Linux Commands for Certification

By Bob Weiss and Google Bard

Many of the certification classes that I teach are requiring a deeper understand of Linux, especially Linux commands at the terminal window.  As a cybersecurity certification instructor, I know that understanding Linux commands in the terminal window is essential for anyone who wants to work in this field.

The command line is a powerful tool that can be used to perform a variety of tasks, from managing files to running programs. By learning the basics of Linux commands, you can gain a deeper understanding of how your computer works and how to use it to your advantage.

In addition, the command line is often the only way to access certain features of Linux systems. For example, you can only use the command line to create new users or groups, or to configure network settings. If you want to be able to manage your Linux system effectively, you need to be able to use the command line.

Of course, learning Linux commands can be challenging at first. But with a little practice, you’ll be able to master the basics and start using the command line to your advantage.

Here are some of the benefits of understanding Linux commands:

  • You can gain a deeper understanding of how your computer works.
  • You can use the command line to perform a variety of tasks, from managing files to running programs.
  • You can access certain features of Linux systems that are not accessible through the graphical user interface.
  • You can become more efficient at managing your Linux system.
  • You can troubleshoot problems more easily.
  • You can automate tasks.
  • You can become more productive.

If you’re interested in learning more about Linux commands, there are many resources available online and in libraries. You can also find tutorials and courses that can teach you the basics.

Here is a list of useful Linux commands.
