If you tend to forget which branch you're working on, this incantation adds (and colors) the branch name to the prompt. export PS1="[\u@\h\$(if [ -d CVS ]; then if [ -e CVS/Tag ]; then cat CVS/Tag \| sed -e 's/^T/ /' \| sed -e 's/^N/ /' \| sed -e 's/^D/ Date /' \| sed -e 's/_BRANCH/\[\033]12;blue\007\]/'; else echo ' \[\033]12;black\007\]MAIN' ; fi; else echo ' \[\033]12;black\007\]' ;fi) \W]\\$ "
