You're right. It works on my system too - I just passed it to another
function which I assumed worked.

So the problem is actually with using system under Linux. Example:
DOS: system("cd c:\\",2) -- current_dir() returns "c:\" after
Linux: system("cd /",2) -- but current_dir() doesn't return "/" after
