MKPASSWD(1) General Commands Manual MKPASSWD(1) 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 "Ex- ploring 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 charac- ters that must be in the password. The default is 2. The -C flag defines the minimum number of uppercase alphabetic charac- ters 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/yp- passwd is used if present, otherwise /bin/passwd is used. The -2 flag causes characters to be chosen so that they alternate be- tween 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 SEE ALSO "Exploring Expect: A Tcl-Based Toolkit for Automating Interactive Pro- grams" by Don Libes, O'Reilly and Associates, January 1995.
