AWK: extract e-mail addresses from a Unix passwd file

All users of our CIP (computer) pool have an e-mail address of login@cip.iff.lmu.de.

awk -F: '{print $5" <" $1 "@" mh  ">"}' mh="cip.ifi.lmu.de" ./passwd > mail_list.txt

Output:

Programmierpraktikum Prgprakt <pp99@cip.ifi.lmu.de>
Programmierpraktikum Prgprakt <prgprakp@cip.ifi.lmu.de>
