result:
Object "ute" is unknown, try "ip help".

That is the first two bytes are lost

Adding two spaces works:
#import std.process
void main() {
    execvp("ip", "  route");
}

Thanks.

Definitely a bug, but likely one that will not be fixed.  std.process has  
been rewritten, and the result is waiting for a change to the Windows C  
runtime (dmc) for supporting pipes.

However, you are on Linux, so you can probably use the updated std.process

see here:

https://github.com/kyllingstad/phobos/tree/new-std-process

You will likely have to do some git cloning to get these into the latest  
phobos.
