atd8
Run jobs queued for later execution
Usage
atd [-l
load_avg]
[-b
batch_interval]
[-d]
[-f]
[-s]
Overview
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 0.8. 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
atdin 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 oldatruncommand.
Warning
atd won't work if its spool directory is mounted via NFS even if no_root_squash is set.
Files
/var/spool/atd The directory for storing jobs; this should be mode 700, owner daemon.
/var/spool/atd 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.
Releases
17 releases since Debian 1.3 (Bo); the text changed 9 times.
