Use dscl to write to file a list of user recordNames and MailAttribute

Hello All,

osx server 10.4

I'm attempting to export a list of user specific account keys to a file. So far I can export a list of user names:

A) dscl /LDAPv3/127.0.0.1 -list /Users >> aFile.txt

I can read the requested attributes for a single user:

B) dscl /LDAPv3/127.0.0.1 -read /Users/MyUser recordName MailAttribute >> aFile.txt

What I can't work out, due to my lack of Mac Terminal/Scripting knowledge, is how to export the recordName and MailAttribute keys for each user in the exported users list.

All help greatly appreciated.....

PS I don;t need the workgroup manager export as that has far too much "fluff" in it for my purpose.
