       at.allow, at.deny - determine who can submit jobs via at or batch


       The  /etc/at.allow  and  /etc/at.deny  files  determine which user can submit commands for
       later execution via at(1) or batch(1).

       The format of the files is a list of usernames, one  on  each  line.   Whitespace  is  not

       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 checked, every username not mentioned in
       it is then allowed to use at.

       An empty /etc/at.deny means that every user may use at.

       If neither exists, only the superuser is allowed to use at.


       at(1), cron(8), crontab(1), atd(8).
