A few years ago I setup a cron job to automatically ping a URL every minute as part of a monitoring system (that's oversimplification, but it'll do for this question). Because I'm a horrible person, I didn't document this anywhere.
Today, years later, I started having trouble with the application on the other end of the URL that's being pinged. I fixed it, but then realized, I have no idea where this cron job is coming from.
Is there a way to quickly search through or cat out all the crontabs on a particular system? I have root access so permissions aren't a problem. I've only ever been a user of
cron, I've never looked too deeply at its implementation, but my *nix instincts say there has to be a group of text files somewhere that hold all the crontabs. I just don't know where they'd be, and if I dug into it I'd be afraid of finding some, but not all of them, or missing some weird nuance of the system
Also, I realize with root access I could
- Get a list of all the users in the system
suas a user
- Repeat with all the users
but I'm looking for something a little less manual (and looking to learn something about cron's implementation)
