The terminal, also known as the command line interface (CLI), is a text-based interface for accessing computer systems. It provides a powerful way to control and automate various aspects of your computer, from executing basic commands to managing complex system tasks.

In this post, we'll take a look at some of the benefits of using the terminal, as well as some of the basics to get you started.

Benefits of using the terminal

One of the biggest benefits of using the terminal is that it allows you to perform many tasks more quickly and efficiently than if you were using a graphical user interface (GUI). For example, you can execute a command in the terminal to find and replace text in multiple files in just a few seconds, whereas it could take several minutes when using a GUI.

Additionally, the terminal provides a consistent interface across different operating systems, which is particularly useful for developers who use multiple platforms. The basic commands for managing files and directories are the same among Windows, Linux, and macOS, which makes it easy to switch between platforms without having to learn new tools and interfaces.

The terminal also provides the ability to automate complex tasks by executing scripts, which can save time and increase productivity. You can write scripts that automatically update your software, download new files, or back up your data. This automation can save you a significant amount of time and effort, and can also help ensure that your computer is up-to-date and secure.

Unlike a GUI, terminals provide advanced functionality. You can use the terminal to manage system processes and services, which is beneficial to system administrators and developers. Powerful tools for text processing and manipulation, beneficial specifically to developers, data scientists, and anyone who needs to manipulate a large amount of data can also be found within the terminal.

For your specific needs and preferences, terminals can be customized. You can change the color scheme, font size, and background color, and you can also customize the prompt to display information that is relevant to you. This can improve an individual's productivity by being more user-friendly.

As you can see, the terminal provides a powerful and flexible interface for accessing and controlling your computer, with many benefits over a GUI. It is a worthy investment of your time, to get more out of your computer.

Getting started

Some common commands to use in the terminal are:

  • ls : displays the contents of the current directory.

  • cd: allows you to change the directory

    • eg. cd user/local
  • cp: copy files from one place to another

    • eg. cp file1.txt file2.txt
  • mv: move files to a certain directory

    • eg. mv file1.txt user/local will move file1 to the user/local directory
  • mkdir - create a directory

    • eg. mkdir new_folder
  • pwd (print working directory): displays the full path of the current directory

    • eg. pwd will display user/local/my_directory
  • rm: delete files

    • eg. rm file1.txt file1 will be deleted
  • cat: allows you to display the contents of a file

    • eg. cat file1.txt will display the contents of file1
  • touch: create a new file

    • eg. touch file1.txt
  • nano: open and edit a text file using a basic text editor

    • eg. nano file1.txt will open file1 in a nano text editor

This isn't a comprehensive list, but these are some of the more common use cases of commands to use in the terminal. As you become more familiar, you can explore some more advanced functionalities and commands like the ones listed below.

Wrapping it up

In conclusion, the terminal is a powerful tool that can greatly enhance your productivity and efficiency as a user. From navigating file systems to executing commands and automating tasks, the terminal provides a flexible and versatile environment for you to work in. With a little practice and patience, you'll be amazed at what you could accomplish with the terminal. So, if you haven't already, what's stopping you from exploring it?
