Lab | Bash

Introduction

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

Setup

1. Fork the repo in your git hub account and then clone the folder "lab-bash" to your machine and navigate to it folder.

2. Check the contents of the folder using the "ls" command

$ ls

and you should see the following:

exercises  inputs  lorem  lorem-copy  modules  outputs  README.md

(base) jbadenes-macbookpro:lab-bash-master jbadenes$ ls
exercices	inputs		lorem		lorem-copy	outputs		readme.md```

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

Exercises

1. Using the echo command print in console "Hello World". Here is some info about echo command [https://discuss.codecademy.com/t/what-are-practical-uses-of-the-echo-command/394788]

Hello World```

2. Create a new directory called new_dir.

(base) jbadenes-macbookpro:lab-bash-master jbadenes$ mkdir new_dir

3. Delete/Remove the directory `new_dir`.

```(base) jbadenes-macbookpro:lab-bash-master jbadenes$ rm -r new_dir```

4. Copy the file sed.txt from the lorem folder and paste it to the folder lorem-copy folder.

(base) jbadenes-macbookpro:lab-bash-master jbadenes$ cp -r lorem/sed.txt lorem-copy

4. Copy the file `sed.txt` from the `lorem` folder and paste it to the folder `lorem-copy` folder.
5. Copy the other two files from the `lorem folder` to `lorem-copy` folder in just one line using semicolon `;`.
6. Show the `sed.txt` file content from the `lorem` folder.
7. Show the `at.txt` file and `lorem.txt` file contents from `lorem` folder.
8. Print the first 3 rows in `sed.txt` file from lorem-copy folder.
9. Print the last 3 rows in `sed.txt` file from lorem-copy folder.
10. Add `Homo homini lupus.` at the end of `sed.txt` file in the `lorem-copy` folder.
11. Print the last 3 rows in `sed.txt` file from `lorem-copy` folder. You should see `Homo homini lupus.`.
12. `sed` command is used to replace the text in a file. Use the `sed` command to replace all occurances of `et` with `ET` in the file `at.txt` file present in the folder `lorem`. You can use the following link to refer to `sed` commands [https://www.linode.com/docs/guides/manipulate-text-from-the-command-line-with-sed/]
Check the contents of the sed.txt file using `cat` command.
13. Find who is the system user. 
14. Find the current path of the directory you are in.
15. List all files with the extension `.txt` in lorem folder.
16. Count the rows in `sed.txt` file from lorem folder. Look concatenate `cat` and `wc` with the pipe `|`.
17. Count the **files** which start with `lorem` in all directories.


## Bonus

20. Store your `name` in a variable with `read` command.
21. Print that variable.
22. Create a new directory named with variable `name`.
23. Remove that directory.
