1git-fast-export(1) 2================== 3 4NAME 5---- 6git-fast-export - Git data exporter 7 8 9SYNOPSIS 10-------- 11'git fast-export [options]' | 'git fast-import' 12 13DESCRIPTION 14----------- 15This program dumps the given revisions in a form suitable to be piped 16into 'git-fast-import'. 17 18You can use it as a human readable bundle replacement (see 19linkgit:git-bundle[1]), or as a kind of an interactive 20'git-filter-branch'. 21 22 23OPTIONS 24------- 25--progress=<n>:: 26 Insert 'progress' statements every <n> objects, to be shown by 27 'git-fast-import' during import. 28 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. 33+ 34When asking to 'abort' (which is the default), this program will die 35when encountering a signed tag. With 'strip', the tags will be made 36unsigned, with 'verbatim', they will be silently exported 37and with 'warn', they will be exported, but you will see a warning. 38 39--export-marks=<file>:: 40 Dumps the internal marks table to <file> when complete. 41 Marks are written one per line as `:markid SHA-1`. Only marks 42 for revisions are dumped; marks for blobs are ignored. 43 Backends can use this file to validate imports after they 44 have been completed, or to save the marks table across 45 incremental runs. As <file> is only opened and truncated 46 at completion, the same path can also be safely given to 47 \--import-marks. 48 49--import-marks=<file>:: 50 Before processing any input, load the marks specified in 51 <file>. The input file must exist, must be readable, and 52 must use the same format as produced by \--export-marks. 53+ 54Any commits that have already been marked will not be exported again. 55If the backend uses a similar \--import-marks file, this allows for 56incremental bidirectional exporting of the repository by keeping the 57marks the same across runs. 58 59 60EXAMPLES 61-------- 62 63------------------------------------------------------------------- 64$ git fast-export --all | (cd /empty/repository && git fast-import) 65------------------------------------------------------------------- 66 67This will export the whole repository and import it into the existing 68empty repository. Except for reencoding commits that are not in 69UTF-8, it would be a one-to-one mirror. 70 71----------------------------------------------------- 72$ git fast-export master~5..master | 73 sed "s|refs/heads/master|refs/heads/other|" | 74 git fast-import 75----------------------------------------------------- 76 77This makes a new branch called 'other' from 'master~5..master' 78(i.e. if 'master' has linear history, it will take the last 5 commits). 79 80Note that this assumes that none of the blobs and commit messages 81referenced by that revision range contains the string 82'refs/heads/master'. 83 84 85Limitations 86----------- 87 88Since 'git-fast-import' cannot tag trees, you will not be 89able to export the linux-2.6.git repository completely, as it contains 90a tag referencing a tree instead of a commit. 91 92 93Author 94------ 95Written by Johannes E.
