rm [options] files

rm

rm [options] files

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. rm is often aliased to rm -i, especially for the root user, to protect against inadvertently deleting files.
Options
-d, --directory

    Remove directories, even if they are not empty. Available only to a privileged user.

-f, --force

    Remove write-protected files without prompting.

--help

    Print a help message and then exit.

-i, --interactive

    Prompt for y (remove the file) or n (do not remove the file).

--no-preserve-root

    Do not treat root (/) specially. This is the default.

--preserve-root

    Do not operate recursively on root (/).

-r, -R, --recursive

    If file is a directory, remove the entire directory and all its contents, including subdirectories. Be forewarned: use of this option can be dangerous.

-v, --verbose

    Verbose mode (print the name of each file before removing it).

--version

    Print version information and then exit.

-- 

    Mark the end of options. Use this when you need to supply a filename beginning with -.

    To remove a file whose name starts with a `-', for example `-foo', use one of these commands (the same as `mv' command):

    rm -- -foo 
    rm ./-foo
