Write a shell script to check if the input string is a palindrome

if [ $# -gt 0 ]

then

x=`echo $1 | wc -c`

x=`expr $x - 1`

final=""

while [ $x -gt 0 ]

do

c=`echo $1 | cut -c $x`

x=`expr $x - 1`

final=$final$c

done

fi

if [ $final = $1 ]

then

echo String is palindrome

else

echo The string is not palindrome

fi
