Shell scripting is a powerful tool that allows users to automate tasks and perform complex operations in a Unix-based environment. One common use case for shell scripting is generating multiplication tables. In this article, we will walk you through how to create a shell script that generates a multiplication table for a given number.
Before we dive into the details, it’s important to note that shell scripting is a skill that can be learned with practice. Understanding the basics of shell scripting, such as variables, loops, and functions, will be helpful for creating more complex scripts in the future.
Shell Script For Multiplication Table
Creating the Shell Script
To create a shell script for generating a multiplication table, open your favorite text editor and start by defining a variable for the number you want to generate the table for. For example, let’s say we want to generate a multiplication table for the number 5:
“`
#!/bin/bash
num=5
“`
Next, we will use a loop to iterate through the numbers 1 to 10 and multiply each number by the variable we defined earlier. We will then print the result to the console. Here’s the full script:
“`
#!/bin/bash
num=5
for i in 1..10
do
result=$((num * i))
echo “$num x $i = $result”
done
“`
Running the Script
Save the script to a file, for example, mult_table.sh, and give it execute permissions using the following command:
“`
chmod +x mult_table.sh
“`
To run the script, simply execute the following command in your terminal:
“`
./mult_table.sh
“`
You should see the multiplication table for the number 5 printed to your console, showing the results of multiplying 5 by the numbers 1 to 10.
Congratulations! You have successfully created a shell script for generating a multiplication table. Feel free to modify the script to generate tables for different numbers or customize the output format to suit your needs.
Remember, practice makes perfect when it comes to shell scripting. Keep experimenting with different scripts and exploring new possibilities to enhance your skills.
