One option that is missing that I really thing is useful is wincolour=$yellow errorcolour=$red # To provide a coloured version of $?, wrapped in (). Used in PS1 pretty_exit_code(){ LAST_COMMAND_STATUS=$? if [ $LAST_COMMAND_STATUS = 0 ]; then echo -e "$wincolour($LAST_COMMAND_STATUS)$black"; else echo -e "$errorcolour($LAST_COMMAND_STATUS)$black"; fi } Which just provides the exit code of the last command, but coloured differently for failure or success.

Just added exit status to the page. Thanks for the suggestion.

Interesting. I've been using $PIPESTATUS at the start of my prompt for a while now.

  I use this, which allows a similar effect but is enabled for PIPESTATUS, and also does some good things for eterm and screen. PIPESTATUS_REGEX="^ +$" # check to see if any of the pipe statuses don't start with 0 # ${_CMD_PIPESTATUS[@]#0} results in null if they all do _PIPESTATUS=" _CMD_PIPESTATUS=(\${PIPESTATUS[@]}) if [[ \"\${_CMD_PIPESTATUS[*]#0}\" && ! \"\${_CMD_PIPESTATUS[*]#0}\" =~ \$PIPESTATUS_REGEX ]] then _RES_STR=\" [\${_CMD_PIPESTATUS[*]}]\"; else _RES_STR='' fi" export PROMPT_COMMAND="$_PIPESTATUS; $PROMPT_COMMAND" if [[ $TERM = screen || $_TERM = screen ]]; then _RESET_PROMPT="\[\033k\033\\\\\]" else _RESET_PROMPT="" fi if [ $TERM = "eterm-color" ]; then # XXX: this is going to break things when you start # use $INSIDE_EMACS to test whether we should use \u? _ETERM_PROMPT="\[\033AnSiTu \u\012\033AnSiTc \w\012\033AnSiTh \H\012\]" else _ETERM_PROMPT="" fi export PS1="\n$_ETERM_PROMPT\[\033[32m\]\u@\h \[\033[33m\]\w\[\033[35m\]\$_RES_STR\[\033[0m\]\n${_RESET_PROMPT}\\$ " unset _RESET_PROMPT

    It's cool to also see the name of the signal that caused exit status > 128. Sadly this only fits in a tweet if it can assume the possible signal names are listed contiguously, which isn't so on 64-bit Linux these days. S=(`trap -l`);e(){ for N in ${PIPESTATUS[@]};do ((N>128))&&echo ${S[$((2*N-257))]}||echo $N;done;};trap $'echo "\e[41m Exit "`e`" \e[m"' ERR

      That's a great idea. I've rewritten my own version to use these signals instead of numbers where possible.
