How to keep environment variables when using sudo

Question

When I use any command with sudo the environment variables are not there. For example after setting HTTP_PROXY the command wget works fine without sudo

Answer 1

You can also combine the two env_keep statements in Ahmed Aswani's answer into a single statement like this:

Defaults env_keep += "http_proxy https_proxy"

You should also consider specifying env_keep for only a single command like this:

Defaults!/bin/[your_command] env_keep += "http_proxy https_proxy"
