For the first time, I try to collaborate with my colleagues on git. Because we are afraid of ruining the master branch, I add the pre-receive hook on the remote server. At first I was trying to use the /dev/tty as suggested in

https://dev.ghost.org/prevent-master-push/

, however I realize for the remote server the ssh does not provide the prompt. I decide that the master can only be upated if the change has been submitted to stable_release branch.

2017.03.10 update:
(1) deleting stable_release and master branch is not allowed.
(2) new branch can be added only if it ends with _dev.

The code is the following:

# The "post-receive" script is run after receive-pack has accepted a pack
# and the repository has been updated.  It is passed arguments in through
# stdin in the form
#  <oldrev> <newrev> <refname>
# For example:
#  aa453216d1b3e49e7f6f98441fa56946ddcd6a20 68f7abf4e6f922807889f52bc043ecd31b79f814 refs/heads/master
#
# see contrib/hooks/ for a sample, or uncomment the next line and
# rename the file to "post-receive".

#. /usr/share/git-core/contrib/hooks/post-receive-email
while read oldrev newrev refname
do
  # not push
