NAME
atd - run jobs queued for later execution

SYNOPSIS
atd [-l load_avg] [-b batch_interval] [-d] [-f] [-s]

DESCRIPTION
atd runs jobs queued by at(1).

OPTIONS
-l Specifies a limiting load factor, over which batch jobs should
not be run, instead of the compile-time choice of 1.5. For an
SMP system with n CPUs, you will probably want to set this
higher than n-1.

-b Specify the minimum interval in seconds between the start of
two batch jobs (60 default).

-d Debug; print error messages to standard error instead of using
syslog(3). This option also implies -f.

-f Run atd in the foreground.

-s Process the at/batch queue only once. This is primarily of use
for compatibility with old versions of at; atd -s is equivalent
to the old atrun command.

WARNING
atd won't work if its spool directory is mounted via NFS even if
no_root_squash is set.

FILES
/var/spool/cron/atjobs The directory for storing jobs; this should be
mode 700, owner daemon.

/var/spool/cron/atspool The directory for storing output; this should
be mode 700, owner daemon.

/etc/at.allow, /etc/at.deny determine who can use the at system.

SEE ALSO
at(1), at.deny(5), at.allow(5), cron(8), crontab(1), syslog(3).

BUGS
The functionality of atd should be merged into cron(8).
