What OS are you running on? In D2, this the definition of system():
int system(string command)
{
if (!command) return std.c.process.system (null);
const commandz = toStringz (command);
invariant status = std.c.process.system (commandz);
if (status == -1) return status;
version (Posix)
return (status & 0x0000ff00) >>> 8;
else
return status;
}
And "(139 & 0x0000ff00) >>> 8" evaluates to 0. I am not sure why it's
not simply returning the raw status-code, though, and only on Posix
systems -- it must be a Posix-ism I'm not familiar with.
