NAME

generate-random-password

SYNOPSIS

generate-random-password [ --length=N ] [ --pattern=string ]

generate-random-password [ --man | --help ]

DESCRIPTION

This program uses perl's internal rand() function to generate random passwords.

OPTIONS

--length=N

Produce a random password with at least this number of characters. The default is eight (8).

--pattern=string

The characters in the pattern string have the following meanings.

p printable

v vowels

c consonants

l letters

n numbers

s symbols

For each upper case character, an element from the set will be used. For lower case characters, an element is used half of the time.

Where necessary, the password is padded out using the last set selected. See the EXAMPLES for more information.

The default is "CVCNCVCN", which matches the default length.

--man

Print the manual page and exit.

--help

Print a brief help message and exit.
