From d208cc353a2860dc9614ba651439713e4ecdf9d3 Mon Sep 17 00:00:00 2001 From: Maria Kustova Date: Tue, 18 Mar 2014 09:59:19 +0400 Subject: [PATCH] qemu-io: Extended "--cmd" description in usage text It's not clear from the usage description that "--cmd" option accepts its argument as a string, so any special symbols have to be quoted from the shell. Updates in usage text: - Specified parameter format for "--cmd" option. - Added an instruction how to get help for "--cmd" option.
