NAME

atd - run jobs queued for later execution

SYNOPSIS

atd [__-l__ ''load_avg'' [unrenderable node] [__-d__ [__-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

Specifiy 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)__.

-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.

BUGS

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