NPASSWD(1)

NAME
npasswd - change login password

SYNOPSIS
npasswd [ -P ] [ -V ] [ username ]

DESCRIPTION
Npasswd changes or installs a login password for username (your own by default). Only the super-user can change another users' password.

When changing a password, npasswd prompts for the old password and then for the new one. The new password must be typed twice to forestall mistakes. The new password is checked for reasonableness.

Npasswd accepts the option switches of the 4.3BSD and SunOS 4.X passwd but impliments none of them. The -V option prints version and patch level information.

The -P option indicates that npasswd will be fed input from another program via a pipe. This option is reserved for the super-user.

Npasswd can change both local passwords and passwords in a Network Information Service (aka Yellow Pages) database.

THIS IS NOT A REAL MANUAL PAGE
It will probably be easier to adapt the manual page for the existing version of passwd installed. I have put much of the particulars about configuring npasswd into the help file.

DIAGNOSTICS
Various, hopefully self-explanitory.

BUGS
This program could do shells and fullnames. Probably a future version will. Since it tries to work for a range of UNIX systems, it will without doubt not do everything quite as well as the vendor-supplied version.
