How to Set Proxy Settings on Linux command line or Terminal

Setting a proxy on a Linux system can be useful in a variety of scenarios, such as accessing resources on a network that are restricted to specific IP addresses or protecting your privacy when connecting to the internet. There are several tools and methods available for configuring a proxy on a Linux system, and the specifics will depend on your distribution and the version of Linux you are using.

In this article, we’re going to learn how to set a proxy on Linux’s command line, Ubuntu Desktop GUI, and GNOME3.

On a Linux system, you can configure proxy settings in a few different ways using the command line.

Here are some alternatives:

  • Put environment variables in place: to specify the proxy server for HTTP and HTTPS traffic, respectively, you can set the environment variables HTTP proxy and HTTPS proxy.

Consider this:

export http_proxy=

export https_proxy=

  • Use the proxychains tool: proxychains is a tool that allows you to use a proxy with any command-line program. To use it, you'll need to edit the /etc/proxychains.conf file to specify the proxy server and any other desired settings, and then use the proxychains command to run your desired command. For example:

proxychains curl

  • Use the apt-get tool: If you need to use a proxy to download packages with apt-get, you can specify the proxy by adding a line to the /etc/apt/apt.conf file in the following format:

Acquire::http::Proxy "";

You can also set a separate proxy for HTTPS by adding a similar line with HTTPS instead of HTTP.
