First, another C string example:
	How about calculating the number of vowels?

Another note on nc:
	plaintext vs. encrypted
	nc normally sends in plaintext
	aespipe
	ssh port forwarding

text-based config files:  Another look
	"Where is the setting" usually ends in a text file
	System:  in /etc 
		Example:  /etc/hostname
	User:  Home directory, name probably starts with .
		Example:  .ratpoisonrc (nc example)	
		Example:  .vimrc
	Might be in ~/.config
		Example:  kitty.conf

Commands we haven't really talked about much yet:
	cut
		Can we make a list of IP addresses trying to guess isoptera's password?
		Compared with grep -o
	sed
	file
	sleep
	curl
		turnin, for example
