Lab | Bash

Introduction

In this lab, we are going to practice with bash, a shell and command-line language!

Setup

1. Open a Terminal in your system:

   • Linux/MacOS users: open a terminal in your system.
   • Windows users: open GitBash in your system

2. Download and install the Sublime text editor for your OS here.

3. Open the Sublime text editor side by side with the Terminal.

4. Fork this repo in your git hub account and then clone it into the folder Week_1/Day_1/ of your machine. This will create a folder called "lab-bash" inside.

5. Use the terminal to navigate to the "lab-bash" folder.

6. Use the Sublime menu to open a new empty file in the "lab-bash" folder and name it "lab_solutions.txt".

7. Check the contents of the folder using the "ls" command in the Terminal.

ls

and you should see the following:

exercises  inputs  lorem  lorem-copy  modules  outputs  README.md

8. Stay in the same directory/folder and complete the following exercises.

9. To provide your solutions, test your solution in the terminal and once you figured out the solution to each exercise do the following:

• Copy the statement of each exercise on the "lab_solutions.txt" file opened in the Sublime text editor
• Add the Terminal command needed to solve each exercise on the "lab_solutions.txt" just below the exercise statement as shown below:

terminal_command # replace "terminal_command" with the command that you used in the terminal to solve the exercise

• Save the "lab_solutions.txt" file.

10. Once you finished all the exercises type the following in the Terminal:

    • git status
    • git add lab_solutions.txt
    • git commit -m "Lab solutions"
    • git push origin master

11. Copy the url of your forked GitHub repo on the student portal.
