The command "fossil rm --hard ${filename_or_directory}" is used to permanently remove a file or directory from the Fossil version control system repository. Let's break down the command:

• "fossil": It is the command-line interface (CLI) tool for managing a Fossil repository.
• "rm": It stands for "remove" and is used to delete files or directories.
• "--hard": It is an option that ensures the removal is permanent and cannot be undone. Once executed, the file or directory cannot be recovered.
• "${filename_or_directory}": This is a placeholder for the actual name of the file or directory that you want to remove. You need to replace it with the specific name of the file or directory you want to delete.

Therefore, when you execute the command, it removes the specified file or directory completely from the Fossil repository, ensuring it cannot be recovered.
