git‐cvsexportcommit − Export a single commit to a CVS

git cvsexportcommit [−h] [−u] [−v] [−c] [−P] [−p] [−a] [−d cvsroot]
        [−w cvsworkdir] [−W] [−f] [−m msgprefix] [PARENTCOMMIT] COMMITID

Exports a commit from Git to a CVS checkout, making it
easier to merge patches from a Git repository into a CVS

Specify the name of a CVS checkout using the −w switch or
execute it from the root of the CVS working copy. In the
latter case GIT_DIR must be defined. See examples below.

It does its best to do the safe thing, it will check that
the files are unchanged and up to date in the CVS checkout,
and it will not autocommit by default.

Supports file additions, removals, and commits that affect
binary files.

If the commit is a merge commit, you must tell git
cvsexportcommit what parent the changeset should be done

     Commit automatically if the patch applied cleanly. It
     will not commit if any hunks fail to apply or there
     were other problems.

     Be pedantic (paranoid) when applying patches. Invokes
     patch with −−fuzz=0

     Add authorship information. Adds Author line, and
     Committer (if different from Author) to the message.

     Set an alternative CVSROOT to use. This corresponds to
     the CVS −d parameter. Usually users will not want to
     set this, except if using CVS in an asymmetric fashion.

     Force the merge even if the files are not up to date.


     Force the parent commit, even if it is not a direct

     Prepend the commit message with the provided prefix.
     Useful for patch series and the like.

     Update affected files from CVS repository before
     attempting export.

     Reverse CVS keyword expansion (e.g. $Revision:$
     becomes $Revision$) in working CVS checkout before
     applying patch.

     Specify the location of the CVS checkout to use for the
     export. This option does not require GIT_DIR to be set
     before execution if the current directory is within a
     Git repository. The default is the value of

     Tell cvsexportcommit that the current working directory
     is not only a Git checkout, but also the CVS checkout.
     Therefore, Git will reset the working directory to the
     parent commit before proceeding.

     Merge one patch into CVS

          $ export GIT_DIR=~/project/.git
          $ cd ~/project_cvs_checkout
          $ git cvsexportcommit −v <commit−sha1>
          $ cvs commit −F .msg <files>

     Merge one patch into CVS (−c and −w options). The
working directory is within the Git Repo

                  $ git cvsexportcommit −v −c −w ~/project_cvs_checkout <commit−sha1>


     Merge pending patches into CVS automatically — only if
you really know what you are doing

          $ export GIT_DIR=~/project/.git
          $ cd ~/project_cvs_checkout
          $ git cherry cvshead myhead | sed −n 's/^+ //p' | xargs −l1 git cvsexportcommit −c −p −v
