chpasswd - update password file in batch
chpasswd [-e]
chpasswd reads a file of user name and password pairs from standard input and uses this information to update a group of existing users. Without the -e switch, the passwords are expected to be cleartext. With the -e switch, the passwords are expected to be in encrypted form. Each line is of the format
user_name:password |
The named user must exist. The supplied password will be encrypted as necessary, 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.
The input file must be protected if it contains unencrypted passwords.
