Craft Your Own Linux Commands: A Beginner's Guide to Customizing Your Terminal :B9:

Linux is a powerful and versatile operating system, but sometimes remembering all the commands can be a bit overwhelming. What if you could create your own custom commands? In this guide, I will walk you through the process of creating your own Linux command by leveraging the principle that "everything in Linux is a file." Let's replace the ls command with a custom command called "Dekhado."

Step-by-Step Instructions

Step 1: Check Your Current Directory

First, open your terminal and find out your present working directory using the pwd command. Then, list the contents of this directory using the ls command.

pwd
ls

Step 2: Navigate to the Binary Directory

Next, navigate to the binary directory where executable files are stored. Use the cd command to change directories and then list the contents using ls.

cd /bin
ls

Step 3: Copy the ls Command

In this directory, you will find the ls command. We will make a copy of this command and rename it to "Dekhado."

sudo cp ls Dekhado

Step 4: Remove the Original ls Command

Now, for demonstration purposes, we will remove the original ls command. Be cautious with this step as removing system commands can affect your system's functionality.

sudo rm ls

Step 5: Use Your Custom Command

You can now use your custom command "Dekhado" just like you would use ls.

Step 6: Restore the Original ls Command (Optional but Recommended)

To avoid any system issues, it's a good idea to restore the original ls command. You can do this by renaming "Dekhado" back to ls or by reinstalling the coreutils package.

sudo mv Dekhado ls

Or, if you prefer to reinstall:

sudo apt-get install --reinstall coreutils

Conclusion

By following these simple steps, you can create your own custom Linux commands. This can be particularly useful for simplifying command usage or adding a personal touch to your Linux experience. Always exercise caution when removing or altering system files, and ensure you have proper backups or restore points.

Happy customizing!
