Concat Strings in a batch file

Question

I am generating a Guid in a batch file, then I need to wrap that Guid in curly braces. How do I do that?

for /f %%i in ('"C:\Program Files\Microsoft SDKs\Windows\v7.1\Bin\uuidgen.exe"') do set guid=%%i

ECHO %guid%
pause

set guid = "{"%guid%"}"
ECHO %guid%

My solution doesnt seem to work. Any ideas?

set guid={%guid%}

As simple as that. Note that you shouldn't have spaces around the = (because your variable name would end in a space and its value would start with one) and quotes are included verbatim in the value unless you quote the complete argument to set by using set "foo=bar" but that isn't necessary here.

You can do it directly in your for loop too, by the way: set guid={%%i}.
