Demonstrate the '$#' Variable using Linux Shell Script

The source code to create a Linux shell script program to demonstrate the "$#" variable is given below. The given program is compiled and executed successfully on Ubuntu 20.04.

Linux shell script program to demonstrate the '$#' variable

#!/bin/bash

# Program name: "total_command.sh"
# Linux shell script program to demonstrate the "$#" variable.
echo "Total command line arguments are: $#"

Now, we will save the shell script program with the "total_command.sh" name.

Output

$ sh total_command.sh  1 2 3 4 5
Total command line arguments are: 5

Explanation

In the above program, we used the $# variable to get the total number of the command-line argument passed. Here, we passed the argument total using the echo command on the console screen.
