faxrm removes queued fax jobs. Call with a list of jobIDs to remove specific jobs. Call with no job IDs to be asked interactively about all jobs you own (if run by root, all jobs). For job-id, use the strings returned by faxq(1) (e.g. F000015), without the ``/JOB'' extention.
If you are not the owner of the fax job (as per the `user xyz' statement inside the JOB file), you are not allowed to remove the fax job. Only root is permitted to remove another user's faxes.
If the job is locked (most likely because sendfax(8) is active sending it), faxrm doesn't attempt to remove it. Instead, it prints a warning message on stderr and goes on to the next job.
