checking if a string is a palindrome

Question

I am trying to check if a string is a palindrome in bash. Here is what I came up with:

#!/bin/bash
read -p \"Enter a string: \" string
if [[ $string|rev ==         


        

Answer 1

Use $(command substitution):

#!/bin/bash
read -p "Enter a string: " string
if [[ "$(echo "$string" | rev)" == "$string" ]]; then
    echo "Palindrome"
fi
