# at\_allow(5)

determine who can submit jobs via at or batch

## NAME

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

## DESCRIPTION

The */etc/at.access* and */etc/at.deny* files determine which user can submit commands for later execution via **[at(1)](/at/1.md)** or **[batch(1)](/batch/1.md)**.

The format of the files 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 checked.
