Simple Shell Random Password Generator

Need a Random Password Quick? Look No Further

Here’s a simple Bash one-liner:

[ "$(uname)" = "Darwin" ] && export LC_CTYPE=C || export LC_ALL=C; cat /dev/urandom | tr -dc 'a-zA-Z0-9!@#$%^&*()_+?><~\`;' | fold -w 32 | head -n 1

Function for Reusability

For situations where you need to generate multiple random passwords, or if you want to reuse the password generation logic in other scripts, you can use a function:

#!/bin/bash

# Function to generate a 32 character random password
randomPass() {

 #Set local variable for password
 local randompass=$(cat /dev/urandom | env LC_CTYPE=C tr -dc 'a-zA-Z0-9!@#$%^&*()_+?><~\`;' | fold -w 32 | head -n 1)

 echo $randompass
}
