Title: "Mastering Environment Variables with Sudo: Keep Full Control and Optimize Your Workflow!"

Introduction: 👋 Hey tech enthusiasts! Are you tired of losing your precious environment variables when using sudo? Fear not, because we've got you covered! In today's blog post, we will unravel the mystery behind this common issue and provide you with easy solutions to keep your environment variables intact, even when using sudo. Let's dive right in!

Understanding the Problem: 🔍 So, why do environment variables vanish into thin air when we add sudo to our commands? When we invoke sudo, it's like starting with a clean slate, as it switches the user to the superuser (root) by default. This includes a different set of environment variables, which leads to the frustration we face when our beloved variables disappear.

Common Issues: 🚫 One of the most frequent issues you might encounter is the inability to bypass certain settings. As described in the given context, the HTTP_PROXY variable is set, but when running a command with sudo, it appears that the proxy setting is not being recognized.

Solutions: 1️⃣ The 'sudo -E' Command: One straightforward solution is to use the '-E' flag in combination with sudo, like so: 'sudo -E wget.' This flag preserves the environment variables, passing them directly to the sudo command. By doing this, you can maintain the HTTP_PROXY variable and enjoy uninterrupted browsing without compromising security.

Example:

sudo -E wget https://example.com

2️⃣ Modifying the sudoers File: Another option is to modify the sudoers file, which gives you more control over environmental preservation. By editing the sudoers file using the 'visudo' command, you can specify which variables should persist when invoking sudo.

Example:

sudo visudo

Add the following line at the end of the file:

Defaults env_keep += "HTTP_PROXY"

Save and exit the file.
