Java external command : not found, createProcess errno=2

Question

I try

ProcessBuilder().command("C:\\Windows\\System32\\sc.exe query power");

or

ProcessBuilder().command("c:/windows/system32/sc.exe query power");

or

ProcessBuilder().command("c:/windows/system32/sc query power");

I always get the same error ...

Please re-read carefully the Javadoc (especially the examples) for `ProcessBuilder`. — Jim Garrison, Apr 11 '19 at 15:55
That isn't valid Java code. You're missing the very important `new` keyword to make it valid. — Andreas, Apr 11 '19 at 16:05

You should submit each argument for sc.exe separately to ProcessBuilder to avoid issues with argument escaping or quoting. Right now you have the whole command as a single String expression, this cause the problem.

Since C:\Windows\System32 directory should be in the system PATH it should enough to do.

ProcessBuilder pb = new ProcessBuilder("sc.exe", "query", "power");
Process p = pb.start();
int result = p.waitFor();

ultimately, I used `new ProcessBuilder("sc", "query", "power");` so yes it's in the path and yes I think it's the best way to do, because "cmd arg1 arg2 etc.." is interpreted as a single exe name (so with spaces) by the jvm thanks ! – Minstrel Apr 11 '19 at 16:18
