If you have a new distribution of Linux, do these modifications to these files in your home directory. They take effect after next login.
~/.bashrc: alias ls="ls ‐‐color" ~/.cshrc: alias ls 'ls ‐‐color'
You may also want to do an «
eval `dircolors $HOME/.colourrc` », to get your own colours. This file is created with «
dircolors -p >$HOME/.colourrc » and is well commented for further editing.
