DESCRIPTION
-----------
--commit-filter <command>::
This is the filter for performing the commit.
If this filter is specified, it will be called instead of the
- `git-commit-tree` command, with arguments of the form
+ 'git-commit-tree' command, with arguments of the form
"<TREE_ID> [-p <PARENT_COMMIT_ID>]..." and the log message on
stdin. The commit id is expected on stdout.
+
You can use the 'map' convenience function in this filter, and other
convenience functions, too. For example, calling 'skip_commit "$@"'
will leave out the current commit (but not its changes! If you want
-that, use `git-rebase` instead).

--tag-name-filter <command>::
This is the filter for rewriting tag names. When passed,

+ 'git-filter-branch' refuses to start with an existing temporary
directory or when there are already refs starting with
'refs/original/', unless forced.
-<rev-list-options>::
- When options are given after the new branch name, they will
- be passed to `git-rev-list`. Only commits in the resulting
- output will be filtered, although the filtered commits can still
- reference parents which are outside of that set.
+<rev-list options>...::
+ Arguments for 'git-rev-list'. All positive refs included by
+ these options are rewritten. You may also specify options
+ such as '--all', but you must use '--' to separate them from
+ the 'git-filter-branch' options.
Examples
A significantly faster version:
--------------------------------------------------------------------------
-git filter-branch --index-filter 'git update-index --remove filename' HEAD
+git filter-branch --index-filter 'git rm --cached filename' HEAD
--------------------------------------------------------------------------
Now, you will get the rewritten history saved in HEAD.
+To rewrite the repository to look as if `foodir/` had been its project
+root, and discard all other history:
+
+-------------------------------------------------------
+git filter-branch --subdirectory-filter foodir -- --all
+-------------------------------------------------------
+
+Thus you can, e.g., turn a library subdirectory into a repository of
+its own. Note the `\--` that separates 'filter-branch' options from
+revision options, and the `\--all` to rewrite all branches and tags.

To set a commit (which typically is at the tip of another
history) to be the parent of the current initial commit, in
order to paste the other history behind the current history:
as their parents instead of the merge commit.
You can rewrite the commit log messages using `--msg-filter`. For
-example, `git-svn-id` strings in a repository created by `git-svn` can

To restrict rewriting to only part of the history, specify a revision
range in addition to the new branch name. The new branch name will
-point to the top-most revision that a `git-rev-list` of this range

will print.
*NOTE* the changes introduced by the commits, and which are not reverted
by subsequent commits, will still be in the rewritten branch. If you want
to throw out _changes_ together with the commits, you should use the
-interactive mode of `git-rebase`.
