    NAME

    chpasswd - update passwords in batch mode
     
    

    SYNOPSIS

    chpasswd [options]
     

    DESCRIPTION

    chpasswd

    reads a list of user name and 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

    By default the supplied password must be in clear-text. Default encryption algorithm is DES. Also the password age will be updated, if present.

    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 chpasswd command are:

    -e, --encrypted
    Supplied passwords are in encrypted form.
    -h, --help
    Display help message and exit.
    -m, --md5
    Use MD5 encryption instead DES when the supplied passwords are not encrypted.
     

    CAVEATS

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