NAME
       rm, rmdir  - remove (unlink) files

SYNOPSIS
       rm [ -fri ] file ...

       rmdir dir ...

DESCRIPTION
       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 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  recur-
       sively 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.

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

DIAGNOSTICS
       Generally  self-explanatory.   It  is  forbidden to remove the file `..' merely to avoid the antisocial consequences of inadvertently doing
       something like `rm -r .*'.
