Here's what I'm currently rocking: 0 0:00:00 ~/Code/company/app$ First number is exit code of previous command, second is how long it took. Credit to https://unix.stackexchange.com/questions/252229/ps1-prompt-to-show-elapsed-time https://unix.stackexchange.com/questions/252229/ps1-prompt-t... for the last part. It's a bit ratchet: - I actually don't care about the exit code unless it was non-zero - It calculates the delta three times but I've been to busy to optimise it. prompt_command() { _PS1_now=$(printf '%(%s)T') PS1=$( printf "\n\$? \[\e%02d:%02d:%02d \n\[\033[01;34m\]\w\[\033[00m\]\$ " \ $(( ( _PS1_now - _PS1_lastcmd ) / 3600)) \ $(( (( _PS1_now - _PS1_lastcmd ) % 3600) / 60 )) \ $(( ( _PS1_now - _PS1_lastcmd ) % 60)) \ ) _PS1_lastcmd=$_PS1_now } PROMPT_COMMAND='prompt_command' _PS1_lastcmd=$(printf '%(%s)T')
