Subject: Re: RFC - Linux Command Cheatsheet

Just a few errata and suggestions:
dpkg -[r,P] argument is package-name, not pkg.deb (you specify the package name, not the deb file for those operations)
apt-get upgrade will only update packages that do not require any other package to install/uninstall.  apt-get dist-upgrade upgrades all packages.
apt-get purge package-name will purge a package without the clumsy --purge syntax.
I would change the su - to sudo su -, since most distros no longer have the root password enabled, and you don't want to encourage your students to do that.
I would drop su -c command, sudo serves that purpose.  Add sudo -u username command to run a command as a specific user in it's place.
I'm not sure if you can squeeze it in, but lsattr will list extended attributes, which is helpful when you encounter things like files even root cannot modify.  The corresponding chattr changes extended attributes, of course, but that may not be a good command to mention due to it's higher risk.
I would put kill and killall in red, especially since killall will do partial match (try "sudo killall -9 in" for some system-killing fun sometime) and actually matches on regex.
It might be a very good idea to add "-i" to killall, so the new user has a slightly higher margin of safety for a mistyped command name.
for "program &" you might want to put "program" in italics to make it clear it's not a literal command.
The 6 tar lines seem a little overkill.  Perhaps it would work better with fewer repeated lines coupled with a recommendation to check the manual for the complex commands (like tar, rsync, ip, grep, etc...) that have several common use patterns and really need more room than you have.

You might also save some space by removing reboot and halt (which are actually the same program, much like egrep/fgrep/grep) in favor of shutdown [-r, -h] (which is generally preferred anyway)
