NAME
chpasswd - update password file in batch
SYNOPSIS
chpasswd
DESCRIPTION
chpasswd reads a file of user name and cleartext password pairs
from standard input and uses this information
to update a group of existing users.
Each line is of the format
user_name:password
The named user must exist.
The supplied password will be encrypted and the password age updated,
if present.
This command is intended to be used in a large system environment where
many accounts are created at a single time.
CAVEATS
The mkpasswd command must be executed afterwards to update the
DBM password files.
The input file must be protected since it contains unencrypted passwords.
This command may be discarded in favor of the newusers(8) command.
