Which symbol is often used to denote a home directory in command line prompts?

The symbol that represents the home directory in command line prompts is the tilde (~). In Unix-like operating systems, the home directory is the default directory for a user where personal files and configurations are stored. When you use the tilde symbol, it acts as a shortcut to quickly navigate to your home directory without needing to type the full path. This is particularly useful for simplifying commands and scripts.

Although the root directory is denoted by a forward slash (/), and "Home" can describe the home directory in some contexts, neither serves as the shorthand that the tilde does. The option "src" commonly refers to a source directory in programming and software projects but does not have any relation to the home directory in command line usage. Hence, the tilde stands out as the correct choice for indicating the user's home directory in command line environments.
