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.
-n
Don't fork option.
WARNING
atd
won't work if its spool directory is mounted via NFS even if
no_root_squash
is set.
