Git Install Script How to enter shell command

Question

This is more of a git related question than openshift.
When I push files to the git server using git, I see that the file permissions of my perl index.cgi file gets changed to 700 in my openshift repo.
Hence every time I do a push, I have to log in to the server using ssh and do a chmod a+x index.cgi in my $OPENSHIFT_REPO_DIR to change it to 755.

I read in the git documentation it is possible to add a hook and I tried updating the post update script in the hooks directory with the following command

exec chmod a+x $OPENSHIFT_DATA_DIR/index.cgi

However that does not seemed to have worked.

Can you please tell me what I am doing wrong ?
How can I ensure I don't have to make the chmod change every time I push files ?

How does one execute shell commands via the git install script (I don't know what is install script, I assume it means the hooks)

based on a below suggestion i thought i would need to add the hook to the server so i tried it but i got an error

$ git add .git/hooks/post-update error: Invalid path '.git/hooks/post-update' error: unable to add .git/hooks/post-update to index

so i tried some options using action hooks by placing a "start" in the local .openshift/action_hooks directory.

The command there ive tried to use was exec chmod a+x register.cgi and even chmod a+x register.cgi

Not much luck. Any inputs. I will be raising this as a separate q against actionhooks.

This is more of a git related question than openshift.

Actually, it is more related to openshift than it is to Git: Git only records 644 and 755 permissions.

But the destination system managing a checkout (and updating a working tree) would set the permission according to the default umask (which could be in your case 077).
Make sure the default umask is 022.

Regarding the hook, check its name ('post-update', no extension) and permission (it must be executable, 755 would be useful)

Bring authority in this case gitweb folder.
