Coloring the Mac Terminal
Adding colors to ls
and tree
Enabling Colors
Edit ~/.bash_profile
or ~/.profile
and add the following two lines:
export CLICOLOR=1
export LSCOLORS=ExFxCxDxBxegedabagacad
you can use this if you are using a black background:
export LSCOLORS=gxBxhxDxfxhxhxhxhxcxcx
LSCOLORS="ExGxBxDxCxEgEdxbxgxcxd"
will emulate the default colouring on the linux ls command.
Making it permanent
You can add
alias ls='ls -Gp'
alias tree="tree -C"
to your ~/.bash_profile
to ALWAYS get colored ls
and tree
output.
-G
enables colorized output and the -p
adds a slash after each directory. the -C
turns on colorization for the tree command.
Customizing Colors (Mac)
The format is as follows: LSCOLORS=ExFxCxDxBxegedabagacad
LSCOLORS needs 11 sets of letters indicating foreground and background colors.
- directory
- symbolic link
- socket
- pipe
- executable
- block special
- character special
- executable with setuid bit set
- executable with setgid bit set
- directory writable to others, with sticky bit
- directory writable to others, without sticky bit
The possible letters to use are:
# COLORS
a black
b red
c green
d brown
e blue
f magenta
c cyan
h light grey
# BOLD CLOLORS
A block black, usually shows up as dark grey
B bold red
C bold green
D bold brown, usually shows up as yellow
E bold blue
F bold magenta
G bold cyan
H bold light grey; looks like bright white
# DEFAULT
x default foreground or background
place | key | foreground | background | meaning |
---|---|---|---|---|
1 | directory | E | x | bold blue with default background for directories |
2 | symlink | F | x | bold magenta with default background for symlinks |
Note: at this point i believe that you can not specify colors based on file extensions (for example, pink for image files extension like .jpeg,.jpg,.png or brown for code file extensions like .html, .js, .php etc.) You can do that in the GNU version of ls though, so i think that one is more powerful. Plus GNU ls has a better color specifying format in the form of LS_COLORS="di=01;90:ow=01;90"
adding colors to grep
matches
add the following to ~/.bash_profile
# Tell grep to highlight matches
export GREP_OPTIONS='--color=auto'
adding colors to common logfiles
brew install grc
echo 'source "`brew --prefix grc`/etc/grc.bashrc"' >> ~/.bash_profile
source ~/.bash_profile
