comment Is there a way to check a users SSH key to see if the passphrase is blank
This does not work with the new-style private key format used by OpenSSH 6.5 and later. Most keys you run across will be old-style since even with 6.5 that's the default format, but if you run across a key file beginning with -----BEGIN OPENSSH PRIVATE KEY----- you'll have to dig deeper to tell if it's encrypted.

comment An alias for a command to kill stopped jobs
If you really want stopped jobs, you want jobs -p -s. The -s flag is a bash extension and won't necessarily work in other shells.

Note that these words should be randomly selected. Don't choose them yourself; use dice or a computer. Humans are bad at randomness.
