Short for Print Working Directory, the pwd command simply outputs the full path of the currecnt directory you are working in. This is useful when navigating your file system and you need to know the path of a specific file
In the example above, the user is displaying their current directory in two different place. They first use the pwd command and it shows they are in the /home/osboxes directory. Then the user changes to the desktop before using pwd again to show they are in the /home/osboxes/Desktop directory.
