Q. How do I write Shell Script to find Greatest of Three Numbers by If-else statement
Ans:
#!/bin/bash echo "enter first number" read first echo "enter second number" read sec echo "enter third number" read third if [ $first -gt $sec ] ; then if [ $first -gt $third ] ; then echo -e " $first is greatest number " else echo -e " $third is greatest number " fi else if [ $sec -gt $third ] ; then echo -e " $sec is greatest number " else echo -e " $third is greatest number " fi fi
