If you want to be certain that a file has been transferred, or if you want someone at the remote site to know that the file has arrived, you can use the -m and -n options on the uucp command, or the -m option on the uuto command.

• With uucp -m or uuto -m, as soon as the file is successfully transferred, you receive a mail message. You can use mailx to read the message. The first line describes the file transfer request, and the second line describes the result. For example, it might look like this:

  REQUEST: home!/usr/spool/uucppublic/memo1.txt north!/usr/spool/uucppublic/memo1.txt
  (SYSTEM north) copy successful

• With uucp -n name, if you are transferring a file to a remote site, you can specify the login name of the person at the remote site to be notified when the file is transferred. That person can read the notification message using mailx.
