What steps will reproduce the problem? 1. If using a UUID command in a menu then if debug is off you get no outpus 2. For example see http://www.rmprepusb.com/tutorials/xiaopan 3.

What is the expected output? What do you see instead? UUID > nul can be used if no output is required. There is no reason for UUID to take note of debug level

What version of the product are you using? On what operating system?

Please provide any additional information below. For example see http://www.rmprepusb.com/tutorials/xiaopan

Sorry - typo - outpus = output !!

debug 0 uuid (bd) > (md)0x220+1 cat --skip=18 --length=9 (md)0x220+1 | set UUID= echo %UUID%

fails

After using the UUID command, you can use %?% or %?_UUID% To get results debug 0 uuid (bd) && set UUID=%?% echo %UUID%

much better!

uuid () > nul && set UUID=%?%

thanks! please close!

sorry - just tested uuid () > nul && set UUID=%?% and it doesn't work! but uuid () && set UUID=%?% does work - why does it not work if I redirect to nul???

Please try this - something is odd with %?%

title test uuid (bd) && set UUID=%?% echo UUID=%UUID% ?_UUID=%?_UUID% uuid (bd) && set UUID=%?% echo UUID=%UUID% ?_UUID=%?_UUID% pause root

This also does not work (must execute on fresh boot or will appear to work!)

title test uuid (bd) && set UUID=%?% && set var=%_UUID% echo UUID=%UUID% var=%var% ?_UUID=%?_UUID% set UUID=%?% && set var=%?_UUID% echo UUID=%UUID% var=%var% ?_UUID=%?_UUID% pause root

Presumably this is because of order of execution when using && ????

yes!you are right. Should be uuid () && call set UUID =%^?%
