If you just want to see if a host is up..

#!/bin/sh
#

/usr/bin/ping -c 1 192.168.1.2

..would suffice. Substitute /usr/bin/ping -c 1 for whatever command  
and arguments you want to run. Google "beginner bash manual" (note  
that it's for bash--the bourne again shell, not bourne shell--sh),  
but many of the same semantics in bash applying to sh.
