The lines are ANSI escape sequences to get the colors. Here's a pretty good thorough explanation of what you can do in a prompt: http://www.faqs.org/docs/Linux-HOWTO/Bash-Prompt-HOWTO.html One thing to not forget is to make sure you surround all these with the special sequence saying to not count these characters as taking up room on the prompt line by using the special "\[" and "\]" sequences to begin and end each of them. Otherwise, bash gets confused and will wrap lines early. Note in the above link, how the colors are bracketed by these: local GRAY="\[\033[1;30m\]" local LIGHT_GRAY="\[\033[0;37m\]" local CYAN="\[\033[0;36m\]" local LIGHT_CYAN="\[\033[1;36m\]" local NO_COLOUR="\[\033[0m\]" (\033 and \e are equivalent). -- Jonathan Arnold (mailto:[EMAIL PROTECTED]) Daemon Dancing in the Dark, an Open OS weblog: http://freebsd.amazingdev.com/blog/ UNIX is user-friendly.
