The at command allows programs to be scheduled at a certain time. The at command takes a time as its argument. After pressing return the commands to be executed can be entered, followed by a CTRL-D on an emty line.
The time can be specified in the form HH:MM
, followed by an
optional date in the form month name day of month, followed by
an optional increment. The increment is preceeded by a '+' followed by
a number or the special word next and one of the words:
minute[s], hour[s],
day[s], week[s],
month[s],
year[s].
To find out what jobs are scheduled with at we can run at -l. To remove jobs from the queue, we can run at -r followed by the jobs number gained from at -l.
