How is the tilde used?

The tilde ~ is used in various contexts to represent the home directory of the current user. Here are a few examples:

1. Navigating to the Home Directory:

   cd ~
   

2. Referencing Files in the Home Directory:

   ls ~/Documents
   

3. Using with Commands:

   cp ~/file.txt /path/to/destination/
   

In these examples, ~ expands to the full path of the user's home directory, making it easier to reference files and directories without needing to type the full path.
