How to lookup a user GUID

/in /by

You can lookup a users’s GUID using WorkGroup Manager, but what fun is that?

Here are just a few ways you can lookup a GUID

Lookup a single user: 10.7 & 10.8 Only: 

sudo /Applications/Server.app/Contents/ServerRoot/usr/bin/cvt_mail_data -i bobsmith

How handy it would be to have a list of all users and their GUID? 

dscl /Search -list /Users GeneratedUID

Above returns all of the sytem users, its cleaner if we omit them: 

dscl /Search -list /Users GeneratedUID | grep -v '^_'
