Bash Basics Introduction

Creating directories

In Bash, directories can be created using the mkdir command. Here's how to do it:

mkdir new_directory

This command will create a new directory named 'new_directory' in the current directory.

Navigating directories

To navigate between directories, we use the cd command. The following command will change your current directory to the new_directory:

cd new_directory

You can return to the parent directory by using:

cd ..

And you can go to your home directory just by using cd with no arguments:

cd

Creating Files

Files can be created using the touch command:

touch new_file.txt

This command creates a new empty file `new_file.txt` in the current directory.

Editing and Saving Files

There are several text editors available in Linux that can be used to edit files; nano, vi, and emacs are a few. Here we can use nano, which is intuitive and easy to use.

To edit a file:

nano new_file.txt

This will open the file `new_file.txt` in the `nano` editor. You can then type or paste in the text you want to save. Once you're done editing, you can save and exit the file by pressing Ctrl + X, then Y to confirm that you want to save the changes, and then Enter to confirm the file name.
