CHPASSWD(8)                                                        CHPASSWD(8)



NAME
       chpasswd - update password file in batch

SYNOPSIS
       chpasswd [-e]

DESCRIPTION
       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.

CAVEATS
       The  input file must be protected if it contains unencrypted passwords.
