Shell Programs
Biggest among two numbers


AIM:

            To write a shell script program to find the biggest among given two numbers

ALGORITHM:

            Step 1: Start the program
           
            Step 2: Read the two numbers a and b

            Step 3: If ‘a’ is greater than ‘b’ go to step4.

            Step 4: If ‘b’ is greater than ‘a’ go to step5.

            Step 5: Print A is greater.

            Step 6 : Print B is greater.

            Step 7 : Stop the program

 if condition
then
command1
...
...
fi
 
SCRIPT:
            echo "Enter the first number\n”
read a
echo "Enter the second number\n "
read b
if [$a –gt $b]
echo “ $a is greater”
else
echo “$b is greater”
if


OUTPUT:

            [csestaff@localhost csestaff]$ sh big.sh

Enter the first number
3
Enter the second number
5
5 is greater

RESULT:
            Thus, the shell script is written to find the biggest among given two numbers and its output is verified.
