6 git-fast-export - Git data exporter
11 'git fast-export [options]' | 'git fast-import'
15 This program dumps the given revisions in a form suitable to be piped
16 into 'git-fast-import'.
18 You can use it as a human readable bundle replacement (see
19 linkgit:git-bundle[1]), or as a kind of an interactive
26 Insert 'progress' statements every <n> objects, to be shown by
27 'git-fast-import' during import.
29 --signed-tags=(verbatim|warn|strip|abort)::
30 Specify how to handle signed tags. Since any transformation
31 after the export can change the tag names (which can also happen
32 when excluding revisions) the signatures will not match.
34 When asking to 'abort' (which is the default), this program will die
35 when encountering a signed tag. With 'strip', the tags will be made
36 unsigned, with 'verbatim', they will be silently exported
37 and with 'warn', they will be exported, but you will see a warning.
41 Perform move and/or copy detection, as described in the
42 linkgit:git-diff[1] manual page, and use it to generate
43 rename and copy commands in the output dump.
45 Note that earlier versions of this command did not complain and
46 produced incorrect results if you gave these options.
48 --export-marks=<file>::
49 Dumps the internal marks table to <file> when complete.
50 Marks are written one per line as `:markid SHA-1`. Only marks
51 for revisions are dumped; marks for blobs are ignored.
52 Backends can use this file to validate imports after they
53 have been completed, or to save the marks table across
54 incremental runs. As <file> is only opened and truncated
55 at completion, the same path can also be safely given to
58 --import-marks=<file>::
59 Before processing any input, load the marks specified in
60 <file>. The input file must exist, must be readable, and
61 must use the same format as produced by \--export-marks.
63 Any commits that have already been marked will not be exported again.
64 If the backend uses a similar \--import-marks file, this allows for
65 incremental bidirectional exporting of the repository by keeping the
66 marks the same across runs.

73 $ git fast-export --all | (cd /empty/repository && git fast-import)
74 -------------------------------------------------------------------
76 This will export the whole repository and import it into the existing
77 empty repository. Except for reencoding commits that are not in
78 UTF-8, it would be a one-to-one mirror.
80 -----------------------------------------------------
81 $ git fast-export master~5..master |
82 sed "s|refs/heads/master|refs/heads/other|" |
84 -----------------------------------------------------
86 This makes a new branch called 'other' from 'master~5..master'
87 (i.e. if 'master' has linear history, it will take the last 5 commits).
89 Note that this assumes that none of the blobs and commit messages
90 referenced by that revision range contains the string
97 Since 'git-fast-import' cannot tag trees, you will not be
98 able to export the linux-2.6.git repository completely, as it contains
99 a tag referencing a tree instead of a commit.
