git-fast-export(1) Manual Page

<h2>NAME</h2>
<div class="sectionbody">
<p>git-fast-export -
Git data exporter
</p>
</div>
</div>
<h2 id="_synopsis">SYNOPSIS</h2>
<div class="sectionbody">
<div class="paragraph"><p><em>git fast-export [options]</em> | <em>git fast-import</em></p></div>
</div>
<h2 id="_description">DESCRIPTION</h2>
<div class="sectionbody">
<div class="paragraph"><p>This program dumps the given revisions in a form suitable to be piped
into <em>git fast-import</em>.</p></div>
<div class="paragraph"><p>You can use it as a human-readable bundle replacement (see
<a href="git-bundle.html">git-bundle(1)</a>), or as a kind of an interactive
<em>git filter-branch</em>.</p></div>
</div>
<h2 id="_options">OPTIONS</h2>
<div class="sectionbody">
<div class="dlist"><dl>
<dt class="hdlist1">
--progress=<n>
</dt>
<dd>
<p>
Insert <em>progress</em> statements every <n> objects, to be shown by
<em>git fast-import</em> during import.
</p>
</dd>
<dt class="hdlist1">
--signed-tags=(verbatim|warn|strip|abort)
</dt>
<dd>
<p>
Specify how to handle signed tags. Since any transformation
after the export can change the tag names (which can also happen
when excluding revisions) the signatures will not match.
</p>
<div class="paragraph"><p>When asking to <em>abort</em> (which is the default), this program will die
when encountering a signed tag. With <em>strip</em>, the tags will be made
unsigned, with <em>verbatim</em>, they will be silently exported
and with <em>warn</em>, they will be exported, but you will see a warning.</p></div>
</dd>
<dt class="hdlist1">
--tag-of-filtered-object=(abort|drop|rewrite)
</dt>
<dd>
<p>
Specify how to handle tags whose tagged object is filtered out.
Since revisions and files to export can be limited by path,
tagged objects may be filtered completely.
</p>
<div class="paragraph"><p>When asking to <em>abort</em> (which is the default), this program will die
when encountering such a tag. With <em>drop</em> it will omit such tags from
the output. With <em>rewrite</em>, if the tagged object is a commit, it will
rewrite the tag to tag an ancestor commit (via parent rewriting; see
<a href="git-rev-list.html">git-rev-list(1)</a>)</p></div>
</dd>
<dt class="hdlist1">
-M
</dt>
<dt class="hdlist1">
-C
</dt>
<dd>
<p>
Perform move and/or copy detection, as described in the
<a href="git-diff.html">git-diff(1)</a> manual page, and use it to generate
rename and copy commands in the output dump.
</p>
<div class="paragraph"><p>Note that earlier versions of this command did not complain and
produced incorrect results if you gave these options.</p></div>
</dd>
<dt class="hdlist1">
--export-marks=<file>
</dt>
<dd>
<p>
Dumps the internal marks table to <file> when complete.
Marks are written one per line as <tt>:markid SHA-1</tt>. Only marks
for revisions are dumped; marks for blobs are ignored.
Backends can use this file to validate imports after they
have been completed, or to save the marks table across
incremental runs. As <file> is only opened and truncated
at completion, the same path can also be safely given to
--import-marks.
</p>
</dd>
<dt class="hdlist1">
--import-marks=<file>
</dt>
<dd>
<p>
Before processing any input, load the marks specified in
<file>. The input file must exist, must be readable, and
must use the same format as produced by --export-marks.
</p>
<div class="paragraph"><p>Any commits that have already been marked will not be exported again.
If the backend uses a similar --import-marks file, this allows for
incremental bidirectional exporting of the repository by keeping the
marks the same across runs.</p></div>
</dd>
<dt class="hdlist1">
--fake-missing-tagger
</dt>
<dd>
<p>
Some old repositories have tags without a tagger. The
fast-import protocol was pretty strict about that, and did not
allow that. So fake a tagger to be able to fast-import the
output.
</p>
</dd>
<dt class="hdlist1">
--no-data
</dt>
<dd>
<p>
Skip output of blob objects and instead refer to blobs via
their original SHA-1 hash. This is useful when rewriting the
directory structure or history of a repository without
touching the contents of individual files. Note that the
resulting stream can only be used by a repository which
already contains the necessary objects.
</p>
</dd>
<dt class="hdlist1">
--full-tree
</dt>
<dd>
<p>
This option will cause fast-export to issue a "deleteall"
directive for each commit followed by a full list of all files
in the commit (as opposed to just listing the files which are
different from the commit’s first parent).
</p>
</dd>
<dt class="hdlist1">
[<git-rev-list-args>…]
</dt>
<dd>
<p>
A list of arguments, acceptable to <em>git rev-parse</em> and
<em>git rev-list</em>, that specifies the specific objects and references
to export. For example, <tt>master~10..master</tt> causes the
current master reference to be exported along with all objects
added since its 10th ancestor commit.
</p>
</dd>
</dl></div>
</div>
<h2 id="_examples">EXAMPLES</h2>
<div class="sectionbody">
<div class="listingblock">
<div class="content">
<pre><tt>$ git fast-export --all | (cd /empty/repository && git fast-import)</tt></pre>
</div></div>
<div class="paragraph"><p>This will export the whole repository and import it into the existing
empty repository. Except for reencoding commits that are not in
UTF-8, it would be a one-to-one mirror.</p></div>
<div class="listingblock">
<div class="content">
<pre><tt>$ git fast-export master~5..master |
sed "s|refs/heads/master|refs/heads/other|" |
git fast-import</tt></pre>
</div></div>
<div class="paragraph"><p>This makes a new branch called <em>other</em> from <em>master~5..master</em>
(i.e. if <em>master</em> has linear history, it will take the last 5 commits).</p></div>
<div class="paragraph"><p>Note that this assumes that none of the blobs and commit messages
referenced by that revision range contains the string
<em>refs/heads/master</em>.</p></div>
</div>
<h2 id="_limitations">Limitations</h2>
<div class="sectionbody">
<div class="paragraph"><p>Since <em>git fast-import</em> cannot tag trees, you will not be
able to export the linux-2.6.git repository completely, as it contains
a tag referencing a tree instead of a commit.</p></div>
