# mkpasswd.pl(1p)

example to generate new password with String::MkPasswd

## NAME

mkpasswd.pl - example to generate new password with String::MkPasswd

## SYNOPSIS

```
  mkpasswd.pl [-options]
  #!/bin/sh
  NEW_PASSWD=`mkpasswd.pl`
```

## DESCRIPTION

This program generates a random password, allowing for some tuning of character distribution.  The password is sent to standard output.

### OPTIONS

- \-l # \| --length=#

  The total length of the password.  The default is 9.

- \-d # \| --digits=#

  The minimum number of digits that will appear in the final password. The default is 2.

- \-c # \| --lower=#

  The minimum number of lower-case characters that will appear in the final password.  The default is 2.

- \-C # \| --upper=#

  The minimum number of upper-case characters that will appear in the final password.  The default is 2.

- \-s # \| --special=#

  The minimum number of non-alphanumeric characters that will appear in the final password.  The default is 1.

- \-2 \| --distribute

  If specified, password characters will be distributed between the left- and right-hand sides of the keyboard.  This makes it more difficult for an onlooker to see the password as it is typed.

- \--nodigits \| --no-digits

  Alias for --digits=0.

- \--nolower \| --no-lower

  Alias for --lower=0.

- \--noupper \| --no-upper

  Alias for --upper=0.

- \--nospecial \| --no-special

  Alias for --special=0.

## BUGS

- •

  While not really a bug, the .pl extension has been added to avoid conflict with the program of the same name distributed with Expect.

## TODO

- •

  For completeness, add user password setting functionality as found in Expect's [**mkpasswd**(1)](/mkpasswd/1.md) example.
