<h1> Move Command </h1>
|
|
<h2>NAME</h2>
|
|
<p>mv -- move files</p>
|
|
|
|
<h2>SYNOPSIS</h2>
|
|
<p>mv [-f | -i | -n] [-v] source target</p>
|
|
<p>mv [-f | -i | -n] [-v] source ... directory</p>
|
|
|
|
<h2>DESCRIPTION</h2>
|
|
<p>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.</p>
|
|
|
|
<p>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.</p>
|
|
|
|
<p>The following options are available:</p>
|
|
|
|
<p>-f
|
|
|
|
<p>Do not prompt for confirmation before overwriting the destination path. (The -f option overrides any previous -i or -n options.)
|
|
|
|
<p>-i
|
|
|
|
<p>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.)
|
|
|
|
<p>-n
|
|
|
|
<p>Do not overwrite an existing file. (The -n option overrides any previous -f or -i options.)
|
|
|
|
<p>-v
|
|
|
|
<p>Cause mv to be verbose, showing files after they are moved.
|
|
|
|
<p>It is an error for either the source operand or the destination path to specify a directory unless both do.
|
|
|
|
<p>If the destination path does not have a mode which permits writing, mv prompts the user for confirmation as specified for the -i option.
|
|
|
|
<p>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:
|
|
<ul>
|
|
<li>rm -f destination_path && \</li>
|
|
<li>cp -pRP source_file destination && \</li>
|
|
<li>rm -rf source_file</li>
|
|
</ul>
|
|
|
|
<h2>DIAGNOSTICS</h2>
|
|
|
|
<p>The command "mv dir/afile dir" will abort with an error message.<p>
|
|
|
|
LEGACY DIAGNOSTICS
|
|
|
|
<p>In legacy mode, the command "mv dir/afile dir" will fail silently, returning an exit code of 0.<p>
|
|
|
|
<p>For more information about legacy mode, see compat(5).<p>
|
|
|
|
<h2>SEE ALSO</h2>
|
|
<ul>
|
|
<li>cp(1)</li>
|
|
<li>rm(1)</li>
|
|
<li>symlink(7)</li>
|
|
</ul>
|
|
<h2>COMPATIBILITY</h2>
|
|
|
|
<p>The -n and -v options are non-standard and their use in scripts is not recommended.<p>
|
|
|
|
<p>The mv utility now supports HFS+ Finder and Extended Attributes and
|
|
resource forks. The mv utility will no longer strip resource forks off of HFS files. For an alternative method, refer to cp(1).</p>
|
|
|
|
<h2>STANDARDS</h2>
|
|
|
|
<p>The mv utility is expected to be IEEE Std 1003.2 (``POSIX.2'') compatible.</p>
|
|
|
|
<h2>HISTORY</h2>
|
|
|
|
<p>A mv command appeared in Version 1 AT&T UNIX.</p>
