Mnemonic password generator
Should be cryptographically secure, uses /dev/urandom as a source of entropy (and so does sort -R as well as shuf, by default). I'm not sure if entropy estimation is 100% correct. As a rule of thumb, I'd want at least 64 bits of entropy for most things, and at least 128 if you're paranoid or securing something that can be brute forced very efficiently. Needs a dictionary wordlist to be installed, I think most distros come with one? Not sure about mac.
Example output:
$ mnemonic.sh 5
Estimated entropy: 75 bits (37538 candidate words)

$ mnemonic.sh 15
Estimated entropy: 227 bits (37538 candidate words)
