atd ? run jobs queued for later execution |
atd [-l load_avg] [-b batch_interval] [-d] [-s] |
atd runs jobs queued by at(1). |
-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 |
Specifiy 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. |
atd won’t work if its spool directory is mounted via NFS even if no_root_squash is set. |
/var/spool/at The directory for storing jobs; this should be mode 700, owner daemon. /var/spool/at/spool The direcotry for storing output; this should be mode 700, owner daemon. /etc/at.allow, /etc/at.deny determine who can use the at system. |
at(1), atrun(1), cron(8), crontab(1), syslog(3), at.deny(5), at.allow(5). |
The functionality of atd should be merged into cron(8). |
