Bash color shell on Mac?

Question

How can you make a bash shell list executable files in a different color than non-executable files?

I've tried editing ~/.bashrc to contain the following line (it's otherwise empty):

 LS_OPTIONS='--color=auto'

But it's not working. What am I doing wrong? I'm working on Mac OS X.

Answer 1

BSD ls works a bit differently

alias ls='ls -G'

should work.

And this isn't bash coloring, it is ls doing the colorization. When bash does a file list (try echo * in a directory) there is no way to colorize. Typing ls -G would work in any shell, though a shell (like bash) that has aliases makes it easier.

Answer 2

The problem is that OS X doesn't have GNU ls; while its ls does support file name coloring, it can only do so by the type of file (file, directory, symlink, device special file, fifo, socket...). Install coreutils from Fink/MacPorts/HomeBrew, then use alias ls='gls --color=auto'.

Answer 3

To turn on colour output from the ls command without having to create an alias to ls or download any additional software, add the following to your ~/.bash_profile:

# Terminal colours
export CLICOLOR=1
export LSCOLORS=ExFxCxDxBxegedabagacad

If you don't like those colours you can use this ls color generator to customize that color list to your liking.

You'll need to do:

source ~/.bash_profile

After making any changes for them to take effect in your existing shell.

Answer 4

On the Mac, you need to use

export CLICOLOR=1

I put that in the .bash_profile. However, I prefer Rich Homolka's solution to alias ls with -G flag. If you want to customize the colors:

man ls

and search for LSCOLORS

Answer 5

bash is only a shell, it does not list files. It executes commands, such as ls.

The --color option (and long options in general) is specific to the version of ls from GNU coreutils, which comes with most Linux distributions. On the other hand, Mac OS X has BSD roots and uses the BSD version of ls which does not support colouring.
