The timer_stop function also has the job of converting the timer into a human-readable format, and it’s probably messier than it needs to be. I’m no developer, though, so this is what Past Lee settled on after a few hours of searching through examples. Doing it in fish for folks like me That’s for bash when I’m ssh’d into one of my Linux hosts, but I run fish on MacOS. I have a separate fish function for getting the same results there, complete with gross hacks for turning the measurement into human-readable form. I made this code, and I am unapologetic. Witness my cobbled-together StackOverflow-sourced kludge. function fish_prompt --description 'Write out the prompt' # Save the last status set -l last_status $status # Calculate the command duration if available set -l cmd_duration "" if set -q CMD_DURATION # Convert milliseconds to microseconds for more precise comparison set -l duration_us (math "$CMD_DURATION * 1000") # Calculate different time units set -l us (math "$duration_us % 1000") set -l ms (math "floor($duration_us / 1000) % 1000") set -l s (math "floor($duration_us / 1000000) % 60") set -l m (math "floor($duration_us / 60000000) % 60") set -l h (math "floor($duration_us / 3600000000)") # Format duration string if test $h -gt 0 set cmd_duration (string join '' "(" $h "h" $m "m)") else if test $m -gt 0 set cmd_duration (string join '' "(" $m "m" $s "s)") else if test $s -ge 10 set -l fraction (math "floor($ms / 100)") …
