Script: Convert GroupWise addressbook to CSV
With a bunch of new employees, I got tired of not having an up-to-date contacts list in gmail, so I exported our GroupWise address book (it saved with a .NAB extension) and wrote a script to get the entries into CSV format to import to gmail. Thankfully, if a contact exists in gmail, it doesn’t get duplicated; if you add more information, it is added to the existing contact.
There was some crud in my file–generic system emails like “admissions”–but these were all at the top and were easy enough to delete by hand.
The script uses grep and awk. As they say, YMMV.
