MV(1)                           General Commands Manual                          MV(1)

NAME
     mv – move files

SYNOPSIS
     mv [-f | -i | -n] [-hv] source target
     mv [-f | -i | -n] [-v] source ... directory

DESCRIPTION
     In its first form, the 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.

     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      Do not prompt for confirmation before overwriting the destination path.
             (The -f option overrides any previous -i or -n options.)

     -h      If the target operand is a symbolic link to a directory, do not follow
             it.  This causes the mv utility to rename the file source to the
             destination path target rather than moving source into the directory
             referenced by target.

     -i      Cause mv 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’ or ‘Y’, the move is attempted.  (The
             -i option overrides any previous -f or -n options.)

     -n      Do not overwrite an existing file.  (The -n option overrides any previous
             -f or -i options.)

     -v      Cause mv to be verbose, showing files after they are moved.

     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.

     As the rename(2) call does not work across file systems, mv uses cp(1) and rm(1)
     to accomplish the move.  The effect is equivalent to:

           rm -f destination_path && \
           cp -pRP source_file destination && \
           rm -rf source_file

EXIT STATUS
     The mv utility exits 0 on success, and >0 if an error occurs.

     The command "mv dir/afile dir" will abort with an error message.

LEGACY DIAGNOSTICS
     In legacy mode, the command "mv dir/afile dir" will fail silently, returning an
     exit code of 0.

     For more information about legacy mode, see compat(5).

EXAMPLES
     Rename file foo to bar, overwriting bar if it already exists:

           $ mv -f foo bar
:
