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|warn-strip|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 silently be made unsigned, with warn-strip they will be made unsigned but a
           warning will be displayed, 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. The file will not be written if no new object has been marked/exported.

       --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.git repository
       completely, as it contains a tag referencing a tree instead of a commit.
