Hi,On my way to elapsed time in a bash script, I created the do_chrono command. It pumps the elapsed time to stdout.So if I do: a=do_chrono and then: $a I get: 0:3:19. Problem: I can't use that $a anywhere, e.g. if I say: echo $a I would expect to see 0:3:19 again, but I don't, it says do_chrono How do I use that $a in command parameters, like logger?
So this is the way it works now: #!/bin/bash a=do_chrono # elap to stdout $($a) &> /dev/null # Suppress output 1st call clears the chronometer(1) sleep 1 logger -t do_hibernate_prep =before sleep 4 $($a) # elap since (1)(2) sleep 4 logger -t do_hibernate_prep =after sleep 4 $($a) # elap since (2) exit 0 Produces:Sep 29 09:21:27 debian do_hibernate_prep: =do_hibernate_prep before sleep 4 0:0:1.30 Sep 29 09:21:31 debian do_hibernate_prep: =do_hibernate_prep after sleep 4 0:0:4.30
There probably are better ways of doing it. Thanks for the answers, couldn't find that in the guide... H
