NAME
atd - run jobs queued for later execution
SYNOPSIS
atd
[-l
R load_avg ]
[-b
R batch_interval ]
[-d]
[-s]
DESCRIPTION
atd
runs jobs queued by
R 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
R 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
R syslog(3) .
-s
Process the at/batch queue only once.
This is primarily of use for compatibility with old versions of
R 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.
R /etc/at.allow ,
R /etc/at.deny
determine who can use the
at
system.
SEE ALSO
BUGS
The functionality of
atd
should be merged into
cron(8) .
