I have a shell command that I would like to time (e.g., a curl query). I don't want to time it once, but instead many times, so that I can get an empirical distribution of the execution time. How can I do so?

I'm guessing that I could write some program any language to loop around the time program, but I was hoping for a more off-the-shelf solution.

Would something like this work for you?

for f in `seq 10`
do
    time curl www.google.com
done

  • Thanks I was hoping for something a bit more advanced e.g. providing empirical distribution statistics such as mean and standard deviation. – Franck Dernoncourt Oct 27 '20 at 2:37
  • You could pipe it into a file and do do some fancy greps and cuts and stuff? – Chai Ang Oct 27 '20 at 6:26
  • Yes. I was hoping for a more off-the-shelf solution since that seemed to me to be a quite common need, but perhaps it doesn't exist and indeed we have to code it ourselves :) – Franck Dernoncourt Oct 27 '20 at 6:30
