It did. But only in the new process. Environment changes don't affect
other processes. In DOS, if a .bat changed the current dir, it also
changed it for the shell. In Linux, each process keeps it's current dir
and can only change its own.

That's because the current path isn't in your PATH environment variable.
Add it like this: PATH=$PATH:., or rather call linux with ./linux. Having
the current directory in PATH is a security problem.
