A 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

echo enter a and b read a b c=`expr $a \* $b` echo $c
$ enter a and b $ 4 5 $ 20
