.SH NAME
atd \- run jobs queued for later execution
.SH SYNOPSIS
.B atd
.RB [ -l
.IR load_avg ]
.RB [ -b
.IR batch_interval ]
.RB [ -d ]
.RB [ -s ]
.SH DESCRIPTION
.B atd
runs jobs queued by
.BR at(1) .
.PP
.SH OPTIONS
.TP 8
.B -l
Specifies a limiting load factor, over which batch jobs should
not be run, instead of the compile-time choice of @LOADAVG_MX@.
For an SMP system with
.I n
CPUs, you will probably want to set this higher than
.IR n-1.
.TP 8
.B -b
Specifiy the minimum interval in seconds between the start of two
batch jobs (60 default).
.TP 8
.B -d
Debug; print error messages to standard error instead of using
.BR syslog(3) .
.TP 8
.B -s
Process the at/batch queue only once.
This is primarily of use for compatibility with old versions of
.BR at ;
.B "atd -s"
is equivalent to the old
.B atrun
command.
A script invoking
.B "atd -s"
is installed as
.B @prefix@/sbin/atrun
for backward compatibility.
.SH FILES
.I @ATJBD@
The directory for storing jobs; this should be mode 700, owner
@DAEMON_USERNAME@.
.PP
.I @ATSPD@
The direcotry for storing output; this should be mode 700, owner
@DAEMON_USERNAME@.
.SH "SEE ALSO"
at(1), atrun(1), cron(1), crontab(1), syslog(3)
.SH BUGS
The functionality of 
.B atd
should be merged into
.BR cron(1) .
