I want to modify a shortcut to use a different CPU affinity, e.g.:

cmd /c "start /affinity 7 path\program"

It works fine, until path or program contains spaces.

Then, quotes surrounding path\program would be needed, nested inside the other quotes.

How can this be achieved?

You don’t need the root quotes in this case. Simply set the shortcut target to:

cmd /c start /affinity 7 "path\program"

I'm stupid :-/ thanks! – Tobias Kienzler Aug 12 '12 at 11:09

You should try to use backslashes as escape character :

cmd /c "start /affinity 7 \"path\program\""

Note that backslashes are only special if they are in front of a quote or a backslash

Update :
Officially, the solution above should work, but in practice it seems it doesn't.

I tried without the backslashes and, although it sounds strange, it works for me (Win XP).

cmd /c "start /affinity 7 "path\program""

that results in > "\"path\program\"" could not be found... – Tobias Kienzler Aug 23 '10 at 13:58
You're right, sorry... Did you try without the backslashes ? I just tried it and it works for me (on XP) : cmd /c "start /affinity 7 "path\program"" – Julien N Aug 23 '10 at 14:26
it does not really work as intended. All consecutive parts of string are just concatenated, may them be quoted or no ("a b"c becomes a bc as one argument), and if you'll add a space to "path\program", you'll see how it fails. – whitequark Aug 23 '10 at 15:37
unfortunately that doesn't work either - for shortcuts. When I use Start->Run... I don't seem to need any quotes at all. Weird. I'm using WinSever2k3. Using a second shortcut to be executed via start ignores the affinity setting, so I guess I have to add program to my path. But thanks for trying, I'll check it on my Win XP at home, too. – Tobias Kienzler Aug 24 '10 at 7:01
