DESCRIPTION
|
|
|
|
At prepares a file to be executed later at the specified time by creating
|
|
a special entry in /usr/spool/at. The program atrun should be started
|
|
periodically, for example, every minute by cron. Atrun checks to see if
|
|
any files in /usr/spool/at should now be run, and if so, it runs them and
|
|
then puts them in /usr/spool/at/past. The name of the file created in
|
|
/usr/spool/at by at is YY.DDD.HHMM.UU (where YY, DDD, HH, and MM give the
|
|
time to execute and UU is a unique number). Note that when the command
|
|
runs, it will not be able to use stdin or stdout unless specifically
|
|
redirected. In the first example above, it might be necessary to put
|
|
>/dev/log on some lines in the shell script myfile. The same holds for
|
|
the commands typed directly to at.
