Run a command at a specific time

Question

I\'m trying to run a command at a specific time. I\'ve looked at the \"at\" command, but I don\'t know how to get it working...

Here\'s what I do:

at 184         


        

Answer 1

In bash or zsh you can say

at 1843 <<< 'php /run/this/script.php'

Failing that, you need to use a here document:

at 1843 <

You might also want to look into cron for regularly scheduled jobs; the crontab entry would look like

43 18 * * * php /run/this/script.php

(EDIT: whoops, helps to recall which version of at. I think that may have been a local mod.)
