cd
The ‘cd’ command is used to change the directory that you are currently in. To change from your current directory, to the parent directory we use the special “..” pointer discussed earlier.

In this example, I navigated from “Subdirectory” back to its parent “Tutorial”. If we recall paths from earlier, I could have also specified an absolute path - “cd ~/Tutorial” to achieve the same result. Furthermore, relative paths are also supported by cd.

pwd
The ‘pwd’ commands prints your current working directory.

As we can see, it displays the absolute path of my current directory.
