Generate password and print to stdout?

[Alexandre Pujol]

Hi all,

I use a simple bash function that generates password using /dev/urandom,
and tr the exact same way pass does it.

Then I have a few aliases to easily generate password/pin...

As example:
_pw() {
	local characters="${1}" length="${2:-25}"
	bash -c 'read -r -n "$0" pass < <(LC_ALL=C tr -dc "$1" < /dev/urandom)
&& echo $pass' $length $characters
}

alias pw='_pw "[:graph:]"'
alias pw2='_pw "[:alnum:]"'
alias pin='_pw "[:digit:]"'

This is actually not a good things because you are generating only
base64 password.
