Editing At (command) (section)

====Examples====
A sample command to compile a [[C (programming language)|C]] program at 11:45 a.m. on January 31 would be:

<syntaxhighlight lang="console">
$ echo "cc -o foo foo.c" | at 1145 jan 31
</syntaxhighlight>
or
<syntaxhighlight lang="console">
$ at 1145 jan 31
at> cc -o foo foo.c
at> ^D #(press Control-D while at the beginning of a line)
</syntaxhighlight>

The '''<code>atq</code>''' program lists the currently queued jobs, while '''<code>atrm</code>''' removes jobs from the queue:
<syntaxhighlight lang="console">
$ atq
1234 2011-08-12 11:45 cc -o foo foo.c user
$ atrm 1234 
$ atq
$
</syntaxhighlight>

In some Unix-like computer [[operating system]]s, it uses a [[Daemon (computing)|daemon]], '''<code>atd</code>''', which waits in the background periodically checking the list of jobs to do and executing those at their scheduled time on behalf of '''<code>at</code>'''.
