NAME

6       atd - run jobs queued for later execution
7

SYNOPSIS

9       atd [-l load_avg] [-b batch_interval] [-d] [-s] [-n]
10

DESCRIPTION

12       atd runs jobs queued by at(1).
13

OPTIONS

15       -l      Specifies  a limiting load factor, over which batch jobs should
16               not be run, instead of the compile-time choice of 0.8.  For  an
17               SMP  system  with  n  CPUs,  you will probably want to set this
18               higher than n-1.
19
20       -b      Specify the minimum interval in seconds between  the  start  of
21               two batch jobs (60 default).
22
23       -d      Debug;  print error messages to standard error instead of using
24               syslog(3).
25
26       -s      Process the at/batch queue only once.  This is primarily of use
27               for compatibility with old versions of at; atd -s is equivalent
28               to the  old  atrun  command.   A  script  invoking  atd  -s  is
29               installed as /usr/sbin/atrun for backward compatibility.
30
31       -n      Don't fork option.
32

WARNING

34       atd  won't  work  if  its  spool  directory  is mounted via NFS even if
35       no_root_squash is set.
36

FILES

38       /var/spool/at The directory for storing jobs; this should be mode  700,
39       owner root.
40
41       /var/spool/at/spool  The  directory  for storing output; this should be
42       mode 700, owner root.
43
44       /etc/at.allow, /etc/at.deny determine who can use the at system.
45

SEE ALSO

BUGS

51       The functionality of atd should be merged into cron(8).
