Share your commandline cheat sheets

[billgoldberg]

Ok, I have been needing to do this for a long time.

I need a cheat sheet of commands.

I know there are some on the web, but they are mostly basic lists.

Do you have a list with useful commands?

Share them.

(I'll be happy to rip them)

ps: I have a basic one here:

http://linuxowns.wordpress.com/2008/04/23/hardy-cheat-sheet/

[dbbolton]

It seems kind of redundant to open a root shell with sudo. I guess it's because Ubuntu doesn't set a root password by default.

Here are some handy basic commands to know:

cat - print contents of a file
cd - change directories
chmod - change file permissions
cp - copy a file
grep - searches for a given string
ln - link files
ls - list the files in the current directory
mkdir - make directory
more - helps page through output ( cat file.txt | more)
mv - move a file
rm - delete files and directories
top - shows resource usage

Helpful symbols:
| - pipe the output of one command into the next
& - detach process from shell (run in background)
&& - chain two or more commands together (if the first is successful)

[hansdown]

Fosswire has a couple good printable sheets.

And don't forget the >
useful when doing top > top.txt or lspci > log.txt

[crimesaucer]

These 4 commands are useful:




-- CHANGE folder of .svg's to .png's and resize all the images:


for i in *.svg; do inkscape -f "$i" -e "$i.png" -w24 -h24; done




-- CHANGE one .svg to a .png and resize the image:


inkscape *.svg --export-png=*.png -w24 -h24



-- check hard drive temp:



hddtemp /dev/sda


-- GDM screenshot:

One I use a lot is:

ls -ltr
ls -a -ltr

Aliases are quite handy, especially ones for apt and tar, as the most command things I do are rather verbose.

[urukrama]

Interesting.

[caljohnsmith]

Only if you have a wireless card would you be interested in this one...

watch 'sudo iwlist wlan0 scan | grep -A 10 -B 1 "My Home WLAN"'
The command will update every two seconds (at least it tries to, but the iwlist scan is slower sometimes), so you can see how the signal strength of "My Home WLAN" changes as you move your computer or antenna around to tweak for the best signal.

[MaxIBoy]

Actually, that's exactly what I needed on my laptop. Now if only I knew the command to join a wireless network, I would be able to spend whole days in textmode, which would be very cool.

Do you mean like "ifconfig wlan0 essid *"?

[unutbu]

isconnected.py:

#!/usr/bin/env python
import os
print True if os.system('dig +time=1 +retry=0 192.168.1.1 2>/dev/null 1>&2')==0 else False
This checks if my network connection is running.
If the connection is down, it reports "False" after a short timeout. I haven't found a way to make ping's timeout (ping -w1) work similarly.

Oh! I was muddling around with iwconfig.

I know this is a basic list of commands but the examples were excellent for me to get the hang of the command line. I learn by doing. And trying out these were a nice opportunity to learn the basics but in a better way than any of the other basic manuals which all seem to say exactly the same thing by doing. And trying out these were a nice opportunity to..oops! now I'm doing it.

[caljohnsmith]

EDIT: Actually, I just realized that the following does not really fit in with the original thread subject (sorry about that), but I'll leave it in case someone might find it useful anyway.

When you run a command from a launcher as "run in terminal", it closes the terminal as soon as the command completes, which can be really annoying if you want to see the output of the command. So instead of using the "run in terminal" option, just run the command or bash script with:

gnome-terminal -x bash -c "<commands or bash script>;read -n1"
The "read -n1" makes it so the terminal won't close until you press some key. For instance, to see who you are logged in as, your kernel version, and your free RAM and swap space (just a random cheesy example):

gnome-terminal -x bash -c "whoami;echo;uname -r;echo;free;read -n1"
The "echo" commands are just to create a new line between the other commands to make it look at little bit nicer.

Another really good option for running commands/bash scripts in a window is zenity:

{ whoami;echo;uname -r;echo;free; } | zenity --text-info --width=600 --height=500 --title="Cheesy Command Example"
And of course there are a lot of great possibilities with Zenity in bash scripts, but I assume that this thread is for commands that can be directly run at the command line. :)

Here's a complete overload of commands related to package management :shock::

To search which installed package a file/program comes in:

dpkg -S <file/program>
(Note that the search term will be treated as a substring, no need to use any asterisks *). Also similar is:

dpkg-query --search <file/program>
To search which installed or uninstalled package a file/program comes in:

sudo apt-file -v update [if haven't done it recently]
apt-file search <file/program>
(Again no need for *, the search term will be treated as a substring). To search the installed/uninstalled package names/descriptions for a key word:

apt-cache search <key word>
To search for available versions of a package, or to show the version all ready installed, and to show which repository it is available in:

apt-cache policy <package>
To try installing a different version:

sudo apt-get install <package>=version
To add a CD-ROM as a repository (like the Ubuntu Live CD):

sudo apt-cdrom add
Get a list of all installed packages:

dpkg --get-selections
Format and output that list into a file:

dpkg --get-selections | grep '[[:space:]]install$'| awk '{print $1}' > installed_packages.txt
To search through all installed packages for a substring in the package name, e.g. to find nautilus related packages:

dpkg --get-selections *nautilus*
Similar is:

dpkg -l *nautilus*
To use dpkg to install a bunch of .deb files in a directory:

sudo dpkg -i /directory/*.deb
Reconfigure an all ready installed package:

sudo dpkg-reconfigure <package>
To clean out packages in /var/cache/apt/archives:

sudo apt-get clean
To list the dependencies of a package:

apt-cache depends <package name>
(Note the file that keeps track of installed packages is /var/lib/dpkg/status). To find dependencies of packages:

sudo debfoster

[rakris]

Yes I did just that in post #43. click the link and try the examples out, they're all good and unique

Wow. That was very helpful..Thanks...

[ukripper]

Some commands from my personal commands-list:

Useful Commands



find / -user "alex" -exec cp {} /groups/sales \;


The command find / -user "alex" will find all files created by user alex. The fun thing about find is

that you can execute a command on the result of the find command by using the -exec

option. For example, if you want to copy all files of user alex to the directory /groups/sales,

use find / -user "alex" -exec cp {} /groups/sales \;. In such a command, you should

pay attention to two specific elements. First is the {} construction, which is used to refer to the

result of the find command that you’ve started with. Next is the \; element, which is used to

tell find that this is the end of the part that began with -exec.




find / -user susan –exec grep root {} \;


To illustrate how this rather complex construction works, let’s have a look at another

example. In this example you want to search all files owned by user susan to check if the word

“root” occurs in it. So the first thing you’d need to do is find all files that are owned by user

susan, and you’d do this by typing find / -user "susan". Next, you need to search these files

to see if they contain the word “root”. To do this, you’d need a construction like grep root *.

However, that construction is not the right way of doing it, because the grep command would

search all files in the current directory. Therefore, you first need to combine the two commands

using -exec. Next, you need to replace the * from the grep root * example by {}, which

refers to the result of the find command. So the final construction would be find / -user susan –exec grep root {} \;


To find drivers being used for network:

lshw -C network

To change the permissions back to original owner:


sudo chmod -R 600 /home/john && sudo chown -R john /home/john



VBOX
Code:


sudo aptitude install virtualbox-ose virtualbox-ose-source

From reading other docs, it turns out that sometimes the kernel modules break when the kernel image upgrades. One of the bug comments had instructions for building the modules:

Code:


sudo aptitude install build-essential module-assistant
sudo m-a update
sudo m-a prepare
sudo m-a a-i virtualbox-ose
sudo /etc/init.d/vboxdrv restart



HDD TOOLS

Here are some useful commands for troubleshooting:

To search all logs for keywords:

Code:


sudo egrep -i 'keyword1|keyword2|keyword3' /var/log/* > ~/errors

Note I am directing the output of the egrep search to a file in the home directory named "errors". It's easier to look and search through the file instead of scrolling though the terminal.

To get info on your partitions:

Code:


sudo hdparm -I /dev/sda > ~/sda_info

Again the output is directed to a file for easier viewing.

To run SMART tests on your hard drive, first install smartmontools, then:

Code:


sudo smartctl -t long /dev/sda

Then a few hours later run the following to see the final results:

Code:


sudo smartctl -l selftest /dev/sda

You can also look at the history of SMART errors being logged by the drive:

Code:


sudo smartctl -a /dev/sda

To check a drive for badblocks, boot with the live CD, don't mount the drive, find out which partition you want to scan using "sudo fdisk -l", then:

Code:


sudo badblocks -nvs /dev/sda

You can also do this, check the man page for more options:

Code:


sudo e2fsck -cfp /dev/sda1

The following will tell you if there are any blocks marked as bad on your partition:

Code:


sudo dumpe2fs -b /dev/sda1

This command lists all the IRQs and the devices assigned to them:

Code:


cat /proc/interrupts

BACKUP
How to backup/sync using rsync over SSH

In Terminal use following to check SSH is working:

$ ssh username@ip-address-remote-machine
create rsync script:

#! bin/bash

echo this script will backup to remote server
echo backup starting.......

rsync -e "ssh" -avz --progress --exclude=directory/ ~/ebooks/ username@ip-address-remote:/media/hdd/LINUX-BACKUP/server-backup
/VOSTRO/ebooks/

echo start Music sync.....

rsync -e "ssh" -avz --progress ~/Music/ username@ip-address-remote:/media/hdd/Multimedia/Music/

#rsync -e "ssh" -avz --progress ~/movies/ username@ip-address-remote:/media/hdd/Multimedia/movies/

rsync -e "ssh" -avz --progress ~/.evolution/ username@ip-address-remote:/media/hdd/LINUX-BACKUP/server-backup/VOSTRO
/.evolution/

rsync -e "ssh" -avz --progress ~/scripts/ username@ip-address-remote:/media/hdd/LINUX-BACKUP/server-backup/VOSTRO
/scripts/

rsync -e "ssh" -avz --progress ~/wallpapers/ username@ip-address-remote:/media/hdd/Multimedia/wallpapers/
echo Finished Syncing to remote Mediaserver-
echo ...............................................bac kup finished

save & exit the script e.g: backup-script.sh

Using SSH without using password everytime you backup, do following:
You need to add id_rsa.pub key to remote machine's .ssh:
On local machine generate ssh key:

$ ssh-keygen and keep pressing enter till it finishes.


Then copy on remote machine use SCP command to copy the key over:
$ scp user@remotemachine:/home/remote-user/.ssh/id_rsa.pub .
Append to authorized_keys2 on local machine currently logged on to.
$ cat id_rsa.pub >> /home/user/.ssh/authorized_keys2
$ rm id_rsa.pub

To run the backup-script.sh -->
$ sh backup-script.sh

Here's a simple but good one to help you find the name of a command:


ls /usr/bin | grep "searchterm"Or for root commands


ls /usr/sbin | grep "searchterm"
If the command you want to find begins with "searchterm", you can just use tab-completion to do the search by entering the the search term, and then hitting tab twice to see a list of commands that begin with your search term, for example:

user@ubuntu-computer:~$ wh <--press TAB twice and get:
whatis which whiptail whoami
whereis while who whoi
Of course tab-completion will search all paths in your $PATH, so if you specifically want to search /usr/bin or /usr/sbin, then your method would work. Also, if you want to search for "update-grub" by entering "grub", you would have to use something like your method since the tab completion would only find commands that start with "grub", like "grub-install". :)

My cheat sheet is quite obvious.
