I have a user on my linux server who has sudo. I want to edit the crontab of another user. I'm new to this though and don't understand what the man pages are telling me yet.

Man crontab tells me I can use this format for the crontab command:

crontab [ -u user ] { -l | -r [ -i ] | -e }

But what does that mean? I want to edit the crontab of a user named jake

so I tried

crontab jake -e
crontab [jake] -e
crontab [-u jake] -e

And I get the same error every time: "usage error: no arguments permitted after this option"

So what do I type in to edit jake's crontab?

    The [ -u user ] means that you can optionally say -u user. I would've expected to see user either in italics (when typeset) or as <user> to indicate that it's not the literal string "user" you need to give,

Try

crontab -e -u jake

You will need to be root for this to work.

    sudo crontab -e -u jake would work without being root, and gets logged. Could also su jake and then do crontab -e but sudo much better.

  • @dunxd su doesn't work with disabled users or users without login shell. Like www-data is not a user you can switch to on many systems, yet this user has cronjobs to do.

you need sudo/root to edit any of crontab

    On many systems you can edit your own crontab without sudo/root.

  • @JennyD AFAIK if you have not add user entry in following file it wont work. # vi /etc/security/access.conf

    There are many varieties of unix, and many flavours of linux. Blocking crontab from regular users does not happen in all of them.

    How is this an answer? The OP already specified he has sudo.
