You couldn't possibly be getting that output based on the code above. For
one, it would never run because your $path variable is not quoted. Second,
when you read from STDIN, you also get the carriage return (\n). Third,
your extension is statically defined, so it must appear somewhere in your
output. And finally, you're not concatenating your string when you put it in
double quotes. Fixing your above code to run produces the following result:

http://someplace.com/images/ . 12345
 . .jpg has been removed

If you post your real code, someone might be able to help you.
