crontab file of a specified user.

root can do this exactly like you specified.

Hello,

but my question is how wecan do that?

[Patrick Wallek]

The only user that can edit a different users crontab is root.

If you want usera to be able to edit the crontab file for userb then you will have to use something like 'sudo' to allow that.
