Howto: Add custom color to directory listings.

skoal · 09:28 PM

You ever fire up an xterm and perform an "ls" command? Sure you have! If so, did you ever wish that:

certain files would "stand out" with a custom color, and not the defaults?
you can add other filename extensions to the database with their own custom color as well?

Well, here's how...

NOTE: All commands to be entered in a terminal shell or changes made to a file are hilighted in red. You only need to cut/paste those items which are hilighted, the surrounding text is left for illustration purposes.

1. Edit the '.bashrc' file. You need to make a few small changes to the existing bash script.

(optional) Backup the file. Copy your existing '.bashrc' file in case you wish to restore it at a latter time. For example,
Code:
```
skoal@morpheus:///tmp $ cd && cp .bashrc .bashrc~
skoal@morpheus://~ $ ls .bashrc*
.bashrc  .bashrc~
```

Modify the file. Using your favorite text editor, open the file '~/.bashrc' and make the following changes hilighted in red (which should appear somewhere near the top of that file - line 17 if no prior alterations were made). You will basically be modifying one line and adding two more above it.

Code:

skoal@morpheus:///tmp $ gedit ~/.bashrc

and make these changes in the file,

Code:

# enable color support of ls and also add handy aliases
if [ "$TERM" != "dumb" ]; then
    [ -e "$HOME/.dircolors" ] && DIR_COLORS="$HOME/.dircolors"
    [ -e "$DIR_COLORS" ] || DIR_COLORS=""
    eval "`dircolors -b $DIR_COLORS`"
    alias ls='ls --color=auto'
    #alias dir='ls --color=auto --format=vertical'
    #alias vdir='ls --color=auto --format=long'
fi

(alternative to step 1.ii) Patch the file. Using the attched 'bashrc.patch' file, patch the current '~/.bashrc' file instead of cutting/pasting with an editor.

Code:

skoal@morpheus:///tmp $ bunzip2 bashrc.patch.bz2
skoal@morpheus:///tmp $ cp bashrc.patch ~
skoal@morpheus:///tmp $ cd && patch -p0 < bashrc.patch
patching file .bashrc
Hunk #1 succeeded at 19 (offset 5 lines).

2. Create the '.dircolors' file. The '.dircolors' file is created by using the 'dircolors' program. It will generate a default color scheme to be used with the "LS_COLORS" environment variable, which gives the colored output while using "ls".

Code:

skoal@morpheus:///tmp $ cd && dircolors -p > .dircolors

3. Edit the '.dircolors' file. Here is where you will be modifying/creating new color schemes to reflect your own unique style.

NOTE: Lines 34-41 within this file give you the color codes for three specific keys: attribute, text, and background. You can choose to use all three keys, or simply pick and choose only those keys you wish to apply. Look at some of the pre-defined ones you may already recognize as a good example to follow.

Modify existing color schemes. For example, I can't stand big bold blue directory listings, so I change the bold attribute from "01" to "00" (none) but keep the blue color. It will lighten things up a bit.
Code:
```
FILE 00         # normal file
DIR 00;34       # directory
LINK 01;36      # symbolic link.
```
or, change the "01" to an "07", making your debian packages really stand out!
Code:
```
.gz  01;31
.bz2 01;31
.deb 07;31
.rpm 01;31
.jar 01;31
```
which will "reverse" the red (31) foreground color - basically making it black text inside a red box! Whoa! Ugly but effective, no?
Create new color schemes. I like to program, yet for some reason, there are no default colors for well known language extensions. I like my c/c++ source to show up as green and my header files as yellow. Here's how I added these extensions to the bottom of that file:
Code:
```
# audio formats
.ogg 01;35
.mp3 01;35
.wav 01;35

# programming languages
.c 00;32
.cc 00;32
.cpp 00;32
.h 00;33
```

4. Source the '.bashrc' file. In order for your changes to take effect within the current shell, you need to source the '.bashrc' file.

Code:

skoal@morpheus:///tmp $ cd && . .bashrc

** END of Howto **

and, just to see your handy work, look at these two environmental variables:

Code:

skoal@morpheus://~ $ set | grep 'DIR_COLORS\|LS_COLORS'
DIR_COLORS=/home/skoal/.dircolors
LS_COLORS='no=00:fi=00:di=00;34:ln=01;36:pi=40;33:so=01;35:do=01;35:bd=40;33;01:cd=40;33;01:or=40;31;01:ex=01;32:*.tar=01;31:*.tgz=01;31:*.arj=01;31:*.taz=01;31:*.lzh=01;31:*.zip=01;31:*.z=01;31:*.Z=01;31:*.gz=01;31:*.bz2=01;31:*.deb=01;31:*.rpm=01;31:*.jar=01;31:*.jpg=01;35:*.jpeg=01;35:*.gif=01;35:*.bmp=01;35:*.pbm=01;35:*.pgm=01;35:*.ppm=01;35:*.tga=01;35:*.xbm=01;35:*.xpm=01;35:*.tif=01;35:*.tiff=01;35:*.png=01;35:*.mov=01;35:*.mpg=01;35:*.mpeg=01;35:*.avi=01;35:*.fli=01;35:*.gl=01;35:*.dl=01;35:*.xcf=01;35:*.xwd=01;35:*.ogg=01;35:*.mp3=01;35:*.wav=01;35:*.c=00;32:*.cc=00;32:*.cpp=00;32:*.h=00;33:'

NOTE: These color changes will be preserved upon each reboot or login. If you wish to revert to the original color scheme, just delete the file '.dircolors' in your $HOME directory (or, alternatively, restore your backup file made in step 1.i).

Code:

skoal@morpheus:///tmp $ rm -f ~/.dircolors

NOTE: I've only tested this with a plain 'ole vanilla stock 'xterm'. I do not use gnome-terminal, kterm(?), or any other variants but it should work equally well with them. I do not use any file managers of any sort, so without some MIME associated icon staring me in the face, these colors really help. Using 'dircolors' is old as dirt, and I'm surprised no one else hadn't mentioned this yet. Am I the only one who thinks CLI+color > [insert favorite File Manager here]? Surely, I'm not alone. Or am I...

Thanx for the nice HOWTO!

By the way, to get syntax highlight on VI you can edit the "filetype.vim" file, located in /usr/share/vim/"vim version"/. Just change the line:

au BufNewFile,BufRead .dir_colors,/etc/DIR_COLORS setf dircolors

to

au BufNewFile,BufRead .dir_colors,.dircolors,/etc/DIR_COLORS setf dircolors

Alternatively you can name the file ".dir_colors" insted of ".dircolors".

VI rules!

Hi, I've tried applying the instructions from this somewhat dated Howto creating a .dircolors file in my home directory, modifing the ~$ .bashrc file and then sourcing it.
~$ . .bashrc
Errors occurred on two attempts after editing and then sourcing the bashrc file. One was something like unescaped fi the other was unexpected end of file at line 75.

Here is the original feisty bashrc code:
# enable color support of ls and also add handy aliases
if [ "$TERM" != "dumb" ]; then
eval "`dircolors -b`"
alias ls='ls --color=auto'
#alias dir='ls --color=auto --format=vertical'
#alias vdir='ls --color=auto --format=long'
fi

Here is the modified code I inserted:
# enable color support of ls and also add handy aliases

if [ "$TERM" != "dumb" ]; then

[ -e "$HOME/.dircolors" ] && DIR_COLORS="$HOME/.dircolors"

[ -e "$DIR_COLORS" ] || DIR_COLORS=""

eval "`dircolors -b $DIR_COLORS`"

alias ls='ls --color=auto'

#alias dir='ls --color=auto --format=vertical'

#alias vdir='ls --color=auto --format=long'

fi

I don't know if it's something I'm doing wrong or changes to Ubunutu Feisty making the code unworkable.

Unfortunately this tutorial didn't work for me (ubuntu gutsy gibbon), too. here is my .bashrc
perhaps someone knows the issue?

p.s. the last line I dropped in by myself.

thanx in advance!

For anybody battling with dircolors here is a great little shell-script that displays every available colour combination for you to select from.

To execute type bash ttycolors.sh

pdxvampire · 12:23 PM

dmgExP - That script is excellent, thank you! It saved me quite a bit of time in setting up dircolors for my various terminals, each of which has a different solid color background. No more guessing, just fired up that script and was able to see what would work instantly!

cooltoddy

I know its been over 4 years after this post was made, but am trying my luck. Can you help me with the attachment you are talking about.

Thanks

Help, I followed the instructions from skoal (Thank You skoal).
All my suffixes are changing to the correct color except for my
( .java, .c and .cpp ) suffixes. These suffixes are staying bright green.

I set .java to green 00;32 .c to brown 00;36 and .cpp to cyan 00;36

So when I type the ls command I would like to see:
$ls
foo.c foo.cpp foo.java

however what I see is:
$ls
foo.c foo.cpp foo.java

Is there anyway to be able to change these suffixes to the correct color?

Below is my .dircolors file and .bashrc file:

OOPS. I found the problem.
All excutables are bright-green .
Some how the .java , .cpp, and .c files had executable permissions.
When I took away the executable permissions by typing ( chmod ugo -x *.java etc.. )
the colors to my suffixes were the I wanted them.

Thanks again to skoal for the great instructions .

Code: skoal@morpheus:///tmp $ cd && dircolors -p > .dircolors 3. Edit the '.dircolors' file. Here is where you will be modifying/creating new color schemes to reflect your own unique style. NOTE: Lines 34-41 within this file give you the color codes for three specific keys: attribute, text, and background. You can choose to use all three keys, or simply pick and choose only those keys you wish to apply. Look at some of the pre-defined ones you may already recognize as a good example to follow. Modify existing color schemes. For example, I can't stand big bold blue directory listings, so I change the bold attribute from "01" to "00" (none) but keep the blue color. It will lighten things up a bit. Code: FILE 00 # normal file DIR 00;34 # directory LINK 01;36 # symbolic link. or, change the "01" to an "07", making your debian packages really stand out! Code: .gz 01;31 .bz2 01;31 .deb 07;31 .rpm 01;31 .jar 01;31 which will "reverse" the red (31) foreground color - basically making it black text inside a red box! Whoa! Ugly but effective, no? Create new color schemes. I like to program, yet for some reason, there are no default colors for well known language extensions. I like my c/c++ source to show up as green and my header files as yellow. Here's how I added these extensions to the bottom of that file: Code: # audio formats .ogg 01;35 .mp3 01;35 .wav 01;35 # programming languages .c 00;32 .cc 00;32 .cpp 00;32 .h 00;33 4. Source the '.bashrc' file. In order for your changes to take effect within the current shell, you need to source the '.bashrc' file. Code: skoal@morpheus:///tmp $ cd && . .bashrc END of Howto and, just to see your handy work, look at these two environmental variables: Code: skoal@morpheus://~ $ set \| grep 'DIR_COLORS\\|LS_COLORS' DIR_COLORS=/home/skoal/.dircolors LS_COLORS='no=00:fi=00:di=00;34:ln=01;36:pi=40;33:so=01;35:do=01;35:bd=40;33;01:cd=40;33;01:or=40;31;01:ex=01;32:.tar=01;31:.tgz=01;31:.arj=01;31:.taz=01;31:.lzh=01;31:.zip=01;31:.z=01;31:.Z=01;31:.gz=01;31:.bz2=01;31:.deb=01;31:.rpm=01;31:.jar=01;31:.jpg=01;35:.jpeg=01;35:.gif=01;35:.bmp=01;35:.pbm=01;35:.pgm=01;35:.ppm=01;35:.tga=01;35:.xbm=01;35:.xpm=01;35:.tif=01;35:.tiff=01;35:.png=01;35:.mov=01;35:.mpg=01;35:.mpeg=01;35:.avi=01;35:.fli=01;35:.gl=01;35:.dl=01;35:.xcf=01;35:.xwd=01;35:.ogg=01;35:.mp3=01;35:.wav=01;35:.c=00;32:.cc=00;32:.cpp=00;32:.h=00;33:' NOTE: These color changes will be preserved upon each reboot or login. If you wish to revert to the original color scheme, just delete the file '.dircolors' in your $HOME directory (or, alternatively, restore your backup file made in step 1.i). Code: skoal@morpheus:///tmp $ rm -f ~/.dircolors NOTE: I've only tested this with a plain 'ole vanilla stock 'xterm'. I do not use gnome-terminal, kterm(?), or any other variants but it should work equally well with them. I do not use any file managers of any sort, so without some MIME associated icon staring me in the face, these colors really help. Using 'dircolors' is old as dirt, and I'm surprised no one else hadn't mentioned this yet. Am I the only one who thinks CLI+color > [insert favorite File Manager here]? Surely, I'm not alone. Or am I... \\//_ Last edited by skoal; June 13th, 2005 at 09:28 PM..

agapito Just Give Me the Beans! Join Date: Nov 2005 Location: Lisbon, Portugal Beans: 75 Ubuntu 8.10 Intrepid Ibex	Re: Howto: Add custom color to directory listings. Thanx for the nice HOWTO! By the way, to get syntax highlight on VI you can edit the "filetype.vim" file, located in /usr/share/vim/"vim version"/. Just change the line: au BufNewFile,BufRead .dir_colors,/etc/DIR_COLORS setf dircolors to au BufNewFile,BufRead .dir_colors,.dircolors,/etc/DIR_COLORS setf dircolors Alternatively you can name the file ".dir_colors" insted of ".dircolors". VI rules!

ubz 5 Cups of Ubuntu Join Date: May 2007 Beans: 21 Ubuntu 7.10 Gutsy Gibbon	Re: Howto: Add custom color to directory listings. Hi, I've tried applying the instructions from this somewhat dated Howto creating a .dircolors file in my home directory, modifing the ~$ .bashrc file and then sourcing it. ~$ . .bashrc Errors occurred on two attempts after editing and then sourcing the bashrc file. One was something like unescaped fi the other was unexpected end of file at line 75. Here is the original feisty bashrc code: # enable color support of ls and also add handy aliases if [ "$TERM" != "dumb" ]; then eval "`dircolors -b`" alias ls='ls --color=auto' #alias dir='ls --color=auto --format=vertical' #alias vdir='ls --color=auto --format=long' fi Here is the modified code I inserted: # enable color support of ls and also add handy aliases if [ "$TERM" != "dumb" ]; then [ -e "$HOME/.dircolors" ] && DIR_COLORS="$HOME/.dircolors" [ -e "$DIR_COLORS" ] \|\| DIR_COLORS="" eval "`dircolors -b $DIR_COLORS`" alias ls='ls --color=auto' #alias dir='ls --color=auto --format=vertical' #alias vdir='ls --color=auto --format=long' fi I don't know if it's something I'm doing wrong or changes to Ubunutu Feisty making the code unworkable.

It saved me quite a bit of time in setting up dircolors for my various terminals, each of which has a different solid color background.

Some how the .java , .cpp, and .c files had executable permissions. When I took away the executable permissions by typing ( chmod ugo -x *.java etc.. ) the colors to my suffixes were the I wanted them. Thanks again to skoal for the great instructions . tmllvs
