How do you generate random strings with basic Unix tools?
Of course every language has some kind of `random` library... But can you generate custom random strings with just basic CLI tools?

For example, we have `/dev/random` which provides a stream of random values... But they're random bytes, so a lot of them are non-printable or special characters. If I want a random number of random alphanumeric string, how do I get that from `/dev/random`?
