I've also tried to make this a plain bash script (w/o the function or
if statements and am failing at the same place). The issue seems to be
with the quoting in the filter-branch | ls-files bit. Also, the end
goal here is to be able to move a directory from one repo and keep the
history. While this works if I do it at the command line, it's just
too many steps (is tedious). Also, if there's a way to do the same
thing with multiple directories in one shot, (or make this work with
something like: cookbooks/{a,b,c} # as a parameter) that'd be perfect.

  reapdir = "!f() { \
    if [ -d "$1" ] ; then \
      git filter-branch --prune-empty --subdirectory-filter "$1" -- --all && \
      git gc --aggressive && \
      git prune && \
      git filter-branch -f --prune-empty --index-filter '\
        git ls-files -s \
          | sed \"s-\\t-&$1-\" \
          | GIT_INDEX_FILE=$GIT_INDEX_FILE.new git update-index
--index-info && \
            mv $GIT_INDEX_FILE.new $GIT_INDEX_FILE'; \
    else \
      echo "No directory $1"; \
    fi; }; \
  f"

```

BTW, just trying to get filter-branch to interpret the bash script
string correctly now and it still isn't working:

git filter-branch -f --prune-empty --index-filter "\
  git ls-files -s | \
  sed \"s-\\t\\\"*-&${1}-\" | \
  GIT_INDEX_FILE=\$GIT_INDEX_FILE.new \
  git update-index --index-info && \
    mv \$GIT_INDEX_FILE.new \$GIT_INDEX_FILE \
" HEAD

 I'm guessing bash is grabbing my actual bash shell is grabbing the
GIT_INDEX_FILE declaration for itself. If this is the case, I'm not
sure how to stop it - tried var\=\$var.new and that passes the '\='
which totally messes things up.

FWIW, I (finally) found two projects that like they'll do what I want:
git-splits and git_filter
The later was lacking in documentation and after the build I couldn't
figure it out at a glance and I think git-splits will DWIW.

I think I finally figured out how I want to do this:

git remote add temp ../<temp repo>/
git fetch temp
git merge -s ours --no-commit temp/master
git read-tree --prefix=<wanted directory> -u temp/master:<wanted directory>
git commit -m "foo"

However, when I do this, I've got all of the commits from the original
(temp) repo. How do I prune these out? None of the files show up, but
I do see reference to them in: git log --stat. And nothing I do with
gc or prune seem to have any affect.

Did you try git subtree
(https://github.com/git/git/blob/master/contrib/subtree/git-subtree.txt)?

```

Yeah, it looked like it left the repo in the same state as
subdirectory-filter and the merge failed. But I'll try it again when I
get to work.
