generate user list then append emal address to end

[phymen]

Hello:

Been trying to develop a script with a list of user names from our Sun mailserver, with Solaris 10 and Postfix. I had the script collect all the home directories in /home then dump to a file and then did vi +:/%s/&/\@domain.com/g which works but then shell hangs and when I break out of the process vi is waiting for the :wq input. I've looked at sed, awk and cat as alternatives, is there another way to accomplish this? Once this file is generated I'll want to do an include: reference in /etc/postfix/aliases then restart Postfix to send out the email to all of our customers.

Thanks for any suggestions,
Phymen

Is the list of home directories more reliable than /etc/passwd in this scenario for some reason?

This should be equivalent to what you're trying to do in vi:

sed 's/&/\@domain.com/g' inputfile > outputfile

However if you prefer you could also do it with vi to edit the file in place using:

vi +'%s/&/@domain.com/g|wq' inputfile

As you see you can separate multiple vi commands using |.
