It seems to me learning how to use the terminal is a prerequisite to learning how to use Ubuntu. So I'm trying to figure out the best way to learn. Is there a Quizlet online flash card set out there? A better way?

If you want a crash course, "How to Get a GUI Back After I Accidentally Fubared the Config Files So Badly Only the Shell Will Load" is always a winner. Be warned that if you lose the game possible penalties include buying a greybearded friend a case of his beverage of choice or reinstalling the OS. –  Dan Neely Aug 26 '13 at 15:38

@fluffy: That's not even hard: rm -- '-rf ~/*'. For a real challenge, try deleting a file whose name consists entirely of unprintable control characters. Bonus points if just printing the name messes up your terminal. –  Ilmari Karonen Aug 27 '13 at 0:28

That's not too hard either :P rm -i * and just answer yes when you come across the right file. –  ovc Aug 27 '13 at 8:36

Does "real life" count as a game? –  Jonathan Aug 27 '13 at 10:58

You can add the following line (command) at the end of your ~/.bashrc file:

echo "Did you know that:"; whatis $(ls /bin | shuf -n 1)

Every time you open the terminal you will learn something about a random command.


If you want some fun, you can use cowsay "utility". To install it, run this in terminal:

sudo apt-get install cowsay

Then add the following line at the end of your ~/.bashrc file:

cowsay -f $(ls /usr/share/cowsay/cows | shuf -n 1 | cut -d. -f1) $(whatis $(ls /bin) 2>/dev/null | shuf -n 1)

Or you can add the above line as alias in ~/.bash_aliases. I added:

alias ?='cowsay -f $(ls /usr/share/cowsay/cows | shuf -n 1 | cut -d. -f1) $(whatis $(ls /bin) 2>/dev/null | shuf -n 1)'

Whenever you get bored, you can type in terminal: ? (followed by Enter). It's like playing dice by yourself.

That's extremely cool, but on my distro (Ubuntu 13.04) using the default shell I get Did you know that: mkdir: nothing appropriate. every time I start a shell (to be pedantically clear, I don't always see mkdir but I do always see nothing appropriate). whatis works if I put your line of code at the top of ~/.bashrc but not at the end. Not sure what it is that messes it up, but I guess others will run into the same problem. –  snim2 Aug 26 '13 at 18:17

@user606723 I chose only /bin because over there are the most used commands. But you can use echo "Did you know that:"; whatis $(ls /usr/share/man/man1 | shuf -n 1 | cut -d. -f1) to choose a random page from all man pages. –  Radu Rădeanu Aug 26 '13 at 20:01

@RaduRădeanu do not parse the output of ls! –  heinrich5991 Aug 26 '13 at 20:05

@heinrich5991 of course you are correct in general, but if anything in your /bin has spaces or newlines in its name then you have bigger problems than bad scripting habits... –  evilsoup Aug 26 '13 at 21:40

@snim2 I suspect the problem is be an alias for ls that adds -F or some other flag that affects the output. Change ls /bin to /bin/ls /bin. –  Gilles Aug 27 '13 at 14:40

I used to play with whatis. It's not exactly a game, but it's a relatively easy way to learn.

For example, type whatis sudo apt-get update and it returns:

enter image description here

Before I execute any command, I hit it with whatis first. I learn what I'm going to do, then I will do the command with confidence.

If whatis doesn't provide much information or if it's unclear to me, I will go to and read the man.

For example, man sudo.

Google gives you so much info here, sources inside Ask Ubuntu and outside. Here, LMGTFY: best way to learn terminal commands on Ubuntu

I'd highly recommend to follow whatis something with a thourough read of man something BEFORE using the "something" command ^^ . Especially for some (most!) commands, ie dd for example... Man would, for example, also explain the "update" parameter in the example you provide yourself... In your example, whatis shows what is "apt-get" and then tries to find definition of "update" command, which doesn't exist (but could have and be something completely irrelevant) –  Olivier Dulac Aug 26 '13 at 12:50

Yes, Terminus is once such game that will help. There is a live version here, and the code is on github. It's a neat idea, although I rather wish the code was more easily extensible.

I do not know of any games, however there are some useful command line utilities that help.

What does a command do?

whatis command
# example:
$ whatis cut
cut (1)              - remove sections from each line of files

How do I?

man -k keyword
# example:
$ man -k "remove empty"
rmdir (1)            - remove empty directories

Alternatively:

apropos keyword  
# defaults to printing every result with at least one of the keywords supplied
#   use --and to only print results matching multiple keywords.
$ apropos zip --and extract
funzip (1)           - filter for extracting from a ZIP archive in a pipe
unzip (1)            - list, test and extract compressed files in a ZIP archive
unzipsfx (1)         - self-extracting stub for prepending to ZIP archives
uz (1)               - gunzips and extracts a gzip'd tar'd archive

How do I use?

man command
# example:
man tar
# use '?' key to search, and 'q' to quit.

Or, some utilities support a help option, such as:

$ umount --help
Usage: umount -h | -V
   umount -a [-d] [-f] [-r] [-n] [-v] [-t vfstypes] [-O opts]
   umount [-d] [-f] [-r] [-n] [-v] special | node...

These may be in the form of command -h, command --help, command -?.

For information:

info command
# example:
$ info cat
# shows an information page

If you have something specific you need to accomplish, Google is your friend. Otherwise there are many books, such as the Bash book from O'Rielly.

i'd avoid using < and > at all, as persons who need direction to use man may not know the danger of redirection . For example : command <something> somethingelse will create a somethingelse empty file (or truncate an existing one!) in the current dir. It's a bad habit. Just using man command is quite self explanatory. Or man __some__command__ or anything safe. –  Olivier Dulac Aug 26 '13 at 13:02
    
hmm, actually it's safe if the <something is not an existing file, as otherwise the shell will complain it doesn't exist (apparently does so BEFORE creating the output file)... But still, bad habit –  Olivier Dulac Aug 26 '13 at 13:03

Good point. Just used to writing documentation in that format. (edit) Removed them. –  Der Flatulator Aug 26 '13 at 15:38

Take a look at command line fu

You can browse some cool command line snippets, and if you want deeper understanding you can read the manuals of the commands they use.

Ubuntu was designed to be very user friendly. Learning how to use the terminal is not a prerequisite to learning how to use Ubuntu. It is, however, if you want to become a power user or troubleshoot problems yourself.

To answer your question, I don't know of any games designed to help or teach shell commands, but I would highly recommend the following resources bash and system administration related:

You've got tons of games on http://overthewire.org. The easiest is Bandit, "aimed for absolute beginners".

Excellent link. Seems like there are many wargames in there. Bandit seems to be the game for absolute beginners like me. –  Sundeep Nov 20 '13 at 12:20

There is a game for learning the VIM commands at http://vim-adventures.com/ which I recommend. I get my apprentices to play it on their first day :-)

The Memrise Tool has a unix and linux command line section. It's a great tool for learning anything in a punch card manner.

There's also the ShellFu course. While Memrise is not a game per se, I still find it very engaging and it does play on your competitive nature. –  ThomasH Aug 31 '13 at 18:50

There is the game Uplink. It's been quite fun and threre are pretty good similarities to a linux shell. But it's got its own commands as well.

While Uplink is a great game, it's command line is limited to cd, dir, delete and reboot. Quite insufficient. I remember there's another hacker game where you actually have to write shell scripts, but I forgot the name. Probably something creative as "hackers" –  Tobias Kienzler Aug 27 '13 at 14:04

The best tool I have found for long term memorization and learning is Anki

http://www.ankisrs.net/

I use create cards in Anki that require me to type the answer, rather than simply a flash card. It builds the muscle memory. Additionally I perform 15 minutes of training every morning and Anki will sort my cards based on the ones I need to review.

share|improve this answer
    
Sounds like a good tool, but does it also provide the training data for terminal commands? –  gertvdijk Aug 27 '13 at 14:11

In the early UNIX days (v6 and v7) (yes before Linux), there was a series of very simplistic tutorials under the command called learn. I must admit, I started my training there .. it had tutorials on command line, vi, and a little bit of C programming. It has long since disappeared. And of course, this was before the proliferation of books on this subject, the high amount of easy internet connectivity, basically all you had was basically the man pages.

So now it is quite easy, basically go to Google, either find some documentation posted. Or use amazon to find an appropriate book. Amazon even has ratings and reviews on their books.

Well, most of the basics I learned when Linux was still mostly command-line based and SUSE was one of the few Linux with GUI-based installation. I played around with Gentoo these times...just install your system with some tools like pm-sensors and stuff, soon you're back in the terminal for some configuration

I don't know if there is still a distro that is installed via command-line, as I stopped working with Linux till a month ago, when I found out they finally made the step to getting GUI-based and interesting for Users, great thanks to all programmers out there, that made a lot of my old PCs useful again!!!

Stupid MS simply IS too stupid for maintaining their best product any longer...Windows XP...a company that does that, surely is not considering to get an OS fully stable and safe...and in case of Win 7 they may got it very stable and secure, but it takes way to much resources to do so.

Really love the Linux way off controlling hardware without huge compilers or interpreters or other stuff in the way, like on Windows.

But if you want learn more about Linux, Gentoo is a great way of building up your own system, step by step and also learn how Linux works. Gentoo also is able to run on nearly everything, no matter how small the hardware resources, so you can take a other, older PC for these Linux, install-test, fun times!

Not exactly a game, but there is this site, where you can learn several different commands.

Not a game but take a look at http://www.stanford.edu/class/cs124/kwc-unix-for-poets.pdf

It covers sed, awk and grep besides others and shows you how to count, sort, compute ngrams etc. It has exercises and all. I've referred to it again and again.

The matrix for game cube is where I learned quite(relative to my 13 year old prior knowledge) a bit about the UNIX terminal. There was a mini-game where you'd "hack" your way into the matrix to drop guns off for pickup later when you are playing that level. Actually bar far one of my favorite features of any game ever.
