comment Why won't the Linux wall command broadcast a string argument?
@mjb It's actually unlikely that the herestring is more efficient than echo - herestrings work by making a temporary file, and then attaching that as a process's stdin (file descriptor 0), which is why wall accepts it (wall reads from stdin if you don't specify a file). As a way of verifying that herestrings create a file, $ readlink /proc/self/fd/0 <<< test will print something like /tmp/sh-thd-4228536315 (deleted).

comment How to manage GPG keys across multiple systems?
In fact, it may be advisable to have another mechanism for revoking keys, using a strong public password that is manually updated (replaced) on a regular basis- this way, you can revoke the key without depending on any device (say you're out with only your phone and somebody steals it), so long as you keep the password a secret.

comment How to manage GPG keys across multiple systems?
The revoking section is a little cloudy as written - revoking a device should be possible with an announcement from any other device (so as to not fail if someone steals your laptop and your phone can't contact the server directly), but not possible to be done by a thief (so devices should have a password-protected key for revocation). In the event of conflicting reports, all keys should be temporarily mistrusted until manual verification by a third party can be performed.

comment How to clear the contents of a file from the command line?
It would be better to use a dedicated null-output command like true (or its builtin alias :), although ultimately you don't need a command at all (see the accepted answer).

comment How does a computer restart itself?
For USB devices triggering a boot, some BIOSes have an option to wake the computer on a double-click or keypress. Also, some Mac keyboards have Power buttons (a tradition going all the way back to the original).
