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).
