Shell Script to Multiply Two Numbers

shell script is a computer program designed to be run by the Unix shell, a command-line interpreter. The various dialects of shell scripts are considered to be scripting languages. Typical operations performed by shell scripts include file manipulation, program execution, and printing text. A script that sets up the environment, runs the program, and does any necessary cleanup, logging, etc. is called a wrapper.

In this post, we will write a shell script to multiply two numbers the are taken from the input and display the output.

The first line contains two space-separated numbers: a and b

Print one number which is the product of a and b

The following is the shell script to multiply two numbers:

echo enter a and b
read a b
c=`expr $a \* $b`
echo $c


$ enter a and b
$ 4 5
$ 20
