Which command allows you to change to the home directory?

The command that allows you to change to the home directory is represented by the tilde symbol, which stands for the current user's home directory. When you execute the command cd ~, the shell interprets the tilde as a reference to the home directory associated with the user currently logged in. This is a convenient way to quickly navigate to the home directory from anywhere in the filesystem.

For context, the other options do not achieve the same result. Using cd / changes the working directory to the root of the filesystem. The command cd .. moves you up one level in the directory tree, navigating to the parent directory of your current location. On the other hand, cd . refers to the current directory, leaving you in the same location without making any changes.

Understanding cd ~ is quite useful as it allows you to quickly return to your home directory regardless of your current path in the filesystem.
