How to make (a gumstix say) show colors for ls (assuming your login shell is bash). Edit ~/.bashrc and ~/.bash_profile to match these files:
Make sure your shell is bash (if it’s not, you can change it in /etc/passwd):
root@overo:~# echo $SHELL /bin/bash
In ~/.bashrc:
root@overo:~# cat .bashrc export LS_OPTIONS='--color=auto' eval `dircolors` alias ls='ls $LS_OPTIONS'
In ~/.bash_profile:
root@overo:~# cat .bash_profile source ~/.bashrc
