mv —
| mv | [ -fhiv] source target | 
| mv | [ -fiv] source ...
      directory | 
mv utility renames the file named
  by the source operand to the destination path named by
  the target operand. This form is assumed when the last
  operand does not name an already existing directory or when the
  -h flag is specified.
In its second form, mv moves each file
    named by a source operand to a destination file in the
    existing directory named by the directory operand. The
    destination path for each operand is the pathname produced by the
    concatenation of the last operand, a slash, and the final pathname component
    of the named file.
The following options are available:
-f-h-imv to write a prompt to standard error
      before moving a file that would overwrite an existing file. If the
      response from the standard input begins with the character ``y'', the move
      is attempted.-vmv to be verbose, showing files as they are
      processed.The last of any -f or
    -i options is the one which affects
    mv's behavior.
It is an error for any of the source operands to specify a nonexistent file or directory.
It is an error for the source operand to specify a directory if the target exists and is not a directory.
If the destination path does not have a mode which permits
    writing, mv prompts the user for confirmation as
    specified for the -i option.
Should the rename(2)
    call fail because source and
    target are on different file systems,
    mv will remove the destination file, copy the source
    file to the destination, and then remove the source. The effect is roughly
    equivalent to:
rm -f destination_path && \ cp -PRp source_file destination_path && \ rm -rf source_file
mv utility exits 0 on success,
  and >0 if an error occurs.
mv utility is expected to be IEEE
  Std 1003.2 (“POSIX.2”) compatible.
The -h and -v
    options are extensions to IEEE Std 1003.2
    (“POSIX.2”).
mv utility appeared in
