I have a similar section in my .bashrc via a somewhat hackish loop (or two): ESC=$'\x1b' # Terminal color escapes colornames=(BLACK RED GREEN YELLOW BLUE MAGENTA CYAN) for i in ${!colornames[@]}; do eval "${colornames[$i]}=\"${ESC}[3${i}m\"" eval "BG${colornames[$i]}=\"${ESC}[4${i}m\"" done # There are holes in this sequence, so it doesn't loop nicely BOLD="${ESC}[1m" DARK="${ESC}[2m" UNDERLINE="${ESC}[4m" BLINK="${ESC}[5m" INVERSE="${ESC}[7m" RST="${ESC}[m" styles=(BOLD DARK UNDERLINE BLINK INVERSE RST) # and the PS1-safe versions of the above for i in ${colornames[@]} ${colornames[@]/#/BG} ${styles[@]}; do eval "PS$i=\"\\[\$$i\\]\"" done Having color escapes in shell variables comes in handy from time to time (like faking 'colordiff' with sed).
