If you want to add an interval before executing the cron the next time you can add a sleep     for i in  1  100    do echo  i  amp  amp  curl  http   URL      tmp output log  amp  amp  sleep 120  done

for i in  seq 1 20   do curl http   url  done   Or if you want to get timing information back  use ab   ab -n 20 http   url

You could use URL sequence substitution with a dummy query string  if you want to use CURL and save a few keystrokes    curl http   www myurl com   1-20    If you have other query strings in your URL  assign the sequence to a throwaway variable   curl http   www myurl com  myVar 111 amp fakeVar  1-20    Check out the URL section on the man page  https   curl haxx se docs manpage html
