Important Things You Should Know About Linux Interview Questions

Linux interview questions can vary greatly depending on the position you’re applying for, or the employer you’re applying to. There are certain types of Linux that are considered more technical, however there are also many that are more general and easier to use. Questions about Linux are going to range from fairly basic to extremely technical, and may come from a simple “Can I change to Linux?” to a “what is the most common method for setting up Linux?”

A good way to think about the type of linux interview questions you may be asked is to think about the most basic components of an operating system. You’ll probably be asked to describe what this operating system does. Most people think of this as “how does Windows” or “why is it called Windows?” However, the basic components of this operating system are: the registry (which holds all of your computer’s settings and information), the operating system, hardware, drivers (software that allows communication between your hardware and software), and security features.

There are also many linux interview questions that relate directly to user tasks. For instance, you may be asked “What is a command shell?” This is simply a command line interface, which is a virtual environment in which you can run specific commands and create interactive applications. If you want to learn more about these kinds of linux interview questions, you can simply Google “command shells” to find websites, books, and forums to ask them. For more general linux knowledge, you can also consider looking on the many popular Linux forums.

One of the most common linux technical interview questions is “what is the best way to search for a file using grep?”. This is often asked because most people already know how to use standard text commands like “ls -l” to list a directory. However, to answer this question, you must know how to use the more advanced commands like “grep –quiet”. This is important because it lets you perform a silent search without interrupting what you’re doing.

One of the more important functions of a Linux system is the interactive shell, or bash. Many users don’t realize it, but bash is actually a small program that boots up your computer and serves as your command line environment. Many people know that bash is used for managing graphical user terminals, but you’ll find that it is also useful for performing tasks with the terminal such as listing, moving, deleting, or creating files. For more detailed knowledge, you can consult a linux training website for a tutorial on using bash. In most cases, bash can be learned by reading a manual, but if you’re pressed for time, there are many online tutorials that will teach you how to install it quickly and easily using the aptitude of a bash master.

The second most important piece of information you should know about Linux is the linux process table, which is a hierarchy of every command that has ever been executed and every process that has been stopped. As you can imagine, when you’re trying to get your job as a Linux administrator, you will need to memorize this hierarchy, as well as all of the different processes that are related to each other. The way this process tree looks like is very important to the ability to understand what your new task is in relation to others in your department or in the office at large. Even better, there is an official process tree that can be found on the Gentoo website that you can follow to learn more about the different levels of command.

The third most important piece of information you should know about Linux is the type of kernels that are available for this operating system. The kernel is essentially the software component that coordinates all of the different software components together. There are two main types of kernels that are supported on this operating system: the kernel that comes with Gentoo and the LinX kernel. Gentoo’s kernel is based upon the Open Source operating system, while LinX is based upon the Debian operating system. There are differences between the two, which can be seen with the way LinX is begun and LinX is designed to run specific code within Gentoo.

The fourth and final most important piece of information you should know about Linux is how to explain file permissions. As mentioned earlier, Linux is a very complex system that offers many different options for configuration. In order to explain file permissions, it is necessary for the Linux administrator to describe exactly what each permission does and why it is important. For example, if you want to change the setup password of your server but do not have the authority to change it without having an administrator certificate, you would use a command like “setpax”. Of course, there are other options, but this is the basic definition.
