Which keyword is used to refer to the absolute path in Linux?

The absolute path in Linux represents the complete directory location starting from the root directory. This path always begins with a forward slash (/) which signifies the root of the file system hierarchy. For example, an absolute path could look like "/home/user/documents", indicating that the path starts from the top-level directory and leads precisely to the desired location without any ambiguity regarding the current working directory.

Other choices represent different concepts within the Linux filesystem:

• The double dot (..) is used to reference the parent directory of the current working directory. This means it allows navigation up one level in the directory structure, but it does not denote an absolute path.

• The tilde (~) is used as a shortcut to refer to the home directory of the currently logged-in user. While it is a form of shorthand for paths, it is not considered an absolute path because it relies on the user's home directory context.

• The dot followed by a slash (./) indicates the current directory and is often used to execute scripts or programs located in that directory. Like the double dot and the tilde, it does not represent an absolute path but is relative to the current directory.

Thus, the forward slash is the only choice that correctly signals the start of an absolute path in
