I just installed kali on my machine few days ago, and when I wanted to set the proxy using some binary file that could be executed from any other linux distro (like linux mint) but it doesn't work SYSTEM-WIDE, or globally.

I thought that was because the desktop environment since in linux mint, the cinnamon edition, the VPN file worked smoothly without any particular tweaks. So I changed the DE of kali from xfce4 to cinnamon by typing "sudo apt install cinnamon" in the terminal. However, it didn't work.

With some googling, I continued add some details in my /etc/bash.bashrc: export https_proxy="https://127.0.0.1:7890" and hoped it would work at next time I login. Unfortunately, it didn't work again.

What I need: A setting in GUI or files that can apply my VPN to all commands in terminal, other tools in kali. (global proxy setting)
P.S: I install proxychains, but I hate to type it each time with another command.

So how I can do about this? Help me, plz >__<
