 <h2>NAME</h2>
 <div class="sectionbody">
 <p>git-checkout-index -
  Copy files from the index to the working tree
 </p>
 </div>
 </div>
 <h2>SYNOPSIS</h2>
 <div class="sectionbody">
 <div class="verseblock">
 <div class="content"><em>git-checkout-index</em> [-u] [-q] [-a] [-f] [-n] [--prefix=&lt;string&gt;]
  [--stage=&lt;number&gt;|all]
  [--temp]
  [-z] [--stdin]
  [--] [&lt;file&gt;]*</div></div>
 </div>
 <h2>DESCRIPTION</h2>
 <div class="sectionbody">
 <p>Will copy all files listed from the index to the working directory
 (not overwriting existing files).</p>
 </div>
 <h2>OPTIONS</h2>
 <div class="sectionbody">
 <dl>
 <dt>
 -u|--index
 </dt>
 <dd>
 <p>
  update stat information for the checked out entries in
  the index file.
 </p>
 </dd>
 <dt>
 -q|--quiet
 </dt>
 <dd>
 <p>
  be quiet if files exist or are not in the index
 </p>
 </dd>
 <dt>
 -f|--force
 </dt>
 <dd>
 <p>
  forces overwrite of existing files
 </p>
 </dd>
 <dt>
 -a|--all
 </dt>
 <dd>
 <p>
  checks out all files in the index. Cannot be used
  together with explicit filenames.
 </p>
 </dd>
 <dt>
 -n|--no-create
 </dt>
 <dd>
 <p>
  Don't checkout new files, only refresh files already checked
  out.
 </p>
 </dd>
 <dt>
 --prefix=&lt;string&gt;
 </dt>
 <dd>
 <p>
  When creating files, prepend &lt;string&gt; (usually a directory
  including a trailing /)
 </p>
 </dd>
 <dt>
 --stage=&lt;number&gt;|all
 </dt>
 <dd>
 <p>
  Instead of checking out unmerged entries, copy out the
  files from named stage. &lt;number&gt; must be between 1 and 3.
  Note: --stage=all automatically implies --temp.
 </p>
 </dd>
 <dt>
 --temp
 </dt>
 <dd>
 <p>
  Instead of copying the files to the working directory
  write the content to temporary files. The temporary name
  associations will be written to stdout.
 </p>
 </dd>
 <dt>
 --stdin
 </dt>
 <dd>
 <p>
  Instead of taking list of paths from the command line,
  read list of paths from the standard input. Paths are
  separated by LF (i.e. one path per line) by default.
 </p>
 </dd>
 <dt>
 -z
 </dt>
 <dd>
 <p>
  Only meaningful with <tt>--stdin</tt>; paths are separated with
  NUL character instead of LF.
 </p>
 </dd>
 <dt>
 --
 </dt>
 <dd>
 <p>
  Do not interpret any more arguments as options.
 </p>
 </dd>
 </dl>
 <p>The order of the flags used to matter, but not anymore.</p>
 <p>Just doing <tt>git-checkout-index</tt> does nothing. You probably meant
 <tt>git-checkout-index -a</tt>. And if you want to force it, you want
 <tt>git-checkout-index -f -a</tt>.</p>
 <p>Intuitiveness is not the goal here. Repeatability is. The reason for
 the "no arguments means no work" behavior is that from scripts you are
 supposed to be able to do:</p>
 <div class="listingblock">
 <div class="content">
 <pre><tt>$ find . -name '*.h' -print0 | xargs -0 git-checkout-index -f --</tt></pre>
 </div></div>
 <p>which will force all existing <tt>*.h</tt> files to be replaced with their
 cached copies. If an empty command line implied "all", then this would
 force-refresh everything in the index, which was not the point. But
 since git-checkout-index accepts --stdin it would be faster to use:</p>
 <div class="listingblock">
 <div class="content">
 <pre><tt>$ find . -name '*.h' -print0 | git-checkout-index -f -z --stdin</tt></pre>
 </div></div>
 <p>The <tt>--</tt> is just a good idea when you know the rest will be filenames;
 it will prevent problems with a filename of, for example, <tt>-a</tt>.
 Using <tt>--</tt> is probably a good policy in scripts.</p>
 </div>
 <h2>Using --temp or --stage=all</h2>
 <div class="sectionbody">
 <p>When <tt>--temp</tt> is used (or implied by <tt>--stage=all</tt>)
 <tt>git-checkout-index</tt> will create a temporary file for each index
 entry being checked out. The index will not be updated with stat
 information. These options can be useful if the caller needs all
 stages of all unmerged entries so that the unmerged files can be
 processed by an external merge tool.</p>
 <p>A listing will be written to stdout providing the association of
 temporary file names to tracked path names. The listing format
 has two variations:</p>
 <ol>
 <li>
 <p>
 tempname TAB path RS
 </p>
 <p>The first format is what gets used when <tt>--stage</tt> is omitted or
 is not <tt>--stage=all</tt>. The field tempname is the temporary file
 name holding the file content and path is the tracked path name in
 the index. Only the requested entries are output.</p>
 </li>
 <li>
 <p>
 stage1temp SP stage2temp SP stage3tmp TAB path RS
 </p>
 <p>The second format is what gets used when <tt>--stage=all</tt>. The three
 stage temporary fields (stage1temp, stage2temp, stage3temp) list the
 name of the temporary file if there is a stage entry in the index
 or <tt>.</tt> if there is no stage entry. Paths which only have a stage 0
 entry will always be omitted from the output.</p>
 </li>
 </ol>
 <p>In both formats RS (the record separator) is newline by default
 but will be the null byte if -z was passed on the command line.
 The temporary file names are always safe strings; they will never
 contain directory separators or whitespace characters. The path
 field is always relative to the current directory and the temporary
 file names are always relative to the top level directory.</p>
 <p>If the object being copied out to a temporary file is a symbolic
 link the content of the link will be written to a normal file. It is
 up to the end-user or the Porcelain to make use of this information.</p>
 </div>
 <h2>EXAMPLES</h2>
 <div class="sectionbody">
 <dl>
 <dt>
 To update and refresh only the files already checked out
 </dt>
 <dd>
 <div class="listingblock">
 <div class="content">
 <pre><tt>$ git-checkout-index -n -f -a &amp;&amp; git-update-index --ignore-missing --refresh</tt></pre>
 </div></div>
 </dd>
 <dt>
 Using <tt>git-checkout-index</tt> to "export an entire tree"
 </dt>
 <dd>
 <p>
  The prefix ability basically makes it trivial to use
  <tt>git-checkout-index</tt> as an "export as tree" function.
  Just read the desired tree into the index, and do:
 </p>
 <div class="listingblock">
 <div class="content">
 <pre><tt>$ git-checkout-index --prefix=git-export-dir/ -a</tt></pre>
 </div></div>
 <p><tt>git-checkout-index</tt> will "export" the index into the specified
 directory.</p>
 <p>The final "/" is important. The exported name is literally just
 prefixed with the specified string. Contrast this with the
 following example.</p>
 </dd>
 <dt>
 Export files with a prefix
 </dt>
 <dd>
 <div class="listingblock">
 <div class="content">
 <pre><tt>$ git-checkout-index --prefix=.merged- Makefile</tt></pre>
 </div></div>
 <p>This will check out the currently cached copy of <tt>Makefile</tt>
 into the file <tt>.merged-Makefile</tt>.</p>
 </dd>
 </dl>

	</p>
	</dd>
	<dt>
	--
	</dt>
	<dd>
	<p>
	Do not interpret any more arguments as options.
	</p>
	</dd>
	</dl>
	<p>The order of the flags used to matter, but not anymore.</p>
	<p>Just doing <tt>git-checkout-index</tt> does nothing. You probably meant
	<tt>git-checkout-index -a</tt>. And if you want to force it, you want
	<tt>git-checkout-index -f -a</tt>.</p>
	<p>Intuitiveness is not the goal here. Repeatability is. The reason for
	the "no arguments means no work" behavior is that from scripts you are
	supposed to be able to do:</p>
	<div class="listingblock">
	<div class="content">
	<pre><tt>$ find . -name '*.h' -print0 \| xargs -0 git-checkout-index -f --</tt></pre>
	</div></div>
	<p>which will force all existing <tt>*.h</tt> files to be replaced with their
	cached copies. If an empty command line implied "all", then this would
	force-refresh everything in the index, which was not the point. But
	since git-checkout-index accepts --stdin it would be faster to use:</p>
	<div class="listingblock">
	<div class="content">
	<pre><tt>$ find . -name '*.h' -print0 \| git-checkout-index -f -z --stdin</tt></pre>
	</div></div>
	<p>The <tt>--</tt> is just a good idea when you know the rest will be filenames;
	it will prevent problems with a filename of, for example, <tt>-a</tt>.
	Using <tt>--</tt> is probably a good policy in scripts.</p>
	</div>
	<h2>Using --temp or --stage=all</h2>
	<div class="sectionbody">
	<p>When <tt>--temp</tt> is used (or implied by <tt>--stage=all</tt>)
	<tt>git-checkout-index</tt> will create a temporary file for each index
	entry being checked out. The index will not be updated with stat
	information. These options can be useful if the caller needs all
	stages of all unmerged entries so that the unmerged files can be
	processed by an external merge tool.</p>
	<p>A listing will be written to stdout providing the association of
	temporary file names to tracked path names. The listing format
	has two variations:</p>
	<ol>
	<li>
	<p>
	tempname TAB path RS
	</p>
	<p>The first format is what gets used when <tt>--stage</tt> is omitted or
	is not <tt>--stage=all</tt>. The field tempname is the temporary file
	name holding the file content and path is the tracked path name in
	the index. Only the requested entries are output.</p>
	</li>
	<li>
	<p>
	stage1temp SP stage2temp SP stage3tmp TAB path RS
	</p>
	<p>The second format is what gets used when <tt>--stage=all</tt>. The three
	stage temporary fields (stage1temp, stage2temp, stage3temp) list the
	name of the temporary file if there is a stage entry in the index
	or <tt>.</tt> if there is no stage entry. Paths which only have a stage 0
	entry will always be omitted from the output.</p>
	</li>
	</ol>
	<p>In both formats RS (the record separator) is newline by default
	but will be the null byte if -z was passed on the command line.
	The temporary file names are always safe strings; they will never
	contain directory separators or whitespace characters. The path
	field is always relative to the current directory and the temporary
	file names are always relative to the top level directory.</p>
	<p>If the object being copied out to a temporary file is a symbolic
	link the content of the link will be written to a normal file. It is
	up to the end-user or the Porcelain to make use of this information.</p>

	<h2>EXAMPLES</h2>
	<div class="sectionbody">
	<dl>
	<dt>
	To update and refresh only the files already checked out
	</dt>
	<dd>
	<div class="listingblock">
	<div class="content">
	<pre><tt>$ git-checkout-index -n -f -a && git-update-index --ignore-missing --refresh</tt></pre>
	</div></div>
	</dd>
	<dt>
	Using <tt>git-checkout-index</tt> to "export an entire tree"
	</dt>
	<dd>
	<p>
	The prefix ability basically makes it trivial to use
	<tt>git-checkout-index</tt> as an "export as tree" function.
	Just read the desired tree into the index, and do:
	</p>
	<div class="listingblock">
	<div class="content">
	<pre><tt>$ git-checkout-index --prefix=git-export-dir/ -a</tt></pre>
	</div></div>
	<p><tt>git-checkout-index</tt> will "export" the index into the specified
	directory.</p>
	<p>The final "/" is important. The exported name is literally just
	prefixed with the specified string. Contrast this with the
	following example.</p>
	</dd>
	<dt>
	Export files with a prefix
	</dt>
	<dd>
	<div class="listingblock">
	<div class="content">
	<pre><tt>$ git-checkout-index --prefix=.merged- Makefile</tt></pre>
	</div></div>
	<p>This will check out the currently cached copy of <tt>Makefile</tt>
	into the file <tt>.merged-Makefile</tt>.</p>
	</dd>
	</dl>
