Network Proxy: Apply System-Wide

In several latest version of Ubuntu, we have Network Proxy Preferences menu. In this article, I want to show the effect of Apply System-Wide option. One of this effect is when we work in Terminal.

# Before applying system-wide proxy, try echoing proxy in Terminal and it will show nothing

echo $http_proxy

# After choosing this option, close Terminal. Then try echoing again and you will get message like this

http://username:password@proxy_ip_address:port/

It means you have applied proxy system-wide option. Enjoy!
