Using multiple post-receive hooks

The most commonly used post-receive hook is probably one that sends mail about incoming pushes. Git ships one that works reasonably well, and there's also the git-multimail hook.

But what if you want to do more than one thing in the post-receive hook? You cannot easily run more than one hook, as the hook needs to consume all input on stdin. So the most common approach is to hack something in the hook, making upgrading git more painful as this needs to be forward-ported all the time.

So instead, please use pee from the moreutils project to multiplex the input the hook gets and you can use as many hooks as you want

The default hook post-receive hook:

1
2

#!/bin/sh
. /usr/share/doc/git-core/contrib/hooks/post-receive-email

A hook that runs several more hooks (in this case: submitting the job to a Jenkins CI server and scheduling a push to a mirror repository):

1
2
3
4

#!/bin/sh
/usr/bin/pee /usr/share/doc/git/contrib/hooks/post-receive-email \
             /srv/gitroot/custom-hooks/jenkins \
             /srv/gitroot/custom-hooks/schedule-sync
