## Operating System Laboratory
Welcome to the Operating System Laboratory repository! This repository contains implementations of various operating system concepts and scripts in Bash. Whether you're a beginner looking to learn or an experienced developer seeking reference implementations, you've come to the right place.
## Cheat Sheet 😉
Using Replit
# Step-by-Step Guide: How to Use Bash in Replit.com
Replit.com is a powerful online IDE that allows you to write, run, and share code directly in your browser. Follow these steps to use Bash in Replit.
## Step 1: Create a New Repl
1. **Visit Replit:** Open your web browser and go to [Replit.com](https://replit.com).
2. **Log In/Sign Up:** If you don't have an account, sign up for one. If you do, log in.
3. **Start a New Repl:** Click the `+ Create` button on the top left of the dashboard.
## Step 2: Select the Bash Template
1. **Choose Template:** In the "Create a new Repl" window, type "Bash" in the search bar.
2. **Select Bash:** Click on the "Bash" template.
## Step 3: Set Up Your Project
1. **Name Your Repl:** Enter a name for your project in the "Title" field.
2. **Create Repl:** Click the `Create Repl` button.
## Step 4: Write Your Bash Script
1. **Open the Shell:** In the Replit IDE, you will see a file named `main.sh` opened by default.
2. **Edit the Script:** Write your Bash script in the `main.sh` file. For example, you can start with a simple script:
```bash
echo "Hello, World!"
```
3. **Save Your Work:** Replit automatically saves your changes, but you can manually save them by clicking `Ctrl + S` or using the save button.
## Step 5: Run Your Bash Script
1. **Run the Script:** Click the `Run` button at the top of the screen. This will execute your `main.sh` script.
2. **View Output:** The output of your script will be displayed in the console at the bottom of the screen.
## Step 6: Install Additional Packages (if needed)
If your Bash script requires additional tools or packages, you can install them using the terminal:
1. **Open the Terminal:** Click on the `Shell` tab at the bottom of the Replit interface.
2. **Install Packages:** Use package manager commands to install the necessary packages. For example, to install `bc`:
```bash
sudo apt-get update
sudo apt-get install bc
```
## Step 7: Explore and Share
1. **Explore:** Feel free to explore more features of Replit, such as version control, collaborative coding, and more.
2. **Share Your Repl:** You can share your project by clicking the `Share` button and copying the link to share with others.
## Example Script
Here's an example of a simple Bash script that calculates the factorial of a number:
```bash
#!/bin/bash
factorial() {
n=$1
facto=1
for ((i=1; i<=n; i++)); do
facto=$((facto * i))
done
echo $facto
}
echo "Enter a number:"
read number
result=$(factorial $number)
echo "The factorial of $number is $result"
```
## Running the Example Script
1. **Copy the Script:** Copy the above script into your `main.sh` file.
2. **Run the Script:** Click the `Run` button to execute the script.
3. **Input a Number:** When prompted, enter a number to see its factorial.

By following these steps, you can easily write and execute Bash scripts using Replit.com. Happy coding!
