cannot run script

[Richmond Pabilona <rpabilonia@xxxxxxxxxxxxxxxxxxx>]

Hi guys,
   I got this script from this list and named it querykernel.sh but 
everytime i would try to run it using ( $sh querykernel.sh) it gives me 
a command error.

#!/bin/sh
#
# The purpose of this script is to query which kernel
# is currently running on your system...

current kernel

system has been running
