I wanted to do a demonstration with virsh batch mode, which takes multiple commands all packed into a single argument: $ virsh -c test:///default 'echo a; echo b;' a b but that produced a really long line, so I tried to make it more legible: $ virsh -c test:///default ' echo a; echo b; ' error: unknown command: ' ' Let's be more like the shell, and treat unquoted newline as a command separator just as we do for semicolon. In fact, with that, I can even now mix styles: $ virsh -c test:///default ' echo a; echo b echo c ' a b c Fix the grammer in a nearby comment while at it.
