System: NetBSD tnt 1.6 NetBSD 1.6 (PM8500wACARD6260wMX98715AEC) #0: Mon Apr 14 00:10:10 EDT 2003 root@tnt:/usr/src/sys/arch/macppc/compile/PM8500wACARD6260wMX98715AEC macppc
I ran `useradd --help` which didn't work as I expected, but failed
in such a way as to leave my password file locked. It also left me
uncertain as to how to unlock it; it would be nice if it both didn't
do this, and made a helpful comment about proceeding on foot in case
I'm supposing I just find and delete the pw_lock file, but do I need
to worry about anything being in an inconsistant state?

bash: adduser: command not found

useradd: Warning: home directory `/home/--help' doesn't exist, and -m was not specified

useradd: pw_mkdb failed: No such file or directory
root@tnt:~# userdel --help
userdel: No such user `--help'
root@tnt:~# man useradd
root@tnt:~# useradd -m -s /usr/pkg/bin/bash friend
useradd: can't obtain pw_lock: File exists
vipw: the passwd file is busy.
root@tnt:~# echo sigh
Don't pass variables to programs without first checking if they will be
seen as flags. Also do more exit code checking, though maybe --help
exits with 0.
