How to make hooks in version 1.7.9.5 of git?

Question

In the past, I usually made a post-receive below hooks/. And set permissions 777

This time I helped my friend’s VPS configure GIT but found that there was no post-receive.sample at all. So I created a post-receive myself and tried to enter content and set permissions as usual, but found that it didn't work at all. I tried gg but couldn't find a solution. I would like to ask if anyone with similar experience can give me some advice

hooks/The following file is as shown: (post-receive was created by me)

Answer 1

pre-receive
is executed first when the client pushes, and can be used to reject the client's push.
update
is similar to pre-receive, but will be executed once for each branch.
post-receive
Executed after the client push is completed.

Answer 2

I also asked this question, and someone gave me the answer /q/1010000004382023
It is indeed the case... Create a new document directly to write the content, save it, and then chmod +x post-receive to ensure that it is executable...
