MV(1)                       General Commands Manual                      MV(1)


NAME

     mv - move files


SYNOPSIS

     mv [-fi] source target
     mv [-fi] source ... directory


DESCRIPTION

     In its first form, the mv utility moves 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 the
     destination specified by the directory operand.  It is an error if the
     directory does not exist.  The destination path for each source operand
     is the pathname produced by the concatenation of the directory operand, a
     slash, and the final pathname component of the named file.

     In both forms, a source operand is skipped with an error message when the
     respective destination path is a non-empty directory, or when the source
     is a non-directory file but the destination path is a directory, or vice
     versa.

     The options are as follows:

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

     -i      Causes 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'', the move is
             attempted.  The -i option overrides any previous -f options.

     The mv utility moves symbolic links, not the files referenced by the
     links.

     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 the source and destination are on
     different file systems, mv will use cp(1) and rm(1) to accomplish the
     move.  The effect is equivalent to:

           $ rm -df -- destination_path && \
               cp -PRp -- source destination_path && \
               rm -rf -- source


EXIT STATUS

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


EXAMPLES

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

           $ mv -f foo bar

     Either of these commands will rename the file -f to bar, prompting for
     confirmation if bar already exists:

           $ mv -i -- -f bar
           $ mv -i ./-f bar


SEE ALSO

     cp(1), rm(1), rename(2), symlink(7)


STANDARDS

     The mv utility is compliant with the IEEE Std 1003.1-2008 (``POSIX.1'')
     specification.


HISTORY

     A mv command appeared in Version 1 AT&T UNIX.


CAVEATS

     In the second synopsis form, incompatible file types in source and
     directory cause partial moves.  For example, if f and g are non-directory
     files and d and d/f are directories, the command

           $ mv f g d

     will print an error message, leave f where it is, move g to d/g and
     return a non-zero exit status.
