Shell script

"ls -R|sort|uniq"  should work

Shell script accepts parameters in following format

$1 would be the first command line argument, $2 the second, and so on

$0 is the name of the script or function

If your script has more than 9 params then accept in following way

${12} : 12th param

${18} : 18th param

echo $string | cut -d” ” -f1 
echo $string | cut -d” ” -f2 
echo $string | cut -d” ” -f3

set -x

input_string=$1

if [ -z "$input_string" ] ; then

echo "Please enter a Text along with the script namen"

exit

fi

reversed_string=$(rev $input-string)

if [ "$input_string" -eq "$reverse_string" ] ; then

echo "The String $input_String is a Palindrome"

else

echo "This string is not a palindrome"

fi

ls -R | grep -v "/" | sort | uniq

grep -v "/"  -- is used to filter out directories
