Keystatus is the only way I know of to accept input while a sleep is running. The read command cannot be used during a countdown sleep loop, as it stops the loop from processing. The fact that is misbehaves although supported is another issue to be reported to GNU.Īs far as testing disks is concerned, the read command is used there to accept user input. Since it returns true on your machine, it is supported on your machine. The purpose of the keystatus command with no operands is to determine whether keystatus is even supported on the platform and version of Windows you are running. The reason you are having this problem is that the keystatus command is not behaving according to GNU Grub specs on your particular hardware.Īs I mentioned earlier, I cannot open an issue with GNU because keystatus works on my machines. Well, you seem to have found a bug in GNU Grub.
