Hi namishtiwari and zaxxon and all,
I really appreciate your patience...

Thank You ur code worked.

but it was just a sample code given.my actuall program is NOT working.
i wanted/used the same concept in one of my module of a Huge program.

here is my actual code,i wonder y it's not working.
the concept is same as our sample code.

#!/bin/sh
egrep '(Latch Hit)...' /oracle/zaheer/parts/part4 | awk '{print "Latch Hit "$9 " %"}'
set value=99
if [ $9 -lt $value ] ;
then
echo "Your latch it is $9 It is very is Low"
else
echo "You Have $9 latch hit which is Very Good"
fi

output:
$ ./latch.sh
Latch Hit 100.00 %
Your latch it is It is very is Low
Again wrong loop,again witout $9 value. YYYYY?i dont know...IM GOING MAD.

Please help me here....
