Problem

Simple and easy method for generating random passwords from the command line.

Solution

Use the command below:

LC_ALL=C </dev/urandom tr -cd '[:alnum:]' | head -c 32

Explanation

This command generates a random string, remove non-alphanumeric characters and print the first 32 characters.

Adjust the length of the password by changing the number after -c in head -c 32.

Add symbols by replacing the character class with [:graph:] as in tr -cd '[:graph:]'.
