Works fine for me. Maybe you'd better do
$ which cp
$ which ls
...and for good measure,
$ /bin/sum.exe
You may find that /bin/sum.exe is *not* what you run when you run
"sum".
FYI, for me, running sum or ./copysum.exe just hangs, it is waiting
for stdin. So I ran the --version option to each, just to see them
do something.
