVS and then check it out at any machine I might visit later. Given that I have several dozen accounts this is a huge time saver.

Here is my bashrc:

...
myip=`lynx -dump -hiddenlinks=ignore -nolist http://checkip.dyndns.org:8245/ | sed '/^$/d; s/^[ ]*//g; s/[ ]*$//g' `
...

Just a suggestion:

lynx -dump -hiddenlinks=ignore -nolist http://checkip.dyndns.org:8245/ | grep "Current IP Address" | cut -d":" -f2 | cut -d" " -f2
It's easier to understand. :)

Can you explain me what exactly

sed '/^$/d; s/^[ ]*//g; s/[ ]*$//g'
does? I mean, how does it work? Because I cannot understand it.

Just a suggestion:

lynx -dump -hiddenlinks=ignore -nolist http://checkip.dyndns.org:8245/ | grep "Current IP Address" | cut -d":" -f2 | cut -d" " -f2
It's easier to understand. :)

Can you explain me what exactly

sed '/^$/d; s/^[ ]*//g; s/[ ]*$//g'
does? I mean, how does it work? Because I cannot understand it.

It does 3 things:
1) /^$/d ->remove empty lines (search for pattern "^$" and delete corresponding lines)
2) s/^[ ]*//g ->remove spaces at the beginning of lines (substitute matches for "^[ ]*" with "" globally)
3) s/[ ]*$//g ->remove spaces at the end of lines (substitute matches for "[ ]*$" with "" globally)

regular expression basics:
^:beginning of line
$:end of line
*:repeated any number of times ([ ]*=any number of spaces)

For more details:
http://www.grymoire.com/Unix/Sed.html
http://www.regular-expressions.info/

And I have a question too:
What IP address does that site/command give?
It's obviously not my local IP address (from ifconfig).
Is it my modem/router's IP address?

P.S: Thanks for the cut command and the dotfiles.org site. :)

Thanks for giving the detailed explanation. Saves me the time and effort to write it all down myself :)

That first link you gave for sed (http://www.grymoire.com/Unix/Sed.html) is the very best guide for sed I've found; up until I read that a short while ago sed didn't make much sense to me.

I'm not sure what IP address it gives. I haven't used that alias in a long time and no longer have lynx installed. I also did not write the alias myself but found it somewhere online; it initially looked neat, but I found I had no use for it. I haven't bothered to delete it from my bashrc though. (I carry a few other aliases that I haven't used in a while around).

I suppose the router IP address would make sense, though.

myip=`lynx -dump -hiddenlinks=ignore -nolist http://checkip.dyndns.org:8245/ | sed '/^$/d; s/^[ ]*//g; s/[ ]*$//g' `
echo "${myip}"

i dropped lynx in favor of w3m (a really great pager/browser) a long time ago. the lines above can be changed to just

myip=`w3m -dump http://checkip.dyndns.org:8245/`
echo "${myip}"

this is only useful if your ip address is changing frequently (some providers assign a new ip every time you reconnect to their service).

I have my PS1 set like this:

PS1='\n\D{%Y-%m-%d_%H:%M:%S_%a}, \!\n${debian_chroot:+($debian_chroot)}\u@\H:\ncd \"\w/\"\n'

Thinking it would help, being able to cd by copying and pasting, or using middle click, to this output to change the directory, but in directory ~/, etc it outputs
cd "~/"
pasted(or middle click) + Enter key gives
bash: cd: ~/: No such file or directory

How can I get cd "~/" etc... working or get it to display the full path without the "~/"?

p.s. it looks like this:

2008-08-02_16:38:38_Sat, 505
bryan@bryan-laptop:
cd "~/"

with the time going from largest value to smallest value followed by day of week, comma space, then followed by history number and a new line, then my user info, colon, and a new line, then cd and the path of the directory, and another newline.

This is also good for copying and pasting date/time for sorting purposes.

Other variations on this
(these might seam weird, and you might end up trying to backspace where nothing will happen!):

PS1='\n\D{%Y-%m-%d_%H:%M:%S_%a}, \!\n${debian_chroot:+($debian_chroot)}\u@\H:\n\w/\n'
PS1='\n\D{%Y-%m-%d_%H:%M:%S_%a}, \!\n${debian_chroot:+($debian_chroot)}\u@\H:\n\w/'
Now with color:
PS1='\n\[\033[01;33m\]\D{%Y-%m-%d_%H:%M:%S_%a}, \!\n${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\H:\n\[\033[01;34m\]\w\[\033[01;37m\]/'
#found Color info here: http://ubuntuforums.org/showthread.php?t=674446

Note: this add an extra '/' which works fine for all directories except for the '/' directory.

when I want to edit my conky stuff I created an alias in my bashrc:

conk for conky + e for edit

conke
actually does this:

alias conke='(gedit ~/.startconky ~/Conky/conkymain ~/Conky/conkyforecast ~/Conky/conkyemail ~/Conky/fortune ~/Conky/scripts/SP_Forecast.py ~/Conky/scripts/EN_Forecast.py ~/Conky/scripts/mail/conkyEmail.py ~/Conky/scripts/myweather.template ~/Conky/scripts/argentina.template ~/Conky/scripts/otherweather.template &)'

It's a shellscript that's run every time you open a terminal, so it can do much more powerful things than just "make a command". ;)

-You can change your command prompt.
-You can set environment variables.
-You can display some info as a welcome message.
-You can create specific prompts depending on the terminal used.
-You can make terminal tabs/title bars display your current directory.
-You can add sounds for every command you enter. (my favorite, altough not practical for general use. :roll: )

The biggest problem with zsh is finding a decent .zshrc :

http://zsh.dotsrc.org/Contrib/startup/std/zshrc

use google to find others :)

then read through them to understand what you are doing and make a few adjustments ....

http://friedcpu.wordpress.com/2007/07/24/zsh-the-last-shell-youll-ever-need/

This is what a good .zshrc can do for you (although there are better, if you look close you will see that is zsh on cygwin in Windows):

anyone know how to make an alias for the "mount iso" procedure? I just want to input "miso data.iso" and ta-dah iso file is mounted to my ~/nomada dir

while aliases can't take variables, functions sure can. since i liked the idea, and it seemed to be good exercise for a beginner like me, here it is:

miso()#mount iso file
{
_mountpoint=/home/weirdo/iso
if [ -z $1 ]; then
echo -e "usage:\tmiso file.iso\n\tmiso -u"
elif [ $1 = "-u" ]; then
sudo umount $_mountpoint && echo "$_mountpoint unmounted."
elif [ -r $1 ] && [ ! -z `echo $1 | grep -i .iso$` ]; then
if [ `ls $_mountpoint | wc -w` -ne 0 ]; then
echo "error: $_mountpoint is not empty."
else
sudo mount -o loop $1 $_mountpoint && echo "'$1' mounted to $_mountpoint."
fi
else
echo "error: '$1' is not a readable iso file."
fi
}

shell functions can be specified right inside the ~/.bashrc file. there are a few really useful ones in this thread :)

interesting :D
does that alias also unmounts the iso? thanks!

The function (not an alias) posted by kaiju above does this, yes (using -u switch).

echo "error: $_mountpoint is not empty."
else
sudo mount -o loop $1 $_mountpoint && echo "'$1' mounted to $_mountpoint."
fi
else
echo "error: '$1' is not a readable iso file."
fi
}

I tried this with a filename that has spaces (miso "My File Name with spaces and with or without Path in quotes.iso") and get
bash: [: too many arguments
bash: [: too many arguments
bash: [: too many arguments
error: 'My File Name with spaces and with or without Path in quotes.iso' is not a readable iso file.

It did work with my File that didn't have any spaces in it's name and path, rather or not I used quotes.

p.s. I changed "/home/weirdo/iso" to "/Drives/Mounted_iso/Default"

Is there a way to make your bash prompt and any text that you type after it a different color? When using bash, I'll often get a lot of text back and it's hard to find where it starts (at the last prompt). It would be useful to color the prompts.

Yes. It involves sending a terminal control sequence using "\[" as part of your PS1 prompt variable. The actual sequence that has to be sent varies depending upon the actual terminal that is being used (console/xterm/gnome-terminal/etc), but I think most use the same escape sequences for setting the colors. Search google for "color bash prompt" and you will find several guides on how to do it.

did that, still getting the last error

error: 'My File Name with spaces and with or without Path in quotes.iso' is not a readable iso file.

double quotes (",") worked for names without spaces, but single quotes (',') didn't even work for that.

miso()#mount iso file
{
_mountpoint="/Drives/Mounted_iso/Default"
if [ -z "$1" ]; then
echo -e "usage:\tmiso file.iso\n\tmiso -u"
elif [ "$1" = "-u" ]; then
sudo umount $_mountpoint && echo "$_mountpoint unmounted."
elif [ -r "$1" ] && [ ! -z `echo "$1" | grep -i .iso$` ]; then
if [ `ls $_mountpoint | wc -w` -ne 0 ]; then
echo "error: $_mountpoint is not empty."
else
sudo mount -o loop "$1" $_mountpoint && echo "'$1' mounted to $_mountpoint."
fi
else
echo "error: '$1' is not a readable iso file."
fi
}Seems like it's this line that causes the error:

elif [ -r "$1" ] && [ ! -z `echo "$1" | grep -i .iso$` ]; then

In order to make the shell treat spaces as non-separating characters, you can set the internal field separator to newline, just make sure you reset it to the original value before the process exits (very important if used in a bash function).

# save the original IFS
_ifs=$IFS
# change the value to newline
IFS='
'
### rest
### of
### the
### script
# reset IFS to the original value
IFS=$_ifs

Note: To unset the variables that were used in a shell function, you can use unset -v VARIABLE (without the leading '$'), so that the variables don't clutter up the environment and are recreated every time the function is run, just as if it were a normal script.

I tried that an it didn't work. However, I did try getting rid of the line(s) that I thought were causing the problem and it worked. What did that line do? Was it just a check to see if the file ended in .iso, or did it do anything else? Anybody know if this will this cause any problems?

Seams to work for me. Anybody see any problems, or better ways to do this?

[...] What did that line do? Was it just a check to see if the file ended in .iso, or did it do anything else?

short answer: it should check whether '$1' is a readable with its file name ending in '.iso' (or .ISO, .Iso, etc.)

elif [ -r "$1" ] && [ ! -z `echo "$1" | grep -i .iso$` ]; then

"elif" and "; then": part of the if-then-else logic
"[ -r $1 ]": true if '$1' is a readable file; just to avoid passing mistyped words
"`echo "$1" | grep -i .iso$`": true if the file name has '.iso' at the end ($), case-insensitively (grep -i); to avoid passing anything but iso files
"[ ! -z `TEST` ]": true if the string returned by `TEST` is non-zero (that will mean that grep found the file name to be ending with '.iso')

i suspect the problem to have been caused by the latter part - with the string returned by grep, '[ ! -z File Name With Spaces.iso ]' will error out
this can probably be circumvented by enclosing the `TEST` part within double quotes

then again, this whole part might not be necessary at all, i just like doing tests to make sure my scripts return somewhat informative error messages

$SSH_CONNECTION will only be set if bash is running in an ssh client, so its value can be used to detect an ssh session
the root part will only work if we're using the root account with sudo (e.g. 'sudo -s' or 'sudo bash'); using su will lead to /root/.bashrc being sourced instead of the current ~/.bashrc

i didn't yet figure out how to test for the case when i'm both logged in through ssh and using the root account, so that i can have a red \u@\h:\W for the prompt, instead of the plain \u:\W
any ideas anyone?

Thanks kaiju
That fixed it!
and now I also modified the code to accept a mountpoint that has spaces in them.

miso() # mount iso file
{
_mountpoint="/Drives/Mounted_iso/Default"
if [ -z "$1" ]; then
echo "usage:"
echo " miso file.iso to mount FILE.iso at '$_mountpoint'"
echo " miso -u to unmount FILE.iso from '$_mountpoint'"
echo " Where FILE.iso is the name, or path and name, of the iso file to mount"
elif [ "$1" = "-u" ]; then
sudo umount "$_mountpoint"
echo "'$_mountpoint' unmounted."
# if you don't want to verify if the file name ends in a .iso
# (case insensitive, -i) remove
# && [ ! -z "`echo "$1" | grep -i .iso$`" ]
elif [ -r "$1" ] && [ ! -z "`echo "$1" | grep -i .iso$`" ]; then
if [ `ls "$_mountpoint" | wc -w` -ne 0 ]; then
echo -e "error: '$_mountpoint' is not empty, \ntry miso -u to unmount it"
else
sudo mount -o loop "$1" "$_mountpoint"
echo -e "'$1'\n is mounted at\n'$_mountpoint'"
fi
else
echo "error: '$1' is not a readable *.iso file."
fi
}

a way to quickly list, view, edit and source a ~/.bash_functions file
of course it will only work with an editor that will take +N FILENAME to mean that we want to open FILENAME at line N (nano and vim work fine)

func(){ #view and edit ~/.bash_functions
if [ "$1" = "ed" ]; then
_LINEN=`grep -n ^${2}.*\{\ \# ~/.bash_functions | head -n 1 | sed 's/:.*//'`
$EDITOR +${_LINEN} ~/.bash_functions
source ~/.bash_functions && echo "info: ~/.bash_functions sourced"
elif [ "$1" = "ls" ]; then
less ~/.bash_functions
else
grep \{\ \# ~/.bash_functions | sed -e 's/(){//' -e 's/ #/ - /' | sort
fi
unset -v _LINEN
}

as you can see from the grep line, the pattern searching part is tuned to the format of the first line - that line is used to find out where a given function starts (for jumping to the first function that matches $2 when editing) and also to provide a quick description (for when we're just listing the functions contained in the file)

Hi all,

I've just been modifying my default out-of-the-box .bashrc with some of the suggestions above and seem to have messed something up so that when I type a command of a certain length, instead of looping onto a new line it overtypes what I've just written... It only does this once, if I keep on typing then (what should be the 3rd line) loops onto line 2.

Any ideas what I've done? See my .bashrc below:

I had the same problem once.
It's because you didn't use the '\[' and '\]' to indicate beginning and end of a sequence of non-printing characters.

Here's a fixed version of your .bashrc:

I had to add other color commands for the echo command because otherwise it displays '\[\]' for each color command.
There may be a better way to do this like using several echo commands, but this works. :)

After a long time of intending to sit down and create a nice bashrc for myself I finally sat down today and went through this thread to do it. It's still a work in progress so I'm still not quite posting the full thing, however, I really liked the netinfo function in urukrama's 1st post but wanted to make it more readable so I'm posting that. I hadn't worked much with awk so I used this as a nice little primer and also tried to brush up on my bash scripting. Here it is:

netinfo()
{
n=1 # Placeholder

# Grab ethernet interface
for x in $(ifconfig | awk '/eth/ {print $1}')
do
eth[n]=$x
let "n += 1"
done

# Grab HW address
let "n = 1"
for x in $(ifconfig | awk '/eth/ {print $5}')
do
hwAddr[n]=$x
let "n += 1"
done

# Grab IP address
let "n = 1"
for x in $(ifconfig | awk '/inet addr/ {print $2}')
do
y=$(echo $x | awk -F : '{print $2}')
ipAddr[n]=$y
let "n += 1"
done

# Grab broadcast address
let "n = 1"
for x in $(ifconfig | awk '/Bcast/ {print $3}')
do
y=$(echo $x | awk -F : '{print $2}')
bAddr[n]=$y
let "n += 1"
done

# Grab mask
let "n = 1"
for x in $(ifconfig | awk '/Mask/ {print $4}')
do
y=$(echo $x | awk -F : '{print $2}')
mask[n]=$y
let "n += 1"
done

echo "----------- Network Information ---------"
let "n = 1"
echo
for x in ${eth[@]}
do
echo "Ethernet Interface: ${eth[n]}"
echo "HW Addr: ${hwAddr[n]}"
echo "IP Address: ${ipAddr[n]}"
echo "Broadcast Address: ${bAddr[n]}"
echo "Mask: ${mask[n]}"
echo
let "n += 1"
done
echo "-----------------------------------------"
}

Can you tell I do a lot of C? Haha

Anyways, I turned a less than 10-liner into around 60 lines and the looping in it is sloppy :-?. But I'm tired so hopefully by posting it somebody else can improve more on it :lol:

Hi!

I manually searched each page of this topic for 'cd' but it seems that few people thought that you could take the 'back' (as an alias of 'cd $OLDPWD') process one step further.

This is my first solution:

HISTORY=-1
export HISTORY

HISTORYARRAY[0]=$PWD
export HISTORYARRAY

# aliases
alias cd='HISTORY=$(($HISTORY+1)); HISTORYARRAY[$HISTORY]="$PWD" ;cd'

alias back='if [ $HISTORY -lt 0 ];then echo "cannot go back before initial position";else builtin cd ${HISTORYARRAY[$HISTORY]}; HISTORY=$(($HISTORY-1)); fi'

but this solution didn't support spaces in paths. Reading things through the web gave me this more pleasant solution:

alias cd='pushd'
alias back='popd'

It would be more user-transparent if names of directories wouldn't appear when changin' directory. This would be resolved by converting it into a function with output redirection, but I prefer remembering that I'm using pushd.

Someone recently suggested me an 'next' but I don't fell like trying to do it now.

This may be a dumb question, but I'm just starting to learn how to customize using bashrc.

I've managed to modify my prompt using colors, etc., but how do I change the colors of the output of some commands to match my prompt? e.g. ls

EDIT: Aah, are they defined in $HOME/.dir_colors?

I've been having a strange behaviour of the cd command for quite some while now and finally found the cause: My .bashrc (which I copied from someone else) contained the following line:

export CDPATH=.:$HOME

This lead to cd searching through the home directory as well as the current directory when pressing tab multiple times.

In case someone would like such a behaviour, here's more info:

I cleaned up my bash files a little bit.
Setting the PATH=something:$PATH in ~/.bashrc is not a good idea, since PATH will keep getting bigger if you launch a new bash from within bash.

So I put all export PATH/LD_LIBRARY_PATH, etc (i.e. all the environment setup) + all private info in ~/.bash_profile. This should also make it easier to use them on other machines: Nothing to change except the contents of ~/.bash_profile (hopefully).

I also split my .bashrc into smaller files for more modularity.

i use this all the time. super quick, super easy.

must install 'lynx' first -- very small CLI web browser.

echo ${WEATHERARRAY[@]}
}

i can't remember if 'curl' is installed by default.

zsh ftw :)

The biggest problem with zsh is finding a decent .zshrc :

I just made my zsh into the best thing ever :)

Here's how to make zsh set an xterm title with the currently running command. For people who like to use the less command and operate lots of xterms at once, I'm sure you'll find a million uses for this!

In zsh, just add the following somewhere:

case $TERM in
xterm*)
preexec () {
print -Pn "\e]0;`basename $PWD`: $2\a"
}
;;
esac
`basename $PWD` means that the title displays the name of the current directory and none of the trailing directories. Just a bit of context for the important part, which comes from $2, which is provided courtesy of zsh's preexec function. (There are 3 arguments. $1 is what the user typed, $2 and $3 are that formatted in different ways).

Unfortunately it's a bit trickier to accomplish in Bash, but here you go:
http://www.davidpashley.com/articles/xterm-titles-with-bash.html

The rest of my .zshrc is pretty boring.

bash prompt / PS1 string styling line wrapping troubleshooting:

1) Box drawing characters screwing up line wrapping
I had some problems with my new bash prompt using box drawing characters (http://en.wikipedia.org/wiki/Box-drawing_characters) (─,┌,┐,└).

I finally managed to solve it. All you have to do is put "\[" and "\]" around those characters. :)

Here's my new PS1 string:

export black="\[\033[0;38;5;0m\]"
export red="\[\033[0;38;5;1m\]"
export orange="\[\033[0;38;5;130m\]"
export green="\[\033[0;38;5;2m\]"
export yellow="\[\033[0;38;5;3m\]"
export blue="\[\033[0;38;5;4m\]"
export bblue="\[\033[0;38;5;12m\]"
export magenta="\[\033[0;38;5;55m\]"
export cyan="\[\033[0;38;5;6m\]"
export white="\[\033[0;38;5;7m\]"
export coldblue="\[\033[0;38;5;33m\]"
export smoothblue="\[\033[0;38;5;111m\]"
export iceblue="\[\033[0;38;5;45m\]"
export turqoise="\[\033[0;38;5;50m\]"
export smoothgreen="\[\033[0;38;5;42m\]"
export defaultcolor="\[\e[m\]"
PS1="$bblue\[┌─\]($orange\$newPWD$bblue)\[─\${fill}─\]($orange\u@\h \$(date \"+%a, %d %b %y\")$bblue)\[─┐\]\n$bblue\[└─\](\$newRET)(\#)($orange\$(date \"+%H:%M\")$bblue)->$defaultcolor "

cf my previous post for the full .bashrc. I don't have a clean one I can post here right now.

2) Unicode/Box drawing characters not displaying correctly in Konsole/Yakuake/etc:

Settings->Encoding->Unicode (utf8)
Settings->Save as default

3)Colors & co screwing up line wrapping:
Surround the color statements (those beginning with "\e", "\033")(more generally: all "non-printing" characters) with "\[" and "\]".
Also, make sure you end the PS1 string with "\[\e[m\]" if you want to get back to default colors for input.

Just for reference, from man bash:

\[ begin a sequence of non-printing characters, which could
be used to embed a terminal control sequence into the
prompt
\] end a sequence of non-printing characters

Note: This should probably be added to some big bash prompt styling guide. :)

I may get **** for reviving an old thread, but here's mine.

http://omploader.org/vNHB0dg

.bashrc and .tmux.conf are attached.
You'll want to save them directly (Opening the bashrc in your browser won't display symbols correctly).

Also, you'll have to rename them to remove the .txt from the ends.

Edit: Fixed a bug and added the root .bashrc as well (red instead of blue)

Thanks everyone for sharing, I've learnt a lot from this thread.
Here's mine, it's a cleaner version of this one: http://ayozone.org/2008/02/25/bash-fancy-prompt-and-improvments/ (my thanks to the author)

It also shows git branches and a smiley that changes if the previous command errored. Colours are meant to match the 10.04 scheme.

Here is mine. It's mainly a collection of commands from this tread. The only new part is the duf function:

# show the 10 largest files sorted and in human readable format
function duf {
du -sk "$@" | sort -n | while read size fname;
do for unit in k M G T P E Z Y;
do if [ $size -lt 1024 ];
then echo -e "${size}${unit}\t${fname}";
break; fi; size=$((size/1024));
done;
done | tail -n 10 | tac
}

I'll play along.

First for the pretty:

Now to the code:

How do you get the terminal to display your name as [name] instead of name@computername? I tried to find that part in your script but can't see it.

in bash the prompt is "PS1"

from the bashrc posted the line, at the bottom, is

PS1="\[[31m\][\[[32m\]\u\[[31m\]]\[[32m\]\w > \[[39m\]"

These have all been like insanely helpful, but I'm really confused on how do you do color etc.? Thanks!!

Read up on how to change the colors in your terminal online. It's really not that hard, especially since most browsers have a convenient search bar built-in.

Anyway, anyone look at the ulitmate .bashrc (http://ubuntuforums.org/showthread.php?t=1693307) I linked to earlier? Believe me, it's useful as hell.

EDIT: Here's my .bashrc as it currently stands:

Hi,

As you might know, you can make your own "commands" in the terminal by adding aliases in a file called .bash_aliases in your home directory.

You can add more or less useful stuff as bash aliases, and I want to know which ones you have made that makes your life easier?

Here are mine:

alias f='more ~/.bash_history | grep '

This one makes it damn easy to find previous commands, just type: f whatever, and all commands that contains 'whatever' comes up. I think this works better than CTRL+R and so on.

alias suno='sudo nano'

Nano as root = suno :)

alias upgrade='sudo apt-get update && sudo apt-get upgrade'

Typing upgrade refreshes the repositories and suggests updates to install.

alias ll='ls -lh'
alias la='ls -A'
alias l='ls -CF'

These are not mine, but very handy - shortens the use of ls variations.

Keep'em coming!

alias 'cd..'='cd ..'

alias back='cd - > /dev/null'
alias home='cd ~'

alias back='cd - > /dev/null'
alias home='cd ~'

You do understand the cd , without any arguments, goes to home ?
home is also abbreviated with a tide ~

so

cd

is much shorter then typing 'home'

also there is already a .bashrc thread, which I will merge this into ...
