The first of two tools we will build allows the user to add, list, and remove paths for the backup daemon tool (which we will write later). You could expose a web interface, or even use the binding packages for desktop user interface integration, but we are going to keep things simple and build ourselves a command-line tool.
Create a new folder called cmds
inside the backup
folder and create another backup
folder inside that.
Inside our new backup
folder, add the following code to main.go
