Which file specifies the user accounts that can NOT submit jobs via at or batch? (Provide the full path and filename)

Show Suggested Answer Hide Answer
Suggested Answer: A

The /etc/at.deny file specifies the user accounts that can NOT submit jobs via at or batch. The format of the file is a list of usernames, one on each line. Whitespace is not permitted. The superuser may always use at. If the file /etc/at.allow exists, only usernames mentioned in it are allowed to use at.If /etc/at.allow does not exist, /etc/at.deny is checked12.The at and batch commands use the files /usr/lib/cron/at.allow and /usr/lib/cron/at.deny to restrict usage on some systems3.Reference:

at.allow(5) - Linux man page

I feel like it’s `/etc/at.deny`, but I could be confusing it with another configuration file.

I might be mixing it up, but isn't there also a `batch.deny` file? I can't recall the exact path though.

I remember practicing a similar question, and I think the answer is `/etc/at.deny`. It makes sense for user permissions.

I think the file is called `at.deny`, but I'm not entirely sure about the path. Was it `/etc/`?
