 962         Generate a diffstat. By default, as much space as necessary
 963         will be used for the filename part, and the rest for the graph
 964         part. Maximum width defaults to terminal width, or 80 columns
 965         if not connected to a terminal, and can be overridden by
 966         <code>&lt;width&gt;</code>. The width of the filename part can be limited by
 967         giving another width <code>&lt;name-width&gt;</code> after a comma or by setting
 968         <code>diff.statNameWidth=&lt;width&gt;</code>. The width of the graph part can be
 969         limited by using <code>--stat-graph-width=&lt;width&gt;</code> or by setting
 970         <code>diff.statGraphWidth=&lt;width&gt;</code>. Using <code>--stat</code> or
 971         <code>--stat-graph-width</code> affects all commands generating a stat graph,

1595         For performance reasons, by default, <code>-C</code> option finds copies only
1596         if the original file of the copy was modified in the same
1597         changeset.  This flag makes the command
1598         inspect unmodified files as candidates for the source of

1628         The <code>-M</code> and <code>-C</code> options involve some preliminary steps that
1629         can detect subsets of renames/copies cheaply, followed by an
1630         exhaustive fallback portion that compares all remaining
1631         unpaired destinations to all relevant sources.  (For renames,
1632         only remaining unpaired sources are relevant; for copies, all
1633         original sources are relevant.)  For N sources and
1634         destinations, this exhaustive check is O(N^2).  This option
1635         prevents the exhaustive portion of rename/copy detection from

2515 It is followed by one or more extended header lines
2516      (this example shows a merge with two parents):
2517 </p>
2518 <div class="literalblock">
2519 <div class="content">
2520 <pre><code>index &lt;hash&gt;,&lt;hash&gt;..&lt;hash&gt;
2521 mode &lt;mode&gt;,&lt;mode&gt;..&lt;mode&gt;
2522 new file mode &lt;mode&gt;
2523 deleted file mode &lt;mode&gt;,&lt;mode&gt;</code></pre>
2524 </div></div>
2525 <div class="paragraph"><p>The <code>mode &lt;mode&gt;,&lt;mode&gt;..&lt;mode&gt;</code> line appears only if at least one of
2526 the &lt;mode&gt; is different from the rest. Extended headers with
2527 information about detected content movement (renames and
2528 copying detection) are designed to work with the diff of two
2529 &lt;tree-ish&gt; and are not used by combined diff format.</p></div>
2530 </li>
2531 <li>
2532 <p>
2533 It is followed by a two-line from-file/to-file header:
2534 </p>
2535 <div class="literalblock">
2536 <div class="content">
2537 <pre><code>--- a/file
2538 +++ b/file</code></pre>
2539 </div></div>
2540 <div class="paragraph"><p>Similar to the two-line header for the traditional <em>unified</em> diff
2541 format, <code>/dev/null</code> is used to signal created or deleted
2542 files.</p></div>
2543 <div class="paragraph"><p>However, if the --combined-all-paths option is provided, instead of a
2544 two-line from-file/to-file, you get an N+1 line from-file/to-file header,
2545 where N is the number of parents in the merge commit:</p></div>
2546 <div class="literalblock">
2547 <div class="content">
2548 <pre><code>--- a/file
2549 --- a/file
2550 --- a/file
2551 +++ b/file</code></pre>
2552 </div></div>
2553 <div class="paragraph"><p>This extended format can be useful if rename or copy detection is
2554 active, to allow you to see the original name of the file in different
2555 parents.</p></div>
2556 </li>
2557 <li>
2558 <p>
2559 Chunk header format is modified to prevent people from
2560      accidentally feeding it to <code>patch -p1</code>. Combined diff format
2561      was created for review of merge commit changes, and was not
2562      meant to be applied. The change is similar to the change in the
2563      extended <em>index</em> header:
2564 </p>
2565 <div class="literalblock">
2566 <div class="content">
2567 <pre><code>@@@ &lt;from-file-range&gt; &lt;from-file-range&gt; &lt;to-file-range&gt; @@@</code></pre>
2568 </div></div>
2569 <div class="paragraph"><p>There are (number of parents + 1) <code>@</code> characters in the chunk
2570 header for combined diff format.</p></div>
2571 </li>
2572 </ol></div>
2573 <div class="paragraph"><p>Unlike the traditional <em>unified</em> diff format, which shows two
2574 files A and B with a single column that has <code>-</code> (minus&#8201;&#8212;&#8201;appears in A but removed in B), <code>+</code> (plus&#8201;&#8212;&#8201;missing in A but
2575 added to B), or <code>" "</code> (space&#8201;&#8212;&#8201;unchanged) prefix, this format
2576 compares two or more files file1, file2,&#8230; with one file X, and
2577 shows how X differs from each of fileN.  One column for each of
2578 fileN is prepended to the output line to note how X&#8217;s line is
2579 different from it.</p></div>
2580 <div class="paragraph"><p>A <code>-</code> character in the column N means that the line appears in
2581 fileN but it does not appear in the result.  A <code>+</code> character
2582 in the column N means that the line appears in the result,
2583 and fileN does not have that line (in other words, the line was
2584 added, from the point of view of that parent).</p></div>
2585 <div class="paragraph"><p>In the above example output, the function signature was changed
2586 from both files (hence two <code>-</code> removals from both file1 and
2587 file2, plus <code>++</code> to mean one line that was added does not appear
2588 in either file1 or file2).  Also, eight other lines are the same
2589 from file1 but do not appear in file2 (hence prefixed with <code>+</code>).</p></div>
2590 <div class="paragraph"><p>When shown by <code>git diff-tree -c</code>, it compares the parents of a
2591 merge commit with the merge result (i.e. file1..fileN are the
2592 parents).  When shown by <code>git diff-files -c</code>, it compares the
2593 two unresolved merge parents with the working tree file
2594 (i.e. file1 is stage 2 aka "our version", file2 is stage 3 aka
2595 "their version").</p></div>

2601 <div class="paragraph"><p>The <code>--summary</code> option describes newly added, deleted, renamed and

2604 <code>-p</code>, and are meant for human consumption.</p></div>
2605 <div class="paragraph"><p>When showing a change that involves a rename or a copy, <code>--stat</code> output
2606 formats the pathnames compactly by combining common prefix and suffix of
2607 the pathnames.  For example, a change that moves <code>arch/i386/Makefile</code> to
2608 <code>arch/x86/Makefile</code> while modifying 4 lines will be shown like this:</p></div>
