NAME
git-fast-export - Git data exporter
SYNOPSIS
git fast-export [options] | git fast-import
DESCRIPTION
This program dumps the given revisions in a form suitable to
be piped into git fast-import.
You can use it as a human-readable bundle replacement (see
git-bundle(1)), or as a kind of an interactive git
filter-branch.
OPTIONS
--progress=<n>
Insert progress statements every <n> objects, to be
shown by git fast-import during import.
--signed-tags=(verbatim|warn|strip|abort)
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.
When asking to abort (which is the default), this
program will die when encountering a signed tag. With
strip, the tags will be made unsigned, with verbatim,
they will be silently exported and with warn, they will
be exported, but you will see a warning.
--tag-of-filtered-object=(abort|drop|rewrite)
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.
When asking to abort (which is the default), this
program will die when encountering such a tag. With drop
it will omit such tags from the output. With rewrite, if
the tagged object is a commit, it will rewrite the tag
to tag an ancestor commit (via parent rewriting; see
git-rev-list(1))
-M, -C
Perform move and/or copy detection, as described in the
git-diff(1) manual page, and use it to generate rename
and copy commands in the output dump.
Note that earlier versions of this command did not
complain and produced incorrect results if you gave

these options.
--export-marks=<file>
Dumps the internal marks table to <file> when complete.
Marks are written one per line as :markid SHA-1. 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.
--import-marks=<file>
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.
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.
--fake-missing-tagger
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.
--use-done-feature
Start the stream with a feature done stanza, and
terminate it with a done command.
--no-data
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.
--full-tree
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).
[<git-rev-list-args>...]
A list of arguments, acceptable to git rev-parse and git
rev-list, that specifies the specific objects and

references to export. For example, master~10..master
causes the current master reference to be exported along
with all objects added since its 10th ancestor commit.
EXAMPLES
$ git fast-export --all | (cd /empty/repository && git fast-import)
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.
$ git fast-export master~5..master |
sed "s|refs/heads/master|refs/heads/other|" |
git fast-import
This makes a new branch called other from master~5..master
(i.e. if master has linear history, it will take the last 5
commits).
Note that this assumes that none of the blobs and commit
messages referenced by that revision range contains the
string refs/heads/master.
LIMITATIONS
Since git fast-import 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.
