That assumes the highest UID number has a login shell...

This also does not tell me how useradd knows that on this system at this time the highest UID assigned to a user is 20015. It will assign 20016 to the next user even though some dim bulb gave a use a UID of 4294967294 (how the hell that user can log in with a UID out of range is beyond me unless it gets truncated)... I have been able to use things like these 2 examples (cat /etc/passwd | cut -d: -f3 | sort -n | tail -2 | head -1 in this case) but I want to get the next UID from the system not by parsing /etc/passwd John
