What Does Rm Command Do?

The Rm Command is a basic command used to delete files and directories. It passes its command as-is to the operating system. Unlike other commands, this one does not perform error checking.

rm removes symbolic links. It does not delete the actual file or directory, but only the references. It is important to note that this command does not erase data; it just removes the reference. Despite the name, the data may still be on the file system. However, the hardened versions wipe the data on disk when the last link is cut. To prevent accidental file deletion, rm is commonly wrapped around a -i option.
