What is the command to delete files in linux

In the Linux environment, the command to delete files is rm. Use this command to free up disk space by removing files that are no longer needed from the file system.

-r, -R: recursively delete directories and their Content;
-f: Forced deletion, no confirmation required;
-i: Interactive deletion, ask for confirmation before deletion;
-v: Display the name of each deleted file.
