The actual shell tricks are mostly as old as bash itself mostly... except the
<<< which strikes me as unneeded.

crontab - <<< '*/15 * * * * top -n 1 -b'

echo '*/15 * * * * top -n 1 -b' | crontab -
crontab - < echo `'*/15 * * * * top -n 1 -b'`

That "top" trick is silly since ps does it easier without
requiring you to much
around with the default top settings.

ps O rss | sort -n +2

ssh-copy-id isn't an OpenSSH command iirc... I definately don't have it here on
my OpenBSD box which I suspect has all the OpenSSH tools.

However, only #1, #2 and #4 are actually shell tricks.  A shell trick isn't
some spiffy use for a command, it's a trick that the shell does.

For example, to create an empty file... rather than use "touch empty" use
":>empty" which works in every shell I've used, not just bash.

THAT'S a shell trick.  :-)
