# at.allow(5)

determine who can submit jobs via at or batch

## NAME

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

## DESCRIPTION

The */etc/at.allow* 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.

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.

## SEE ALSO
