#!/bin/ksh

i=1
tag=0

print -n "Enter a String:"
read str
len=`echo $str | wc -c`
if [[ $len -eq 1 ]]
then
print "Enter a valid string"
exit 2;
fi

let len=len-1
let halflen=len/2;

while [[ $i -le $halflen ]]
do

c2=`echo $str | cut -c $len`

if [[ $c1 != $c2 ]]
then
tag=1;
fi

len=`expr $len - 1`
done

if [ $tag -eq 0 ]
then
echo "String is Palindrome"
else
echo "String is not Palindrome"
fi
