Delete one or more
files. To remove a file, you must have write
permission in the directory that contains the file, but you need not
have permission on the file itself. If you do not have write
permission on the file, you will be prompted (y or n) to override.
Prompt for y (remove the file) or n (do not remove the file).
Mark the end of options (rm still accepts -, the old form). Use this when you need to supply a filename beginning with -.
