NAME

6       atd - run jobs queued for later execution
7

SYNOPSIS

9       atd [-l load_avg] [-b batch_interval] [-d] [-f] [-n] [-s]
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).  This option also implies -f.
25
26       -f      Run atd in the foreground.
27
28       -s      Process the at/batch queue only once.  This is primarily of use
29               for  compatibility with old versions of at; -n Append the host‐
30               name of the system to the subject of the e-mails sent by atd.
31
32       atd -s  is equivalent to the old atrun command.
33

WARNING

35       atd won't work if its spool  directory  is  mounted  via  NFS  even  if
36       no_root_squash is set.
37

FILES

39       /var/spool/at  The directory for storing jobs; this should be mode 700,
40       owner root.
41
42       /var/spool/at/spool The directory for storing output;  this  should  be
43       mode 700, owner root.
44
45       /etc/at.allow, /etc/at.deny determine who can use the at system.
46

SEE ALSO

48       at(1), at.deny(5), at.allow(5), cron(8), crontab(1), syslog(3).
49

BUGS

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