NAME
  mv - move files

SYNOPSIS
  mv [-f] [-i] [source_file] [target_file] [target_dir]

DESCRIPTION
  The mv utility shall move the file named by the source_file operand to the
  destination specified by the target_file. This first synopsis form is assumed
  when the final operand does not name an existing directory and is not a
  symbolic link referring to an existing directory. In this case, if source_file
  names a non-directory file and target_file ends with a trailing <slash>
  character, mv shall treat this as an error and no source_file operands will be
  processed.

OPERANDS
  source_file  A pathname of a file or directory to be moved.
  target_file  A new pathname for the file or directory being moved.
  target_dir   A pathname of an existing directory into which to move the input
               files.

OPTIONS
  -f  Do not prompt for confirmation if the destination path exists. Any
      previous occurrence of the -i option is ignored.
  -i  Prompt for confirmation if the destination path exists. Any previous
      occurrence of the -f option is ignored.
