It helps you save a ton of time while navigating in the filesystem. Let’s put this into action and see how cool this command can be. If your working directory is deeply nested inside the filesystem and you need to return to your home directory, this is where the ~ comes in with the cd command. Then, you can move to the filesystem’s root ( /) by issuing this command: $ cd / You can verify this by issuing pwd command. The other way is to provide the absolute path to the directory: $ cd /homeĮither way, we are now inside /home. represents the directory one level above the working directory. One way is to issue a cd command relative to your pwd: $ cd. If you need to move one level up from your working directory, in this case /home, we can do this couple of ways. In your case, it is probably /home/.Ībsolute and relative paths make more sense when we look at examples for the cd command. When you log into a Linux machine or fire up a terminal emulator, by default your working directory is your home directory. The cd command lets you change to a different directory. If you are in your home directory, for example, the ls command's relative path is. The relative path is relative to your present working directory. If it’s not absolute, then it’s a relative path. For example, the absolute path to the ls command is: /usr/bin/ls. Note that it is a best practice to use absolute paths when you use file paths inside of scripts. It is relative to the root directory ( /). What is an absolute path? An absolute path is the full path to a file or directory. This command comes to your rescue when you get lost in the filesystem, and always prints out the absolute path. The pwd command prints the current/working directory, telling where you are currently located in the filesystem. This navigation command overview will help you to better understand how all of this works. I believe that the best way to understand any concept is by putting it into practice.

The tilde ( ~) represents the home directory of the currently logged in user.

(Every directory/file in the Linux filesystem is nested under the root / directory.)

The forward slash ( /) represents the 'root' of the filesystem.

) represents one level above the current directory.

) represents the current directory in the filesystem. ), forward slash ( /), and tilde ( ~), all have special functionality in the Linux filesystem:
