如何将新的 git 挂钩安装到所有现有（克隆）存储库？

Question

I have ~50 repositories on my machine. I would like to install newly created git hook to all of them.

I've already created .git-templates folder and put hooks there, then git config --global init.templatedir ~/.git-templates - it works for new repositories but what about existing ones?

Answer 1

I you use a recent version of git (>= 2.9), then I would recommend using the core.hooksPath variable.

Then you can create a separate directory where you put all your hooks, eg /var/myhooks , then

git config --global core.hooksPath /var/myhooks

would make this directory the default hooks directory for all your repositories at once. As a side effect, all hooks under .git/hooks in each repository will be ignored. But inside a specific repository, you could then override this again with its own hooks directory:

git config core.hooksPath .git/hooks

Answer 2

Just do it. Find all the repositories and copy the hooks. Here's a sample (this might find more than you think, it's why the actual copy gets echoed not executed, don't just c&p the echoed commands if you might have ' 's in your pathnames):

find ~ -name HEAD -execdir test -f config -a -d objects -a -d refs \; \
        -execdir mkdir -p hooks \; \
        -printf "cp -a ~/.git-templates/hooks '%h'/hooks\\n"
