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.
39 --tag-of-filtered-object=(abort|drop|rewrite)::
40 Specify how to handle tags whose tagged objectis filtered out.
41 Since revisions and files to export can be limited by path,
42 tagged objects may be filtered completely.
44 When asking to 'abort' (which is the default), this program will die
45 when encountering such a tag. With 'drop' it will omit such tags from
46 the output. With 'rewrite', if the tagged object is a commit, it will
47 rewrite the tag to tag an ancestor commit (via parent rewriting; see
48 linkgit:git-rev-list[1])
52 Perform move and/or copy detection, as described in the
53 linkgit:git-diff[1] manual page, and use it to generate
54 rename and copy commands in the output dump.
56 Note that earlier versions of this command did not complain and
57 produced incorrect results if you gave these options.
59 --export-marks=<file>::
60 Dumps the internal marks table to <file> when complete.
61 Marks are written one per line as `:markid SHA-1`. Only marks
62 for revisions are dumped; marks for blobs are ignored.
63 Backends can use this file to validate imports after they
64 have been completed, or to save the marks table across
65 incremental runs. As <file> is only opened and truncated
66 at completion, the same path can also be safely given to
69 --import-marks=<file>::
70 Before processing any input, load the marks specified in
71 <file>. The input file must exist, must be readable, and
72 must use the same format as produced by \--export-marks.
74 Any commits that have already been marked will not be exported again.
75 If the backend uses a similar \--import-marks file, this allows for
76 incremental bidirectional exporting of the repository by keeping the
77 marks the same across runs.
79 --fake-missing-tagger::
80 Some old repositories have tags without a tagger. The
81 fast-import protocol was pretty strict about that, and did not
82 allow that. So fake a tagger to be able to fast-import the
85 [git-rev-list-args...]::
86 A list of arguments, acceptable to 'git-rev-parse' and
87 'git-rev-list', that specifies the specific objects and references
88 to export. For example, `master\~10..master` causes the
89 current master reference to be exported along with all objects
90 added since its 10th ancestor commit.
95 -------------------------------------------------------------------
96 $ git fast-export --all | (cd /empty/repository && git fast-import)
97 -------------------------------------------------------------------
99 This will export the whole repository and import it into the existing
100 empty repository. Except for reencoding commits that are not in
101 UTF-8, it would be a one-to-one mirror.
103 -----------------------------------------------------
104 $ git fast-export master~5..master |
105 sed "s|refs/heads/master|refs/heads/other|" |
107 -----------------------------------------------------
109 This makes a new branch called 'other' from 'master~5..master'
110 (i.e. if 'master' has linear history, it will take the last 5 commits).
112 Note that this assumes that none of the blobs and commit messages
113 referenced by that revision range contains the string
120 Since 'git-fast-import' cannot tag trees, you will not be
121 able to export the linux-2.6.git repository completely, as it contains
122 a tag referencing a tree instead of a commit.
