Write a Shell program to find the smallest digits of a number?

Answer 1

You can create a Shell script to find the smallest digit of a number by iterating through its digits. Here's a simple example:

#!/bin/bash
read -p "Enter a number: " number
smallest=9

for (( i=0; i<${#number}; i++ )); do
    digit=${number:$i:1}
    if (( digit < smallest )); then
        smallest=$digit
    fi
done

echo "The smallest digit is: $smallest"

This script prompts the user for a number, checks each digit, and prints the smallest one.
