Which symbol is used to represent the home directory in Linux?

The symbol representing the home directory in Linux is the tilde (~). This character is commonly used in command-line interfaces to quickly reference the user's home directory without needing to type the full path. For example, if a user's home directory is /home/username, simply using ~/ will effectively point to that directory, allowing for simpler navigation and file manipulation.

In practical usage, when commands are issued in a terminal, one can use the tilde to navigate to the home directory directly or to specify paths relative to the home directory, making it an efficient shorthand. This is particularly useful when dealing with multiple users, as the tilde always corresponds to the home directory of the currently logged-in user. Thus, it's a universally recognized convention in Unix-like operating systems.
