A day in the life of a unix nerd:
	Spotify, FreeBSD, authentication, widevine, mDNS and zeroconf, etc.

Short list of commands still to come:
	sed
	cut (I've mentioned it)
	stuff related to compression, archives, and encryption
	Better to have a short list you remember!
		Feel free to learn others!
		Like curl (used with turnin)

Network tools:
	wget
	nc (netcat)
	nmap
	traceroute
	There are plenty more, but this is ok for now

fstab
	uuid and devices
	Partitions, extended and primary
	Numbering:  hd*, sd*, nvme

fdisk will show you
	cfdisk = Curses Fdisk

sshfs:  Mount a filesystem over SSH
	Userspace mounting
	fuse
	Connections are NOT automatically re-established
		- Could use a loop...

locate:
	This runs fast, because it consults a database
		- updatedb updates the database

find, although we've actually been using it already:
	This doesn't use a database
	Tests, example:  -type (b|c|d|f|l)
	Another example:  -name
	man has a list
	Logic operators!  -and, -or, -not, ( )
		- Remember, the shell will still expand stuff
	Actions:  -delete, -ls, -print (default), -quit
	Actions can be in logical operators!
		- lazy evaluation and actions
	xargs vs. backticks
		- xargs will do multiple batches
		- xargs can do multiple processors
		- -n option, for separate invocation

Archives!
	tar is a common unix archive
		- "tarballs"
		- tar command manipulates these (-cf to make, -xf to extract)
		- Meaning of -f, standard input
	Unix philosophy:  A toolbox
	Compression!
		- gzip
		- bzip2
		- xz (LZMA, like 7zip without 7zip 		
	You can compress files that aren't archives
		- Example:  zcat and logs
	tar can run the compression program for you!
		- tar -czf, -xzf, some people use -czvf and -xzvf
	
Backups often use tar
	- Example:  annelid (is only kind of backed up)
	- Distributed systems, and distributed backup
	- Two is one, and one is none
		+ When the zombies arrive...

cron again
	- At some point, I should really show you how to use this!
	- System administration:  /etc, cron has stuff in here
	- There's a way to do cron as a regular user, but I forgot how
		+ Why would you want this?

.zip archives:
	- These were popularized with WinZip, but they're not bad
	- zip tool, unzip tool
	- I use these more than .tar.gz
		+ Go with the flow

xargs example:  Download all CS228 assignments in parallel
	- Side note:  Web spider
	wget can already do this

Scripting:
	Scripts can be pretty elaborate!
	Example:  spectre-meltdown-checker.sh
	They can even have a GUI!
	cdrtoaster

If we're here:
	Active learning on archiving!
	Make a .zip file that has a file in it
		Call it al0930.zip
		I don't care what file
