[NTLUG:Discuss] what does 'HUP' mean?

[m m]

Hi all:

A vety stupid question: what does 'HUP' mean?
please see the following, if not you are clear what I am ask.

"... into ~alias/.qmail-uucp-default. (For some UUCP software you will need
to use -d instead of -df. Also, you may need to insert a space between
-a and "$SENDER" for bounces to work properly.) If qmail-send is
running, give it a HUP."

I am configuring the qmail. that paragraph was copied from q-mail FAQ.

Thank you.
