Bash program to check if a number is a palindrome?

To check if a number is a palindrome, we need to reverse the number, then if the original number and the reversed number are the same, it is a palindrome. In Bash, performing the reverse operation is very simple. We need to use the ‘rev’ command to achieve this. Let’s take a look at the program to understand more clearly.

Example

#!/bin/bash
# GNU bash Script
n=12321
rev=$(echo $n | rev)
if [ $n -eq $rev ]; then
   echo "Number is palindrome"
else
   echo "Number is not palindrome"
fi
