when I run the above script from the command line, i run it as:

OK, good.

notice, there's no where for me to pass whatever argument i need to pass in this command.
Why in the world do you want to do this? The stream editor is not a shell; you aren't changing anything in the script; you are just making it hard to pass an argument to the script and making it EXTREMELY inefficient.

my weak attempts at this were:

Code:
sed -n 1,9p myscript.sh | bash jsmith

and

Code:
sed -n 1,9p myscript.sh | bash $*

You have a working script. You know how to pass parameters to it. What are you trying to do with sed that will be different that what was already working for you without using sed???
