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 permis-

sion 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. ...
