atd

ATD(8)							      System Manager's Manual							    ATD(8)

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).
