What does the rm-rf command in Linux refer to?

In Linux, "rm -rf" is a dangerous and powerful command used to delete files and directories. Among them, "rm" is the delete command, and "-rf" is the combination of the two options.

  1. The "-r" option indicates recursive deletion, that is, deleting all files and subdirectories in the specified directory. If you do not use the "-r" option, when the specified directory is a non-empty directory, it will not be deleted.

  2. The "-f" option indicates forced deletion, that is, files and directories will be deleted directly without any prompts. If you do not use the "-f" option, when deleting some special files or directories, a prompt message will appear asking you to confirm whether to delete it.

Therefore, the "rm -rf" command will recursively delete all files and subdirectories in the specified directory without any prompt message. This command needs to be used with caution because once executed, deleted files and directories cannot be recovered.
