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. A script invoking atd -s is installed as /usr/sbin/atrun for backward compatibility.

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

BUGS

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