So i have a CLI app built with go , really simple one actually I start the program I get menu option I enter input something happens .
But i want to change it to make it like a tool that runs in background and i enter toolname to access its functionality through terminal anytime . I have never made something like this so i though I could ask community for help

I have never used Tmux so i dont know exactly how it works , but can i use it on server to multi task for monitoring stuff?
or should i just ssh from different terminal?
