GIT-FAST-EXPORT(1)                Git Manual                GIT-FAST-EXPORT(1)



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).

       --refspec
           Apply the specified refspec to each ref exported. Multiple of them
           can be specified.

       [<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.
