Sending multiple options via "--push-option=" in "git push"

Question

With Git 2.10 a new option came [--push-option=]. When a bare repository is created a post-receive.sample is auto created inside hooks directory, which saying following:

#!/bin/sh
#
# An example hook script to make use of push options.
# The example simply echoes all push options that start with 'echoback='
# and rejects all pushes when the "reject" push option is used.
#
# To enable this hook, rename this file to "pre-receive".

I tried following steps

1. Renaming the file to pre-receive
2. Clone the repository to a local machine
3. tried git push --push-option=echoback=Hello_world

As the sample says it put back the Hello_world in my terminal.

Git Hook Manual says that i could send multiple options via --push-option= which will be available via GIT_PUSH_OPTION_0, GIT_PUSH_OPTION_1,... as the manual suggests.

My Question is How should i pass multiple options ? which could be passed via --push-option=

Tried options:

1. git push --push-option="echoback=Hello echoback=World"
2. git push --push-option="echoback=Hello;echoback=World"
3. git push --push-option="echoback=Hello&echoback=World"
4. git push --push-option="echoback=Hello%echoback=World"
5. git push --push-option="echoback=Hello,echoback=World"

Answer 1

Try the following:

git push --push-option="echoback=Hello" --push-option="echoback=World"

This seperates the --push-options
