Hi,
I have to combine several Unix password files and remove any duplicate
accounts - putting this into LDAP.
I have the following code that will remove any duplicate whole lines but
I need to remove lines only if the first field of the password file is a

This should work
perl -ne 'print unless $h{(split/:/)[0]}++'
