Terminal commands are useful ways to navigate between folders, also called directories, quickly and easily. The commands are entered into the terminal or bash.

Open your terminal and do the following:

• * 🔑 We use `ls` to list the contents of the current directory. In the home directory, we see a list of directories including the `Desktop` directory. ```bash ls ```
• * 🔑 We use `cd` to change directories. We can change into the `Desktop` directory with the following command: ```bash cd Desktop ```
• * 🔑 To move back up to our previous directory, we use `cd ..`. ```bash cd .. ```
• * 🔑 We check our working directory with `pwd`. When we print the working directory, it shows us the path. ```bash pwd ```
• * 🔑 To create a new folder inside the `Desktop` directory, we navigate into the `Desktop` directory using `cd`. ``` cd Desktop ```
• * 🔑 We use the `mkdir` command to create a new directory named `demo-folder`. ```bash mkdir demo-folder ```
• * 🔑 To add a file to our new directory, we first use `cd` to navigate into `demo-folder`. ```bash cd demo-folder ```
• * 🔑 We use `touch` to create a new file named `index.html`. ```bash touch index.html ```
• * 🔑 We use `ls` to check that our new file has been successfully added to the directory. ```bash ls ```
