NAME
       chgpasswd - update group passwords in batch mode

SYNOPSIS
       chgpasswd [options]

DESCRIPTION
       chgpasswd reads a list of group name and password pairs from standard
       input and uses this information to update a set of existing groups.
       Each line is of the format:


       group_name:password

       By default the supplied password must be in clear-text. Default
       encryption algorithm is DES.

       This command is intended to be used in a large system environment where
       many accounts are created at a single time.

OPTIONS
       The options which apply to the chgpasswd command are:

       -e, --encrypted
	  Supplied passwords are in encrypted form.

       -h, --help
	  Display help message and exit.

       -m, --md5
	  Use MD5 encryption instead of DES when the supplied passwords are
	  not encrypted.

CAVEATS
       Remember to set permissions or umask to prevent readability of
       unencrypted files by other users.
