It is sometimes desirable to run a command after n seconds has passed e.g. to run a command after the approximate time taken for deploy pipeline to complete.
Scheduling the command for a couple of minutes’ time allows me to progress to other tasks – thus clearing it off my list – or walk away from my desk, and not need to worry about running the script manually.
The Sleep Command
This command will pause for NUMBER seconds.
Syntax: sleep <number of seconds>.
To use the sleep command before running a script, use as follows:
sleep <seconds> && <your script>
Example: To run php my-script.php after 10 seconds of waiting, the following command would be used:
sleep 10 && php my-script.php
