765 <div class="paragraph"><p>You can think of this as a set operation. Commits reachable from any of
766 the commits given on the command line form a set, and then commits reachable
767 from any of the ones given with <em>&#94;</em> in front are subtracted from that
768 set. The remaining commits are what comes out in the command&#8217;s output.
769 Various other options and paths parameters can be used to further limit the
770 result.</p></div>
771 <div class="paragraph"><p>Thus, the following command:</p></div>
772 <div class="listingblock">
773 <div class="content">
774 <pre><code>$ git log foo bar ^baz</code></pre>
775 </div></div>
776 <div class="paragraph"><p>means "list all the commits which are reachable from <em>foo</em> or <em>bar</em>, but
777 not from <em>baz</em>".</p></div>
778 <div class="paragraph"><p>A special notation "<em>&lt;commit1&gt;</em>..<em>&lt;commit2&gt;</em>" can be used as a
779 short-hand for "^<em>&lt;commit1&gt;</em> <em>&lt;commit2&gt;</em>". For example, either of
780 the following may be used interchangeably:</p></div>
781 <div class="listingblock">
782 <div class="content">
783 <pre><code>$ git log origin..HEAD
784 $ git log HEAD ^origin</code></pre>
785 </div></div>
786 <div class="paragraph"><p>Another special notation is "<em>&lt;commit1&gt;</em>&#8230;<em>&lt;commit2&gt;</em>" which is useful
787 for merges. The resulting set of commits is the symmetric difference
788 between the two operands. The following two commands are equivalent:</p></div>
789 <div class="listingblock">
790 <div class="content">
791 <pre><code>$ git log A B --not $(git merge-base --all A B)
792 $ git log A...B</code></pre>
793 </div></div>
794 <div class="paragraph"><p>The command takes options applicable to the <a href="git-rev-list.html">git-rev-list(1)</a>
795 command to control what is shown and how, and options applicable to
796 the <a href="git-diff.html">git-diff(1)</a> command to control how the changes

1839 to never drop all parents that we are TREESAME to.

1844 If after this parent rewriting, <code>C'</code> is a root or merge commit (has

1899 <div class="paragraph"><p>As an example use case, consider the following commit history:</p></div>
1900 <div class="listingblock">
1901 <div class="content">
1902 <pre><code> D---E-------F
1903 / \ \
1904 B---C---G---H---I---J
1906 A-------K---------------L--M</code></pre>
1907 </div></div>
1908 <div class="paragraph"><p>A regular <em>D..M</em> computes the set of commits that are ancestors of <code>M</code>,
1909 but excludes the ones that are ancestors of <code>D</code>. This is useful to see
1910 what happened to the history leading to <code>M</code> since <code>D</code>, in the sense
1911 that &#8220;what does <code>M</code> have that did not exist in <code>D</code>&#8221;. The result in this
1912 example would be all the commits, except <code>A</code> and <code>B</code> (and <code>D</code> itself,
1913 of course).</p></div>
1914 <div class="paragraph"><p>When we want to find out what commits in <code>M</code> are contaminated with the
1915 bug introduced by <code>D</code> and need fixing, however, we might want to view
1916 only the subset of <em>D..M</em> that are actually descendants of <code>D</code>, i.e.
1917 excluding <code>C</code> and <code>K</code>. This is exactly what the <code>--ancestry-path</code>
1918 option does. Applied to the <em>D..M</em> range, it results in:</p></div>
1919 <div class="listingblock">
1920 <div class="content">
1921 <pre><code> E-------F
1923 G---H---I---J

1927 <div class="paragraph"><p>We can also use <code>--ancestry-path=D</code> instead of <code>--ancestry-path</code> which
1928 means the same thing when applied to the <em>D..M</em> range but is just more
1929 explicit.</p></div>
1930 <div class="paragraph"><p>If we instead are interested in a given topic within this range, and all
1931 commits affected by that topic, we may only want to view the subset of
1932 <code>D..M</code> which contain that topic in their ancestry path. So, using
1933 <code>--ancestry-path=H D..M</code> for example would result in:</p></div>

1948 </dl></div>
1949 <div class="paragraph"><p>Before discussing another option, <code>--show-pulls</code>, we need to
1950 create a new example history.</p></div>
1951 <div class="paragraph"><p>A common problem users face when looking at simplified history is that a
1952 commit they know changed a file somehow does not appear in the file&#8217;s
1953 simplified history. Let&#8217;s demonstrate a new example and show how options
1954 such as <code>--full-history</code> and <code>--simplify-merges</code> works in that case:</p></div>
1955 <div class="listingblock">
1956 <div class="content">
1957 <pre><code> .-A---M-----C--N---O---P
1958 / / \ \ \/ / /
1959 I B \ R-'`-Z' /
1960 \ / \/ /
1961 \ / /\ /
1962 `---X--' `---Y--'</code></pre>
1963 </div></div>
1964 <div class="paragraph"><p>For this example, suppose <code>I</code> created <code>file.txt</code> which was modified by
1965 <code>A</code>, <code>B</code>, and <code>X</code> in different ways. The single-parent commits <code>C</code>, <code>Z</code>,
1966 and <code>Y</code> do not change <code>file.txt</code>. The merge commit <code>M</code> was created by
1967 resolving the merge conflict to include both changes from <code>A</code> and <code>B</code>
1968 and hence is not TREESAME to either. The merge commit <code>R</code>, however, was
1969 created by ignoring the contents of <code>file.txt</code> at <code>M</code> and taking only
1970 the contents of <code>file.txt</code> at <code>X</code>. Hence, <code>R</code> is TREESAME to <code>X</code> but not
1971 <code>M</code>. Finally, the natural merge resolution to create <code>N</code> is to take the
1972 contents of <code>file.txt</code> at <code>R</code>, so <code>N</code> is TREESAME to <code>R</code> but not <code>C</code>.
1973 The merge commits <code>O</code> and <code>P</code> are TREESAME to their first parents, but
1974 not to their second parents, <code>Z</code> and <code>Y</code> respectively.</p></div>
1975 <div class="paragraph"><p>When using the default mode, <code>N</code> and <code>R</code> both have a TREESAME parent, so
1976 those edges are walked and the others are ignored. The resulting history
1977 graph is:</p></div>
1978 <div class="listingblock">
1979 <div class="content">
1980 <pre><code> I---X</code></pre>
1981 </div></div>
1982 <div class="paragraph"><p>When using <code>--full-history</code>, Git walks every edge. This will discover
1983 the commits <code>A</code> and <code>B</code> and the merge <code>M</code>, but also will reveal the
1984 merge commits <code>O</code> and <code>P</code>. With parent rewriting, the resulting graph is:</p></div>
1985 <div class="listingblock">
1986 <div class="content">
1987 <pre><code> .-A---M--------N---O---P
1988 / / \ \ \/ / /
1989 I B \ R-'`--' /
1990 \ / \/ /
1991 \ / /\ /
1992 `---X--' `------'</code></pre>
1993 </div></div>
1994 <div class="paragraph"><p>Here, the merge commits <code>O</code> and <code>P</code> contribute extra noise, as they did
1995 not actually contribute a change to <code>file.txt</code>. They only merged a topic
1996 that was based on an older version of <code>file.txt</code>. This is a common
1997 issue in repositories using a workflow where many contributors work in
1998 parallel and merge their topic branches along a single trunk: many
1999 unrelated merges appear in the <code>--full-history</code> results.</p></div>
2000 <div class="paragraph"><p>When using the <code>--simplify-merges</code> option, the commits <code>O</code> and <code>P</code>
2001 disappear from the results. This is because the rewritten second parents
2002 of <code>O</code> and <code>P</code> are reachable from their first parents. Those edges are
2003 removed and then the commits look like single-parent commits that are
2004 TREESAME to their parent. This also happens to the commit <code>N</code>, resulting
2005 in a history view as follows:</p></div>
2006 <div class="listingblock">
2007 <div class="content">
2008 <pre><code> .-A---M--.
2009 / / \
2010 I B R
2011 \ / /
2012 \ / /
2013 `---X--'</code></pre>
2014 </div></div>
2015 <div class="paragraph"><p>In this view, we see all of the important single-parent changes from
2016 <code>A</code>, <code>B</code>, and <code>X</code>. We also see the carefully-resolved merge <code>M</code> and the
2017 not-so-carefully-resolved merge <code>R</code>. This is usually enough information
2018 to determine why the commits <code>A</code> and <code>B</code> "disappeared" from history in
2019 the default view. However, there are a few issues with this approach.</p></div>
2020 <div class="paragraph"><p>The first issue is performance. Unlike any previous option, the
2021 <code>--simplify-merges</code> option requires walking the entire commit history
2022 before returning a single result. This can make the option difficult to
2023 use for very large repositories.</p></div>
2024 <div class="paragraph"><p>The second issue is one of auditing. When many contributors are working
2025 on the same repository, it is important which merge commits introduced
2026 a change into an important branch. The problematic merge <code>R</code> above is
2027 not likely to be the merge commit that was used to merge into an
2028 important branch. Instead, the merge <code>N</code> was used to merge <code>R</code> and <code>X</code>
2029 into the important branch. This commit may have information about why
2030 the change <code>X</code> came to override the changes from <code>A</code> and <code>B</code> in its
2031 commit message.</p></div>

2038 In addition to the commits shown in the default history, show
2039 each merge commit that is not TREESAME to its first parent but
2040 is TREESAME to a later parent.
2041 </p>
2042 <div class="paragraph"><p>When a merge commit is included by <code>--show-pulls</code>, the merge is
2043 treated as if it "pulled" the change from another branch. When using
2044 <code>--show-pulls</code> on this example (and no other options) the resulting
2045 graph is:</p></div>
2046 <div class="listingblock">
2047 <div class="content">
2048 <pre><code> I---X---R---N</code></pre>
2049 </div></div>
2050 <div class="paragraph"><p>Here, the merge commits <code>R</code> and <code>N</code> are included because they pulled
2051 the commits <code>X</code> and <code>R</code> into the base branch, respectively. These
2052 merges are the reason the commits <code>A</code> and <code>B</code> do not appear in the
2053 default history.</p></div>
2054 <div class="paragraph"><p>When <code>--show-pulls</code> is paired with <code>--simplify-merges</code>, the
2055 graph includes all of the necessary information:</p></div>

2065 <div class="paragraph"><p>Notice that since <code>M</code> is reachable from <code>R</code>, the edge from <code>N</code> to <code>M</code>

3413 case-insensitively and trailing colon is optional. If option is
3414 given multiple times trailer lines matching any of the keys are
3415 shown. This option automatically enables the <code>only</code> option so that
3416 non-trailer lines in the trailer block are hidden. If that is not
3417 desired it can be disabled with <code>only=false</code>. E.g.,
3418 <code>%(trailers:key=Reviewed-by)</code> shows trailer lines with key

3432 terminated with a line feed character. The string &lt;sep&gt; may contain
3433 the literal formatting codes described above. To use comma as
3434 separator one must use <code>%x2C</code> as it would otherwise be parsed as
3435 next option. E.g., <code>%(trailers:key=Ticket,separator=%x2C )</code>

3504 provides "terminator" semantics instead of "separator" semantics. In

3506 newline) appended, rather than a separator placed between entries.
3507 This means that the final entry of a single-line format will be properly
3508 terminated with a new line, just as the "oneline" format does.

3522 <div class="paragraph"><p>In addition, any unrecognized string that has a <code>%</code> in it is interpreted

5167 was created for review of merge commit changes, and was not

5181 added to B), or <code>" "</code> (space&#8201;&#8212;&#8201;unchanged) prefix, this format
5182 compares two or more files file1, file2,&#8230; with one file X, and
5183 shows how X differs from each of fileN. One column for each of
5184 fileN is prepended to the output line to note how X&#8217;s line is
5185 different from it.</p></div>
5186 <div class="paragraph"><p>A <code>-</code> character in the column N means that the line appears in

5188 in the column N means that the line appears in the result,
5189 and fileN does not have that line (in other words, the line was
5190 added, from the point of view of that parent).</p></div>
5191 <div class="paragraph"><p>In the above example output, the function signature was changed
5192 from both files (hence two <code>-</code> removals from both file1 and
5193 file2, plus <code>++</code> to mean one line that was added does not appear
5194 in either file1 or file2). Also eight other lines are the same
5195 from file1 but do not appear in file2 (hence prefixed with <code>+</code>).</p></div>

5199 two unresolved merge parents with the working tree file

5308 <div class="sectionbody">
5309 <div class="paragraph"><p>Git is to some extent character encoding agnostic.</p></div>
5310 <div class="ulist"><ul>
5311 <li>
5313 The contents of the blob objects are uninterpreted sequences
5314 of bytes. There is no encoding translation at the core
5315 level.
5316 </p>
5317 </li>
5318 <li>
5320 Path names are encoded in UTF-8 normalization form C. This
5321 applies to tree objects, the index file, ref names, as well as
5322 path names in command line arguments, environment variables
5323 and config files (<code>.git/config</code> (see <a href="git-config.html">git-config(1)</a>),
5324 <a href="gitignore.html">gitignore(5)</a>, <a href="gitattributes.html">gitattributes(5)</a> and
5325 <a href="gitmodules.html">gitmodules(5)</a>).
5326 </p>
5327 <div class="paragraph"><p>Note that Git at the core level treats path names simply as
5328 sequences of non-NUL bytes, there are no path name encoding
5329 conversions (except on Mac and Windows). Therefore, using
5330 non-ASCII path names will mostly work even on platforms and file
5331 systems that use legacy extended ASCII encodings. However,
5332 repositories created on such systems will not work properly on
5333 UTF-8-based systems (e.g. Linux, Mac, Windows) and vice versa.
5334 Additionally, many Git-based tools simply assume path names to
5335 be UTF-8 and will fail to display other encodings correctly.</p></div>
5336 </li>
5337 <li>
5339 Commit log messages are typically encoded in UTF-8, but other
5340 extended ASCII encodings are also supported. This includes
5341 ISO-8859-x, CP125x and many others, but <em>not</em> UTF-16/32,
5342 EBCDIC and CJK multi-byte encodings (GBK, Shift-JIS, Big5,
5343 EUC-x, CP9xx etc.).
5344 </p>
5345 </li>
5346 </ul></div>
5347 <div class="paragraph"><p>Although we encourage that the commit log messages are encoded
5348 in UTF-8, both the core and Git Porcelain are designed not to
5349 force UTF-8 on projects. If all participants of a particular
5350 project find it more convenient to use legacy encodings, Git
5351 does not forbid it. However, there are a few things to keep in
5352 mind.</p></div>
5353 <div class="olist arabic"><ol class="arabic">
5354 <li>
5356 <em>git commit</em> and <em>git commit-tree</em> issues
5357 a warning if the commit log message given to it does not look
5358 like a valid UTF-8 string, unless you explicitly say your
5359 project uses a legacy encoding. The way to say this is to
5360 have <code>i18n.commitEncoding</code> in <code>.git/config</code> file, like this:
5361 </p>
5362 <div class="listingblock">
5363 <div class="content">

5368 of <code>i18n.commitEncoding</code> in its <code>encoding</code> header. This is to
5369 help other people who look at them later. Lack of this header
5370 implies that the commit log message is encoded in UTF-8.</p></div>
5371 </li>
5372 <li>
5374 <em>git log</em>, <em>git show</em>, <em>git blame</em> and friends look at the
5375 <code>encoding</code> header of a commit object, and try to re-code the
5376 log message into UTF-8 unless otherwise specified. You can
5377 specify the desired output encoding with
5378 <code>i18n.logOutputEncoding</code> in <code>.git/config</code> file, like this:
