pass

The 'pass' command generates random passwords.

All you have to do is to install the gem

$ gem install pass

You can just run 'pass' to get one random password. Every time you run it, you will get a different password.

Each password has 20 characters and does not include ambiguous characters l o I O 1 " ' ` |. As default, a password consists of upper case letters, lower case letters, and numbers.
