 764 <div class="sectionbody">
 765 <div class="paragraph"><p>Adds a <em>replace</em> reference in <code>refs/replace/</code> namespace.</p></div>
 766 <div class="paragraph"><p>The name of the <em>replace</em> reference is the SHA-1 of the object that is
 767 replaced. The content of the <em>replace</em> reference is the SHA-1 of the
 768 replacement object.</p></div>
 769 <div class="paragraph"><p>The replaced object and the replacement object must be of the same type.
 770 This restriction can be bypassed using <code>-f</code>.</p></div>
 771 <div class="paragraph"><p>Unless <code>-f</code> is given, the <em>replace</em> reference must not yet exist.</p></div>
 772 <div class="paragraph"><p>There is no other restriction on the replaced and replacement objects.
 773 Merge commits can be replaced by non-merge commits and vice versa.</p></div>
 774 <div class="paragraph"><p>Replacement references will be used by default by all Git commands
 775 except those doing reachability traversal (prune, pack transfer and
 776 fsck).</p></div>
 777 <div class="paragraph"><p>It is possible to disable use of replacement references for any
 778 command using the <code>--no-replace-objects</code> option just after <em>git</em>.</p></div>
 779 <div class="paragraph"><p>For example if commit <em>foo</em> has been replaced by commit <em>bar</em>:</p></div>
 780 <div class="listingblock">
 781 <div class="content">
 782 <pre><code>$ git --no-replace-objects cat-file commit foo</code></pre>
 783 </div></div>
 784 <div class="paragraph"><p>shows information about commit <em>foo</em>, while:</p></div>

 787 <pre><code>$ git cat-file commit foo</code></pre>
 788 </div></div>
 789 <div class="paragraph"><p>shows information about commit <em>bar</em>.</p></div>
 790 <div class="paragraph"><p>The <code>GIT_NO_REPLACE_OBJECTS</code> environment variable can be set to
 791 achieve the same effect as the <code>--no-replace-objects</code> option.</p></div>

 826         Edit an object&#8217;s content interactively. The existing content
 827         for &lt;object&gt; is pretty-printed into a temporary file, an
 828         editor is launched on the file, and the result is parsed to
 829         create a new object of the same type as &lt;object&gt;. A
 830         replacement ref is then created to replace &lt;object&gt; with the
 831         newly created object. See <a href="git-var.html">git-var(1)</a> for details about
 832         how the editor will be chosen.

 839 <p>
 840         When editing, provide the raw object contents rather than
 841         pretty-printed ones. Currently this only affects trees, which
 842         will be shown in their binary form. This is harder to work with,
 843         but can help when repairing a tree that is so corrupted it
 844         cannot be pretty-printed. Note that you may need to configure
 845         your editor to cleanly read and write binary data.

 853         Create a graft commit. A new commit is created with the same

 855         [&lt;parent&gt;&#8230;] instead of &lt;commit&gt;'s parents. A replacement ref
 856         is then created to replace &lt;commit&gt; with the newly created
 857         commit. Use <code>--convert-graft-file</code> to convert a
 858         <code>$GIT_DIR/info/grafts</code> file and use replace refs instead.
