The Fundamentals of Tech Commands

Here are some basics that you need to know before you get started:

What is a Tech Command?

A tech command is a simple instruction you give to your computer or device. It’s like telling your friend to grab you a glass of water—but instead of your friend, it’s your computer doing the work! There are different kinds of tech commands:

  • Command line: These are typed out, like secret codes in a movie.
  • Voice commands: You just say what you want, and your computer listens!
  • Software commands: These are the buttons and menus you click in apps.

Way back when, people had to use lots of switches and wires to tell computers what to do. But now, we have easier ways like typing or talking.

The Anatomy of a Command

Tech commands are like short sentences. They have a main word (the command) and sometimes extra words (arguments) that tell the computer more.

For example, the command copy tells the computer to copy something, and the argument tells it what to copy. It’s like saying, “Copy this file to that folder.” Computers are picky, so you have to use the right words and punctuation (syntax) for them to understand.

Some Common Commands

Here are some really useful commands you’ll see a lot:

  • cd: Change to a different folder.
  • ls: See what’s inside a folder.
  • mkdir: Make a new folder.
  • cp: Copy a file or folder.
  • mv: Move a file or folder.
  • rm: Remove (delete) a file or folder.

The Command Line Interface (CLI)

The command line is like a direct phone line to your computer. Instead of clicking buttons, you type commands. This might seem old-fashioned, but it’s very powerful!

You can do things much faster and tell your computer exactly what you want. There are different kinds of command lines, like Bash, Zsh, and PowerShell, but they all work in similar ways.

Voice Commands

You’ve probably heard of voice assistants like Siri, Alexa, and Google Assistant. They let you talk to your computer and ask it to do things, like play music or set a timer.

Voice commands are getting better all the time, and who knows? Maybe one day we’ll mostly talk to our computers instead of typing!

Now, let’s go ahead and imrpove your Tech Command skills. You’ll be able to do even more amazing things:

Connecting Commands (Piping)

Imagine your commands are workers on an assembly line. Piping lets you pass the output (result) of one command to another command as input.

This lets you do more complex things by combining simple commands.

  • Example: ls | grep "txt" – This will list all the files in the current directory and then filter the results to only show files that contain “txt” in their names.

Sending Output to Files (Redirection)

Want to save the results of a command for later? Redirection is the way to do it.

  • Example: ls > myfiles.txt – This will save the list of files in the current directory into a new file called “myfiles.txt.”
  • Example: cat myfiles.txt – You can then use the cat command to view the contents of your saved file.

Environment Variables

Environment variables are like special storage boxes that hold important information for your computer and programs. You can access and use this information in your commands.

  • Example: echo $HOME – This command will print the path to your home directory, which is stored in the HOME environment variable.

Editing Text in the Command Line

You don’t need a fancy text editor to make changes to files! You can edit them directly in the command line using tools like Nano or Vim.

  • Example: nano myfile.txt – This will open the file “myfile.txt” in the Nano editor. You can then make changes and save them using simple commands.

Scripting: Your Computer’s To-Do List

A script is a set of commands that you save in a file so your computer can run them all at once. This is super helpful for automating repetitive tasks.

  • Example (Bash):

echo "Hello, world!"

Save this as a file (e.g.,, make it executable (chmod +x, and run it (./ to see it in action!

More Advanced Tricks

Once you’ve mastered the basics, you can explore even more powerful techniques:

  • Regular expressions: Learn the syntax of regular expressions to search for and manipulate text with incredible precision (e.g., grep "error.*[0-9]+" mylog.txt to find lines containing “error” followed by numbers).
  • SSH: Use SSH (ssh username@remote_host) to securely connect to other computers for remote management or file transfers.
  • Package managers: Easily install and manage software with commands like apt install (Debian/Ubuntu) or brew install (macOS).
  • Aliases and functions: Create your own custom commands for complex tasks or frequently used sequences.

Beyond the Basics

The command line is a vast and powerful tool. Explore specialized commands for tasks like networking (ping, traceroute), database management (mysql, psql), and web development (curl, wget).

Utilize tools like grep, awk, and sed for text processing, and master scripting to automate any task imaginable.
