atd (8) - Linux Man Pages
atd: run jobs queued for later execution
NAMEatd - run jobs queued for later execution
SYNOPSISatd [-l load_avg] [-b batch_interval] [-d] [-f] [-s]
DESCRIPTIONatd runs jobs queued by at(1).
- 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.
- Specify the minimum interval in seconds between the start of two batch jobs (60 default).
- Debug; print error messages to standard error instead of using syslog(3). This option also implies -f.
- Run atd in the foreground.
- 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.
WARNINGatd won't work if its spool directory is mounted via NFS even if no_root_squash is set.
FILES/var/spool/at The directory for storing jobs; this should be mode 700, owner root.
/var/spool/at/spool The directory for storing output; this should be mode 700, owner root.
BUGSThe functionality of atd should be merged into cron(8).
