So it would look something like Code: wine drive_c/programme/rockstar\ games/gta\ san\ andreas/gta_sa.exe backspace is not really used in Linux, but here it is used to make the system understand that your next character is special. In this case it is a space. ("\ "). Otherwise, the system would think that you want to provide an argument after the space. Also note that all your backslashes were converted to normal forward slashes. Backslashes only went before the spaces. No quotes are required around the entire string.
