screen -dmS 17secondjob perl -e 'while(1){`run the command`;sleep 17}'

Or, simpler, use watch:

watch -n 17 -p command

Make a wrapper to run command in the background (&) if the process runtime is greater than your interval.

This will not run the `command` in 17 seconds intervals. You need to take into account the amount of time that it takes to run it.

Ok. Whilst we're being anal:

screen -dmS 17secondjob perl -Mthreads -e 'while(1){threads->create(sub{`run the command`})->detach();sleep 17}'

Or just use watch.

Cool. I was unfamiliar with this command. Looks useful.

[eru → mike-cardwell]

Look for `watch -p'.
