first line should say what shell it is.

for bash type

#/bin/bash

$ with a number gives you number of your argument. $1 is for first argument in the list. you could do echo $1 to print it

#/bin/bash
echo $1 world!

will print the first argument then world!

make sure the script is executable by running $chmod +x ${youfilename}

now you can try:

./${yourscript} hello

and you should see:
hello world!

When I try this: > make sure the script is executable by running $chmod +x ${youfilename}

It complaints that parameter not set :

This is what I have in the script:

#!/bin/ksh
echo $1 world



And I saved it as hello

> Why not I man ..

.. why do we not post the answer to the question about the difference? 'cause its realy tooooooo much to fit in this forum, you can by countless books which explain in detail what the difference is, or simply STFW and you find even more texts than written in books. Which one should be posted her?
Or we (in particular me) could give a (sarcastic) simple answer to a simple question:
 Q: What is the difference between sh and ksh ???
 A: k

Anyway, you initial question have been answerd, haven't it?
