What is the 'rm -r' command?

The rm -r command is used in Linux to remove directories and their contents recursively. Here's a breakdown of the command:

• rm: This is the command used to remove files and directories.
• -r: This option stands for "recursive," which means that the command will delete not only the specified directory but also all of its contents, including subdirectories and files within them.

For example, to remove a directory named mydirectory and everything inside it, you would use:

rm -r mydirectory

Caution: This command is powerful and irreversible, so be sure you want to delete the specified directory and its contents before executing it.
