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

1815 resolving the merge conflict to include both changes from <code>A</code> and <code>B</code>
1816 and hence is not TREESAME to either. The merge commit <code>R</code>, however, was
1817 created by ignoring the contents of <code>file.txt</code> at <code>M</code> and taking only
1818 the contents of <code>file.txt</code> at <code>X</code>. Hence, <code>R</code> is TREESAME to <code>X</code> but not
1819 <code>M</code>. Finally, the natural merge resolution to create <code>N</code> is to take the
1820 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>.
1821 The merge commits <code>O</code> and <code>P</code> are TREESAME to their first parents, but

1831 the commits <code>A</code> and <code>B</code> and the merge <code>M</code>, but also will reveal the
1832 merge commits <code>O</code> and <code>P</code>. With parent rewriting, the resulting graph is:</p></div>

1838 \ / \/ /
1839 \ / /\ /
1840 `---X--' `------'</code></pre>
1841 </div></div>
1842 <div class="paragraph"><p>Here, the merge commits <code>O</code> and <code>P</code> contribute extra noise, as they did
1843 not actually contribute a change to <code>file.txt</code>. They only merged a topic
1844 that was based on an older version of <code>file.txt</code>. This is a common
1845 issue in repositories using a workflow where many contributors work in
1846 parallel and merge their topic branches along a single trunk: many
1847 unrelated merges appear in the <code>--full-history</code> results.</p></div>
1848 <div class="paragraph"><p>When using the <code>--simplify-merges</code> option, the commits <code>O</code> and <code>P</code>
1849 disappear from the results. This is because the rewritten second parents
1850 of <code>O</code> and <code>P</code> are reachable from their first parents. Those edges are
1851 removed and then the commits look like single-parent commits that are
1852 TREESAME to their parent. This also happens to the commit <code>N</code>, resulting
1853 in a history view as follows:</p></div>
1854 <div class="listingblock">

1862 </div></div>
1863 <div class="paragraph"><p>In this view, we see all of the important single-parent changes from
1864 <code>A</code>, <code>B</code>, and <code>X</code>. We also see the carefully-resolved merge <code>M</code> and the
1865 not-so-carefully-resolved merge <code>R</code>. This is usually enough information
1866 to determine why the commits <code>A</code> and <code>B</code> "disappeared" from history in
1867 the default view. However, there are a few issues with this approach.</p></div>
1868 <div class="paragraph"><p>The first issue is performance. Unlike any previous option, the
1869 <code>--simplify-merges</code> option requires walking the entire commit history
1870 before returning a single result. This can make the option difficult to
1871 use for very large repositories.</p></div>
1872 <div class="paragraph"><p>The second issue is one of auditing. When many contributors are working
1873 on the same repository, it is important which merge commits introduced
1874 a change into an important branch. The problematic merge <code>R</code> above is
1875 not likely to be the merge commit that was used to merge into an
1876 important branch. Instead, the merge <code>N</code> was used to merge <code>R</code> and <code>X</code>
1877 into the important branch. This commit may have information about why
1878 the change <code>X</code> came to override the changes from <code>A</code> and <code>B</code> in its
1879 commit message.</p></div>

1890 <div class="paragraph"><p>When a merge commit is included by <code>--show-pulls</code>, the merge is
1891 treated as if it "pulled" the change from another branch. When using

1899 the commits <code>X</code> and <code>R</code> into the base branch, respectively. These
1900 merges are the reason the commits <code>A</code> and <code>B</code> do not appear in the
1901 default history.</p></div>
1902 <div class="paragraph"><p>When <code>--show-pulls</code> is paired with <code>--simplify-merges</code>, the

2329 Commit objects record the character encoding used for the log message
2330 in their encoding header; this option can be used to tell the
2331 command to re-code the commit log message in the encoding
2332 preferred by the user. For non plumbing commands this
2333 defaults to UTF-8. Note that if an object claims to be encoded
2334 in <code>X</code> and we are outputting in <code>X</code>, we will output the object
2335 verbatim; this means that invalid sequences in the original
2336 commit may be copied to the output. Likewise, if iconv(3) fails
2337 to convert the commit, we will quietly output the original
2338 object verbatim.

2827 color specification, as described under Values in the
2828 "CONFIGURATION FILE" section of <a href="git-config.html">git-config(1)</a>. By
2829 default, colors are shown only when enabled for log output
2830 (by <code>color.diff</code>, <code>color.ui</code>, or <code>--color</code>, and respecting
2831 the <code>auto</code> settings of the former if we are going to a
2832 terminal). <code>%C(auto,...)</code> is accepted as a historical
2833 synonym for the default (e.g., <code>%C(auto,red)</code>). Specifying
2834 <code>%C(always,...)</code> will show the colors even when color is
2835 not otherwise enabled (though consider just using
2836 <code>--color=always</code> to enable color for the whole output,
2837 including this format and anything else git might color).

3554 <div class="paragraph"><p>The <em>tformat:</em> format works exactly like <em>format:</em>, except that it
3555 provides "terminator" semantics instead of "separator" semantics. In
3556 other words, each commit has the message terminator character (usually a
3557 newline) appended, rather than a separator placed between entries.
3558 This means that the final entry of a single-line format will be properly
3559 terminated with a new line, just as the "oneline" format does.
3560 For example:</p></div>
3561 <div class="listingblock">
3562 <div class="content">
3563 <pre><code>$ git log -2 --pretty=format:%h 4da45bef \
3564 | perl -pe '$_ .= " -- NO NEWLINE\n" unless /\n/'
3565 4da45be
3566 7134973 -- NO NEWLINE
3568 $ git log -2 --pretty=tformat:%h 4da45bef \

3570 4da45be
3571 7134973</code></pre>
3572 </div></div>
3573 <div class="paragraph"><p>In addition, any unrecognized string that has a <code>%</code> in it is interpreted
3574 as if it has <code>tformat:</code> in front of it. For example, these two are
3575 equivalent:</p></div>
