How to type it ?
If you are on windows, you can type it in a file that will run the command when you run it.
To do so, open Notepad and type the command there. Then go to Save as... and in the dropdown select All files(*.*) and save it as "runminer.bat" (without the quotation marks, of course) at the folder where your miner is. You can write anything in place of runminer but make sure it ends in .bat .
After that, every time you run the .bat file, a command terminal will open and automatically execute the command.
