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.
