     rm  - remove (unlink) files

     rm [ -f ] [ -r ] name ...

     Rm removes the entries for one or more files from a direc-
     tory.  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, rm prints the file name
     and its mode, then reads a line from the standard input.  If
     the line begins with y, the file is removed, otherwise it is
     not.  The question is not asked if option -f was given or if
     the standard input is not a typewriter.

     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.  To remove directories per se see

     /etc/glob to implement the -r flag

     rmdir (I)

     When rm removes the contents of a directory under the -r
     flag, full pathnames are not printed in diagnostics.
