GTU OS Program - 8

8. Write a shell script to read n numbers as command arguments and sort them in descending order.

Complete code of the program

read -p "Enter the number of values you want to sort "  n

for((i=0; i<$n; i++))
do
        read -p "Enter value of arr[$i]: " arr[$i]
done
#sorting code
for((i=0; i<$n; i++))
do
        for((j=0; j<n-i-1; j++))
        do
                if [ ${arr[j]} -lt ${arr[$((j+1))]} ]
                then
                        #swapping
                        temp=${arr[j]}
                        arr[$j]=${arr[$((j+1))]}
                        arr[$((j+1))]=$temp
                fi
        done
done

echo "Numbers sorted in descending order as"
echo ${arr[*]}

Interpreting the sort.sh file and executing it in terminal

tkanu025@hp:~/lab_solutions$ chmod +x sort.sh
tkanu025@hp:~/lab_solutions$ ./sort.sh
