<h2 id="_description">DESCRIPTION</h2>
<div class="sectionbody">
<div class="paragraph"><p>Shows one or more objects (blobs, trees, tags and commits).</p></div>
<div class="paragraph"><p>For commits it shows the log message and textual diff. It also
presents the merge commit in a special format as produced by
<em>git diff-tree --cc</em>.</p></div>
<div class="paragraph"><p>For tags, it shows the tag message and the referenced objects.</p></div>
<div class="paragraph"><p>For trees, it shows the names (equivalent to <em>git ls-tree</em>
with --name-only).</p></div>
<div class="paragraph"><p>For plain blobs, it shows the plain contents.</p></div>
<div class="paragraph"><p>The command takes options applicable to the <em>git diff-tree</em> command to
control how the changes the commit introduces are shown.</p></div>
<div class="paragraph"><p>This manual page describes only the most frequently used options.</p></div>
</div>
<h2 id="_options">OPTIONS</h2>
<div class="sectionbody">
<div class="dlist"><dl>
<dt class="hdlist1">
<object>…
</dt>
<dd>
<p>
The names of objects to show.
For a more complete list of ways to spell object names, see
"SPECIFYING REVISIONS" section in <a href="gitrevisions.html">gitrevisions(7)</a>.
</p>
</dd>
<dt class="hdlist1">
--pretty[=<format>]
</dt>
<dt class="hdlist1">
--format=<format>
</dt>
<dd>
<p>
Pretty-print the contents of the commit logs in a given format,
where <em><format></em> can be one of <em>oneline</em>, <em>short</em>, <em>medium</em>,
<em>full</em>, <em>fuller</em>, <em>email</em>, <em>raw</em> and <em>format:<string></em>. See
the "PRETTY FORMATS" section for some additional details for each
format. When omitted, the format defaults to <em>medium</em>.
</p>
<div class="paragraph"><p>Note: you can specify the default pretty format in the repository
configuration (see <a href="git-config.html">git-config(1)</a>).</p></div>
</dd>
<dt class="hdlist1">
--abbrev-commit
</dt>
<dd>
<p>
Instead of showing the full 40-byte hexadecimal commit object
name, show only a partial prefix. Non default number of
digits can be specified with "--abbrev=<n>" (which also modifies
diff output, if it is displayed).
</p>
<div class="paragraph"><p>This should make "--pretty=oneline" a whole lot more readable for
people using 80-column terminals.</p></div>
</dd>
<dt class="hdlist1">
--no-abbrev-commit
</dt>
<dd>
<p>
Show the full 40-byte hexadecimal commit object name. This negates
<tt>--abbrev-commit</tt> and those options which imply it such as
"--oneline". It also overrides the <em>log.abbrevCommit</em> variable.
</p>
</dd>
<dt class="hdlist1">
--oneline
</dt>
<dd>
<p>
This is a shorthand for "--pretty=oneline --abbrev-commit"
used together.
</p>
</dd>
<dt class="hdlist1">
--encoding[=<encoding>]
</dt>
<dd>
<p>
The commit objects record the encoding used for the log message
in their encoding header; this option can be used to tell the
command to re-code the commit log message in the encoding
preferred by the user. For non plumbing commands this
defaults to UTF-8.
</p>
</dd>
<dt class="hdlist1">
--notes[=<ref>]
</dt>
<dd>
<p>
Show the notes (see <a href="git-notes.html">git-notes(1)</a>) that annotate the
commit, when showing the commit log message. This is the default
for <tt>git log</tt>, <tt>git show</tt> and <tt>git whatchanged</tt> commands when
there is no <tt>--pretty</tt>, <tt>--format</tt> nor <tt>--oneline</tt> option given
on the command line.
</p>
<div class="paragraph"><p>By default, the notes shown are from the notes refs listed in the
<em>core.notesRef</em> and <em>notes.displayRef</em> variables (or corresponding
environment overrides). See <a href="git-config.html">git-config(1)</a> for more details.</p></div>
<div class="paragraph"><p>With an optional <em><ref></em> argument, show this notes ref instead of the
default notes ref(s). The ref is taken to be in <tt>refs/notes/</tt> if it
is not qualified.</p></div>
<div class="paragraph"><p>Multiple --notes options can be combined to control which notes are
being displayed. Examples: "--notes=foo" will show only notes from
"refs/notes/foo"; "--notes=foo --notes" will show both notes from
"refs/notes/foo" and from the default notes ref(s).</p></div>
</dd>
<dt class="hdlist1">
--no-notes
</dt>
<dd>
<p>
Do not show notes. This negates the above <tt>--notes</tt> option, by
resetting the list of notes refs from which notes are shown.
Options are parsed in the order given on the command line, so e.g.
"--notes --notes=foo --no-notes --notes=bar" will only show notes
from "refs/notes/bar".
</p>
</dd>
<dt class="hdlist1">
--show-notes[=<ref>]
</dt>
<dt class="hdlist1">
--[no-]standard-notes
</dt>
<dd>
<p>
These options are deprecated. Use the above --notes/--no-notes
options instead.
</p>
</dd>
</dl></div>
</div>
<h2 id="_pretty_formats">PRETTY FORMATS</h2>
<div class="sectionbody">
<div class="paragraph"><p>If the commit is a merge, and if the pretty-format
is not <em>oneline</em>, <em>email</em> or <em>raw</em>, an additional line is
inserted before the <em>Author:</em> line. This line begins with
"Merge: " and the sha1s of ancestral commits are printed,
separated by spaces. Note that the listed commits may not
necessarily be the list of the <strong>direct</strong> parent commits if you
have limited your view of history: for example, if you are
only interested in changes related to a certain directory or
file.</p></div>
<div class="paragraph"><p>There are several built-in formats, and you can define
additional formats by setting a pretty.<name>
config option to either another format name, or a
<em>format:</em> string, as described below (see
<a href="git-config.html">git-config(1)</a>). Here are the details of the
built-in formats:</p></div>

<div class="paragraph"><p>The <em>tformat:</em> format works exactly like <em>format:</em>, except that it
provides "terminator" semantics instead of "separator" semantics. In
other words, each commit has the message terminator character (usually a
newline) appended, rather than a separator placed between entries.
This means that the final entry of a single-line format will be properly
terminated with a new line, just as the "oneline" format does.
For example:</p></div>
<div class="listingblock">
<div class="content">
<pre><tt>$ git log -2 --pretty=format:%h 4da45bef \

$ git log -2 --pretty=tformat:%h 4da45bef \
| perl -pe '$_ .= " -- NO NEWLINE\n" unless /\n/'
4da45be
7134973</tt></pre>
</div></div>
<div class="paragraph"><p>In addition, any unrecognized string that has a <tt>%</tt> in it is interpreted
as if it has <tt>tformat:</tt> in front of it. For example, these two are
equivalent:</p></div>
<div class="listingblock">
<div class="content">
<pre><tt>$ git log -2 --pretty=tformat:%h 4da45bef

<p>
The pathnames recorded in the index and in the tree objects
are treated as uninterpreted sequences of non-NUL bytes.
What readdir(2) returns are what are recorded and compared
with the data git keeps track of, which in turn are expected
to be what lstat(2) and creat(2) accepts. There is no such
thing as pathname encoding translation.

The contents of the blob objects are uninterpreted sequences

</li>
</ul></div>
<div class="paragraph"><p>Although we encourage that the commit log messages are encoded
in UTF-8, both the core and git Porcelain are designed not to
force UTF-8 on projects. If all participants of a particular

does not forbid it. However, there are a few things to keep in
mind.</p></div>

<li>
<p>
<em>git commit</em> and <em>git commit-tree</em> issues
a warning if the commit log message given to it does not look
like a valid UTF-8 string, unless you explicitly say your
project uses a legacy encoding. The way to say this is to
have i18n.commitencoding in <tt>.git/config</tt> file, like this:
</p>
<div class="listingblock">
<div class="content">
<pre><tt>[i18n]
commitencoding = ISO-8859-1</tt></pre>

<div class="paragraph"><p>Commit objects created with the above setting record the value
of <tt>i18n.commitencoding</tt> in its <tt>encoding</tt> header. This is to
help other people who look at them later. Lack of this header

</li>
<li>
<p>
<em>git log</em>, <em>git show</em>, <em>git blame</em> and friends look at the
<tt>encoding</tt> header of a commit object, and try to re-code the
log message into UTF-8 unless otherwise specified. You can
specify the desired output encoding with
<tt>i18n.logoutputencoding</tt> in <tt>.git/config</tt> file, like this:
</p>
<div class="listingblock">
<div class="content">
<pre><tt>[i18n]
logoutputencoding = ISO-8859-1</tt></pre>
</div></div>
<div class="paragraph"><p>If you do not have this configuration variable, the value of
<tt>i18n.commitencoding</tt> is used instead.</p></div>
</li>
</ol></div>
<div class="paragraph"><p>Note that we deliberately chose not to re-code the commit log
message when a commit is made to force UTF-8 at the commit
object level, because re-coding to UTF-8 is not necessarily a
reversible operation.</p></div>
