It's probably worth remembering the "vipw" utility, which is the safest 
way to edit passwd file directly, like we used to in the old days when 
it was a single plain text file. It sets and removes the appropriate 
locks and rebuilds the hidden version after doing some sanity checks on 
your edits.
