Removing a process from the schedule

You can remove a scheduled process with the at command using the -r flag.

See the following example on how to use the at or atq command:

To remove a scheduled process, you must know its process number.
You can obtain the process number by using the at -l command or the atq command.
When you know the number of the process you want to remove, type the following:
```
at -r ProcessNumber
```

You can also use the smit rmat command to perform this task.
