How can I get the correct user in a mail filter in CVS loginfo?

Question

I have a single CVS user (cvs) on my Unix box and I map all CVS users to this user via CVSROOT/passwd. When I do this, all mails are sent by the user cvs. I'd like to show the name of the committer in the mail subject (or even as the sender of the mail).

Is there any other way than creating a real Unix user?

Answer 1

CVS will put the commit user name into the variable $USER which you can use in the file loginfo to call your mail filter.
