In the command line, what does the tilde (~) symbol represent?

The tilde (~) symbol in the command line specifically represents the user's home directory. This is a shorthand notation that makes navigation and file management more efficient in a Unix or Linux environment. The home directory is the default directory for a user, where personal files and settings are usually stored.

Using the tilde allows users to quickly reference their home directory without having to type the full path. For instance, if a user's home directory is /home/username, entering cd ~ in the command line would change the current directory to that specific location. It serves as a convenient and intuitive way to access the user's files and folders, streamlining the workflow for commands that involve file paths within that directory.

This functionality is essential for command-line operations and helps in managing files more effectively.
