Need to quickly see a list of all cron jobs on a computer? You can easily see all scheduled cron jobs by using the crontab command, and seeing cron data works the same on Mac as well as Linux and most other unix environments too.
Perhaps you have a script or task running and you’re trying to track it down, or perhaps you’re just curious and want to show all crontab for any other reason. Read on to learn how to show all cron jobs for all users, as well as for specific users on a computer.
How to Show All Cron Jobs
At the Terminal or command line, enter the following command syntax:
crontab -l
Hit return to see a list of all cronjobs.
How to List All Cron Jobs for Specific User
You can also check specific users crontab with the following command syntax:
crontab -l -u USERNAME
Again hit return to see a list of all cron jobs and crontab entries for a particular user.
This is obviously aimed at advanced users, and if you don’t know what cron is you’re probably not the target for this particular article. Of course some explanation may be helpful for the curious, so in short; cron allows for automation of processes from the command line, and scanning through crontab can be helpful if you are aiming to track down startup and login scripts, though for most Mac users they’ll use Login Items instead from the GUI.
