I think what you mean is this:

Unfortunately if testfile does not exists then Applescript errors.
I believe
this situation started in 10.4, because before then it returned a nul
string. But regardless, you now need to wrap it in a try statement:
try
do shell script "ls ~/testfile"
on error
return ""
end try
or some such gyration. I wish Apple would fix it, but it won't
happen since
I didn't complain about it.
Not to mention the fact that ls's exit status is defined by POSIX.
Take it up with them if you like, but I don't expect you'll get very
far. Incidentally, it would be better to ask the question you
actually wanted to ask, rather than relying on a side effect. In
this case, assuming you're committed to using the shell, that would
be to use test(1).
