ATD(8) Linux Programmer's Manual ATD(8)
NAME
atd - run jobs queued for later execution
SYNOPSIS
atd [-l load_avg] [-b batch_interval] [-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 proba-
bly 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).
-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 dae-
mon.
/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).
