OK, I did $ git-filter-branch --tree-filter 'rm -rf subdir1/ subdir2/ subdir3/' -- --all which looks good, except when I open gitk, I still see "empty" commits that correspond to subdir1/, subdir2/ and subdir3/. Is there anyway to remove those?
A while ago I "complained" that rebase would skip empty commits. You might experiment with that. Alternatively, the following works for me:
git filter-branch --commit-filter 'cmd="git commit-tree"; test `git show --pretty=oneline $GIT_COMMIT|wc -l` = 1 && cmd="skip_commit"; $cmd "$@"' -- --all
This skips all commits which introduce no diff. It will not remove branches or tags which are related only to those subdirs.
I am sure there will be more elegant ways to do that (esp. the test with wc).
