What is the purpose of the -r option in the rm command?

The -r option in the rm command stands for "recursive." Its primary purpose is to allow the removal of directories and their contents, including all files and subdirectories within those directories.

Key Points about the -r Option:

1. Remove Directories: Without the -r option, the rm command cannot delete directories. Using -r enables you to delete entire directories.

2. Recursive Deletion: When you use rm -r, it will delete the specified directory and all of its contents recursively. This means that all files and subdirectories within the specified directory will also be deleted.

3. Usage:

   • To remove a directory named example_directory and all its contents, you would use:

     rm -r example_directory

4. Caution: Using rm -r can be dangerous, especially when combined with the -f (force) option, as it will permanently delete everything without prompting for confirmation. Always double-check the command and ensure you are targeting the correct directory to avoid accidental data loss.

Example:

rm -r /path/to/directory

This command will delete the specified directory and everything inside it.
