 </div>
 <h2 id="_description">DESCRIPTION</h2>
 <div class="sectionbody">
 <div class="paragraph"><p><em>git difftool</em> is a git command that allows you to compare and edit files
 between revisions using common diff tools. <em>git difftool</em> is a frontend
 to <em>git diff</em> and accepts the same options and arguments. See
 <a href="git-diff.html">git-diff(1)</a>.</p></div>
 </div>
 <h2 id="_options">OPTIONS</h2>
 <div class="sectionbody">
 <div class="dlist"><dl>
 <dt class="hdlist1">
 -y
 </dt>
 <dt class="hdlist1">
 --no-prompt
 </dt>
 <dd>
 <p>
  Do not prompt before launching a diff tool.
 </p>
 </dd>
 <dt class="hdlist1">
 --prompt
 </dt>
 <dd>
 <p>
  Prompt before each invocation of the diff tool.
  This is the default behaviour; the option is provided to
  override any configuration settings.
 </p>
 </dd>
 <dt class="hdlist1">
 -t &lt;tool&gt;
 </dt>
 <dt class="hdlist1">
 --tool=&lt;tool&gt;
 </dt>
 <dd>
 <p>
  Use the diff tool specified by &lt;tool&gt;.
  Valid merge tools are:
  araxis, bc3, diffuse, emerge, ecmerge, gvimdiff, kdiff3,
  kompare, meld, opendiff, p4merge, tkdiff, vimdiff and xxdiff.
 </p>
 <div class="paragraph"><p>If a diff tool is not specified, <em>git difftool</em>
 will use the configuration variable <tt>diff.tool</tt>. If the
 configuration variable <tt>diff.tool</tt> is not set, <em>git difftool</em>
 will pick a suitable default.</p></div>
 <div class="paragraph"><p>You can explicitly provide a full path to the tool by setting the
 configuration variable <tt>difftool.&lt;tool&gt;.path</tt>. For example, you
 can configure the absolute path to kdiff3 by setting
 <tt>difftool.kdiff3.path</tt>. Otherwise, <em>git difftool</em> assumes the
 tool is available in PATH.</p></div>
 <div class="paragraph"><p>Instead of running one of the known diff tools,
 <em>git difftool</em> can be customized to run an alternative program
 by specifying the command line to invoke in a configuration
 variable <tt>difftool.&lt;tool&gt;.cmd</tt>.</p></div>
 <div class="paragraph"><p>When <em>git difftool</em> is invoked with this tool (either through the
 <tt>-t</tt> or <tt>--tool</tt> option or the <tt>diff.tool</tt> configuration variable)
 the configured command line will be invoked with the following
 variables available: <tt>$LOCAL</tt> is set to the name of the temporary
 file containing the contents of the diff pre-image and <tt>$REMOTE</tt>
 is set to the name of the temporary file containing the contents
 of the diff post-image. <tt>$MERGED</tt> is the name of the file which is
 being compared. <tt>$BASE</tt> is provided for compatibility
 with custom merge tool commands and has the same value as <tt>$MERGED</tt>.</p></div>
 </dd>
 <dt class="hdlist1">
 -x &lt;command&gt;
 </dt>
 <dt class="hdlist1">
 --extcmd=&lt;command&gt;
 </dt>
 <dd>
 <p>
  Specify a custom command for viewing diffs.
  <em>git-difftool</em> ignores the configured defaults and runs
  <tt>$command $LOCAL $REMOTE</tt> when this option is specified.
  Additionally, <tt>$BASE</tt> is set in the environment.
 </p>
 </dd>
 <dt class="hdlist1">
 -g
 </dt>
 <dt class="hdlist1">
 --gui
 </dt>
 <dd>
 <p>
  When <em>git-difftool</em> is invoked with the <tt>-g</tt> or <tt>--gui</tt> option
  the default diff tool will be read from the configured
  <tt>diff.guitool</tt> variable instead of <tt>diff.tool</tt>.
 </p>
 </dd>
 </dl></div>
 <div class="paragraph"><p>See <a href="git-diff.html">git-diff(1)</a> for the full list of supported options.</p></div>
 </div>
 <h2 id="_config_variables">CONFIG VARIABLES</h2>
 <div class="sectionbody">

 difftool equivalents have not been defined.</p></div>

	<h2 id="_description">DESCRIPTION</h2>
	<div class="sectionbody">
	<div class="paragraph"><p><em>git difftool</em> is a git command that allows you to compare and edit files
	between revisions using common diff tools. <em>git difftool</em> is a frontend
	to <em>git diff</em> and accepts the same options and arguments. See
	<a href="git-diff.html">git-diff(1)</a>.</p></div>
	</div>
	<h2 id="_options">OPTIONS</h2>
	<div class="sectionbody">
	<div class="dlist"><dl>
	<dt class="hdlist1">
	-y
	</dt>
	<dt class="hdlist1">
	--no-prompt
	</dt>
	<dd>
	<p>
	Do not prompt before launching a diff tool.
	</p>
	</dd>
	<dt class="hdlist1">
	--prompt
	</dt>
	<dd>
	<p>
	Prompt before each invocation of the diff tool.
	This is the default behaviour; the option is provided to
	override any configuration settings.
	</p>
	</dd>
	<dt class="hdlist1">
	-t <tool>
	</dt>
	<dt class="hdlist1">
	--tool=<tool>
	</dt>
	<dd>
	<p>
	Use the diff tool specified by <tool>.
	Valid merge tools are:
	araxis, bc3, diffuse, emerge, ecmerge, gvimdiff, kdiff3,
	kompare, meld, opendiff, p4merge, tkdiff, vimdiff and xxdiff.
	</p>
	<div class="paragraph"><p>If a diff tool is not specified, <em>git difftool</em>
	will use the configuration variable <tt>diff.tool</tt>. If the
	configuration variable <tt>diff.tool</tt> is not set, <em>git difftool</em>
	will pick a suitable default.</p></div>
	<div class="paragraph"><p>You can explicitly provide a full path to the tool by setting the
	configuration variable <tt>difftool.<tool>.path</tt>. For example, you
	can configure the absolute path to kdiff3 by setting
	<tt>difftool.kdiff3.path</tt>. Otherwise, <em>git difftool</em> assumes the
	tool is available in PATH.</p></div>
	<div class="paragraph"><p>Instead of running one of the known diff tools,
	<em>git difftool</em> can be customized to run an alternative program
	by specifying the command line to invoke in a configuration
	variable <tt>difftool.<tool>.cmd</tt>.</p></div>
	<div class="paragraph"><p>When <em>git difftool</em> is invoked with this tool (either through the
	<tt>-t</tt> or <tt>--tool</tt> option or the <tt>diff.tool</tt> configuration variable)
	the configured command line will be invoked with the following
	variables available: <tt>$LOCAL</tt> is set to the name of the temporary
	file containing the contents of the diff pre-image and <tt>$REMOTE</tt>
	is set to the name of the temporary file containing the contents
	of the diff post-image. <tt>$MERGED</tt> is the name of the file which is
	being compared. <tt>$BASE</tt> is provided for compatibility
	with custom merge tool commands and has the same value as <tt>$MERGED</tt>.</p></div>

	<dt class="hdlist1">
	-x <command>
	</dt>
	<dt class="hdlist1">
	--extcmd=<command>
	</dt>
	<dd>
	<p>
	Specify a custom command for viewing diffs.
	<em>git-difftool</em> ignores the configured defaults and runs
	<tt>$command $LOCAL $REMOTE</tt> when this option is specified.
	Additionally, <tt>$BASE</tt> is set in the environment.
	</p>
	</dd>
	<dt class="hdlist1">
	-g
	</dt>
	<dt class="hdlist1">
	--gui
	</dt>
	<dd>
	<p>
	When <em>git-difftool</em> is invoked with the <tt>-g</tt> or <tt>--gui</tt> option
	the default diff tool will be read from the configured
	<tt>diff.guitool</tt> variable instead of <tt>diff.tool</tt>.
