git am /tmp/foo.patch

Merge a git repository in a sub-directory

In weird cases where you have your main repository and want to import a sub-repo into your main one:

cd ./other/repo/
mkdir templates
git mv CRM templates/
git commit -m "moving to templates subdir" -a
git filter-branch --index-filter \
'git ls-files -s | sed "s-CRM/-templates/CRM/-" | GIT_INDEX_FILE=$GIT_INDEX_FILE.new \
git update-index --index-info &&
mv $GIT_INDEX_FILE.new $GIT_INDEX_FILE' HEAD

Then move back to the root of your main git repository and pull:

cd ../../
git pull

The delete the .git in "other/repo/.git".
