Edit Question
Title
Body
I'm attempting to speed up a collection of scripts that invoke subshells and do all sorts of things. I was wonder if there are any tools available to time the execution of a shell script and its nested shells and report on which parts of the script are the most expensive. For example, if I had a script like the following. #!/bin/bash echo "hello" echo $(date) echo "goodbye" I would like to know how long each of the three lines took. time will only only give me total time for the script. bash -x is interesting but does not include timestamps or other timing information.
