git update hook not receiving any arguments

Question

I read up online that git hook accepts 3 arguments:

the name of the ref being updated,
the old object name stored in the ref,
and the new object name to be stored in the ref.

I am trying to access these arguments but it's empty. What could be wrong here?

#!/bin/bash


echo $@
refname="$1"
oldrev="$2"
newrev="$3"

Based on the comments, I tried adding an echo statement echo "In update hook: Args:$@" and heres the output that I see:

$git push
Counting objects: 6, done.
Delta compression using up to 8 threads.
Compressing objects: 100% (4/4), done.
Writing objects: 100% (6/6), 563 bytes | 0 bytes/s, done.
Total 6 (delta 0), reused 1 (delta 0)

Hooks need to be executable, did you make sure to `chmod +x $yourscriptfile` ? Also, make sure to remove the `.sample` naming from the hook file you are trying to excute. — Bjoern Rennhak, May 29 '18 at 19:45
Also, keep in mind some hooks don't receive arguments via the command line. See eg. https://stackoverflow.com/questions/3762084/git-empty-arguments-in-post-receive-hook — Bjoern Rennhak, May 29 '18 at 19:52
@BjoernRennhak The OP talks about update hook so `$yourscriptfile` is actually `.git/hooks/update`. :-) [Docs say](https://git-scm.com/docs/githooks#update) it really receive 3 parameters at the command line. — phd, May 29 '18 at 20:31
Have you put the script into `git/hooks/update` at the sever repo? Is it executable? Add an echo to verify it's really running, like `echo "In update hook. Args: $@"` — phd, May 29 '18 at 20:34
I did add an echo statement and see that the hook is being triggered but the arguments are empty — iDev, May 29 '18 at 21:31

Thank you Bjoern for the reference link. Based on the link you provided, I am able to retreive the arguments:

Source: git: empty arguments in post-receive hook posted by estani

read oldrev newrev refname
echo "Old revision: $oldrev"
echo "New revision: $newrev"
echo "Reference name: $refname"
