[Question] How to get information in post-receive git hook

[UziTech]

How can I get the information provided to stdin in the git post-receive hook?

I've tried

read var
echo $var

and it returns nothing

post-receive hook doesn't get anything from stdin. See git documentation on how to use it: https://git-scm.com/docs/githooks

post-receive

This hook is invoked by git-receive-pack on the remote repository, which happens when a git push is done on a local repository. It executes on the remote repository once after all the refs have been updated.

This hook executes once for the receive operation. It takes no arguments, but gets the same information as the pre-receive hook does on its standard input.

pre-receive

This hook executes once for the receive operation. It takes no arguments, but for each ref to be updated it receives on standard input a line of the format:

<old-value> SP <new-value> SP <ref-name> LF
