NAME
       rmdir, rm  - remove (unlink) directories or files

SYNOPSIS
       rmdir dir ...

       rm [ -f ] [ -r ] [ -i ] [ - ] file ...

DESCRIPTION
       Rmdir removes entries for the named directories, which must be empty.

       Rm removes the entries for one or more files from a directory.  If an entry was the last link to the file, the
       file is destroyed.  Removal of a file requires write permission in its directory, but neither read  nor	write
       permission on the file itself.

       If a file has no write permission and the standard input is a terminal, its permissions are printed and a line
       is read from the standard input.  If that line begins with  `y'	the  file  is  deleted,  otherwise  the  file
       remains.  No questions are asked and no errors are reported when the -f (force) option is given.

       If  a  designated  file	is  a directory, an error comment is printed unless the optional argument -r has been
       used.  In that case, rm recursively deletes the entire contents of the specified directory, and the  directory
       itself.

       If  the	-i  (interactive) option is in effect, rm asks whether to delete each file, and, under -r, whether to
       examine each directory.

       The null option - indicates that all the arguments following it are to be treated as file names.  This  allows
       the specification of file names starting with a minus.
