NAME
       mkpasswd - generate new password, optionally apply it to a user


SYNOPSIS
       mkpasswd [ args ] [ user ]


INTRODUCTION
       mkpasswd  generates  passwords  and can apply them automatically to users.  mkpasswd is based on the code
       from Chapter 23 of the O'Reilly book "Exploring Expect".


USAGE
       With no arguments, mkpasswd returns a new password.

            mkpasswd

       With a user name, mkpasswd assigns a new password to the user.

            mkpasswd don

       The passwords are randomly generated according to the flags below.


FLAGS
       The -l flag defines the length of the password.  The default is 9.  The following example  creates  a  20
       character password.

            mkpasswd -l 20

       The  -d  flag  defines the minimum number of digits that must be in the password.  The default is 2.  The
       following example creates a password with at least 3 digits.

            mkpasswd -d 3

       The -c flag defines the minimum number of lowercase alphabetic characters that must be in  the  password.
       The default is 2.

       The  -C  flag defines the minimum number of uppercase alphabetic characters that must be in the password.
       The default is 2.

       The -s flag defines the minimum number of special characters that must be in the password.   The  default
       is 1.

       The -p flag names a program to set the password.  By default, /etc/yppasswd is used if present, otherwise
       /bin/passwd is used.

       The -2 flag causes characters to be chosen so that they alternate between right and left  hands  (qwerty-
       style), making it harder for anyone watching passwords being entered.  This can also make it easier for a
       password-guessing program.

       The -v flag causes the password-setting interaction to be visible.  By default, it is suppressed.


EXAMPLE
       The following example creates a 15-character password that contains at least 3  digits  and  5  uppercase
       characters.

            mkpasswd -l 15 -d 3 -C 5
