make grep colorful
Your grep searches can be colored on matches. You can set it in your shell profile. The color is set by the environment variable GREP_COLOR. Add this to your shell preferences (eg. .cshrc .bashrc .profile):
# color to user for grep matches setenv GREP_COLOR '0;32' #green setenv GREP_OPTIONS '--color=auto'
Or without these settings in the shell, the command for grep is aliased to that it asks for colored output.
grep --color=always
