Note from last time and routing:
	My IP address had already updated
	But the computer I send connections to was off!
		Good IT question:  "Are you certain it is turned on?"

grep to search files
	A few special characters:
		^ and &
		. (period)
		* (0 or more of previous)

Can we cheat at wordle?
	/usr/share/dict/

Pipes
	One command can process the output of another!
	We need something longer for this
	cpuinfo, how fast are our CPUs running?
	When did people try to guess the root password?
	What passwords were missed that weren't for root?
	Make up a few more

A few more commands that can be helpful:
	head
	tail
	sed

Since we know C++:
	Let's make a stream tool that does something!
	Maybe remove all caps?
