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

NAME         top

       git-fast-export - Git data exporter

SYNOPSIS         top

       git fast-export [options] | git fast-import

DESCRIPTION         top

       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         top

       --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         top

           $ 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         top

       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.
