Practice What You Learned

Terminal Practice In Breakout Rooms


Episode X: A New Terminal

A long time ago in a Unix environment far, far away, young Jedi padawans who knew only of desktop software were seduced by the dark side of the Force to enter… The Terminal.

Follow the instructions below using all the console commands introduced in Fundamentals, class, or that you find on your own.




Setup

  • Open the Terminal/HYPER app
  • Inside the git-github-and-terminal folder, create another folder called: galaxy-far-far-away
  • Then create a file inside galaxy-far-far-away called commands.txt
  • Paste the answer to each numbered question (i.e. the command(s) that accomplished the task) in commands.txt once you get it to work
  • Remember, you can learn about any Unix command by typing man and then the command name. E.g., man ls. Type Q to get out of the Manual page ("man page") viewer



Part I: Set the Scene

Complete all work inside the galaxy-far-far-away folder.

  1. Create a directory called death_star, and make the following files inside of it: darth_vader.txt, princess_leia.txt, storm_trooper.txt
  2. In galaxy-far-far-away, make a directory named tatooine and create the following files in it: luke.txt, ben_kenobi.txt
  3. Inside of tatooine make a directory called millenium_falcon, and in it create: han_solo.txt, chewbaca.txt



Part II: mv - rename

You can rename a file using the mv command.

  1. Rename ben_kenobi.txt to obi_wan.txt



Part II: cp - copy

You can copy a file from one location to another using the cp command. (man cp for more info)

  • Directories can be sibling (parrell to each other) or can be parents (the folder that contains the folder you are in)
  • Copy storm_trooper.txt from death_star to tatooine



Part IV: mv - move

You can use the mv command to move files from one location to another. mv can be used for renaming, moving, or both. Run man mv to see the options—remember hit the Q key to get out of the manual page viewer.

  1. Move luke.txt and obi_wan.txt to the millenium_falcon
  2. Move millenium_falcon out of tatooine and into galaxy-far-far-away
  3. Move millenium_falcon into death_star
  4. Move princess_leia.txt into the millenium_falcon



Part V: rm - remove

BE CAREFUL WITH rm!!! THERE IS NO "TRASH" IN THE UNIX CLI. WHEN YOU DELETE SOMETHING IT IS GONE FOREVER!!!

You can use rm to delete a file.

  1. Delete obi_wan.txt.



Part VI: all together

  1. In galaxy-far-far-away, make a directory called yavin_4
  2. Move the millenium_falcon out of the death_star and into yavin_4
  3. Make a directory in yavin_4 called x_wing
  4. Move princess_leia.txt to yavin_4 and luke.txt to x_wing
  5. Move the millenium_falcon and x_wing out of yavin_4 and into galaxy-far-far-away
  6. In death_star, create directories for tie_fighter_1, tie_fighter_2 and tie_fighter_3
  7. Move darth_vader.txt into tie_fighter_1
  8. Make a copy of storm_trooper.txt in both tie_fighter_2 and tie_fighter_3
  9. Move all of the tie_fighters out of the death_star and into galaxy-far-far-away



Part VII: rm -r: remove directories and everything they contain

BE CAREFUL WITH rm -r THERE IS NO TRASH CAN IN THE UNIX CLI. WHEN YOU DELETE SOMETHING IT IS GONE FOREVER

Before you hit enter, make sure are deleting the right thing, or you could accidentally delete the contents of your computer (it has happened).

This command will not typically ask you if you "really want to delete." It will just delete.

  1. Remove tie_fighter_2 and tie_fighter_3



Part VIII:

  1. Touch a file in x_wing called the_force.txt
  2. Destroy the death_star and anyone inside of it
  3. Return x_wing and the millenium_falcon to yavin_4

Celebrate. You've reached the end of this homework :)




Commit and push your updated code:

"Add" your changes (prepare them to be "committed"):

$ git add -A

"Commit" your changes—any time you make a commit, you can always restore the files in the repo to that point:

$ git commit -m "Completed lab"

"Push" your commits to github:

$ git push origin master

Conclusion

You will "git" plenty of practice as we progress through this program, so if the concept of git/github still seems a little fuzzy at this point, rest assured you will soon "git" it once you "git" some more practice in. 😎
