Is myShell.sh a shell or a perl program? If the latter, why isn't the she-bang line the first line? If the former, why the print (instead of echo), or the ls in backquotes?
As for your main program, there should be two new lines after the content-type line, there should not be a space in front of the colon, nor should there be a space after the content type. Furthermore, line 4 seems to be missing a leading / in the path. And print `command` is a bit silly - it's saying "execute command, slurp in its output, then print it". Why not just execute the command? Whatever it outputs will be on your output. Oh, and Line 4 is missing a trailing semi-colon. And I do hope the "Line N :" thingies aren't there in reality - labels cannot contain spaces.
