A shell script is not compiled and linked so we can't have an exec.
version of it as we have in a programming lang. . Is there a way that
after writing a (bourne ) shell script we make it executable and just
give the executable version to somebody (making a script executable by
chmod does not make a seperate exec. version and to give somebody you
have to give the script itself).

(1) For security (you don't want them having the source to your script)

    Easy enough.  Make a C program which has the script text as data.
    Use Popen() to exec a copy of the shell, with an input pipe to
    it.  Stuff the script text into the pipe and watch what comes out.
    Or write stuff to a temp file, fork(), exec(/bin/sh,tmpfile),
    then when /bin/sh terminates, erase the file.

(2) For completeness (in case they don't have /bin/sh)

    who doesn't have at least /bin/sh?????

I'd guess you're more concerned about (1) than (2).
