@Scriptor, I am also using AIX 5.3 and ksh.

My script is as below
Code:
#! /bin/ksh
PS1=${HOST:=`uname -n`}"$"; export PS1 HOST;
echo "PS1=$PS1"
echo "HOST=$HOST"
exit

I run this from Xtreme_works server. And the output is
Code:
PS1=Xtreme_works$
HOST=Xtreme_works

I can't understand why is your script giving just $ Smilie

first of all thx for ur help.

by adding ur lines
Code:
echo "PS1=$PS1" echo "HOST=$HOST"

i am getting the o/p but y the dollar sign is coming in o/p
also why echo $PS1 was not working correctly.
Code:
PS1=az91cp01$ 
HOST=az91cp01

Can you please post your script for us to analyze?

Along with the lines where you executed it and the incorrect output.

Thanks Smilie
