Overview of the OA and the final exam 📖
In Linux Foundations WGU D281 , there will be no Pre-assessment to prepare you for your final exam. Instead the module requires you to sit for the Linux Professional Institute (LPI) Linux Essentials 010 certification at the end of the mudule. This might not be the typical course structure of a WGU course, but do not worry, we will guide you through the entire ordeal and show you the way to achieve your goals. After you have sat for this professional exam, you will be credited with a certificate to validate your knowledge in this field.
The LPI Linux essentials exam structure is as follows;
- Number of Questions: 40
- Time Allocated : 60 minutes (1 hour)
- Venue : Online proctored or physical location
- Question Type : MCQ and fill in the blank questions
- Other Information : The exam should be scheduled through Pearson VUE
As this exam covers the fundamentals of Linux, you won’t have to stress about a vast amount of course content or complex theoretical concepts. If you’re already experienced with Linux platforms, this exam will be a walk in the park for you. If not, fret not—you’ll soon become a Linux expert. All you need to do is follow our study guide, and you’ll be well on your way 🙂 The test comprises just 40 questions, and the exam time set for examinees is quite generous as well. It is expected that you will not require more than 30 minutes to complete the exam with your proper command over the course material..
A typical exam taker will encounter 37 multiple-choice questions and 3 fill-in-the-blank questions. Despite your study materials containing labs, there won’t be any performance-based questions or lab scenarios in your final exam.
One crucial tip for passing this exam is to memorize the Linux console commands and their uses. These commands play a significant role in the final exam, so it’s essential to memorize and understand all of them beforehand. The best way to memorize these commands is to put them into practice yourself—either by going through the labs or using a Linux virtual machine. Hands-on experience with these commands will ensure they are committed to your memory.
Another valuable tip is to utilize the elimination method when tackling the multiple-choice questions. If you’re unfamiliar with this technique, it involves reviewing the provided answers for each multiple-choice question and systematically eliminating the incorrect options. This method helps narrow down the possible answers, increasing your chances of selecting the correct one, even if you’re unsure. If you can eliminate three answers, the remaining one is likely correct. If you eliminate at least two answers, you’ll have a 50% chance of guessing the correct answer.
By employing these tips and methods, you’ll have a significant advantage in the certification exam. All you need to add to the mix is confidence in yourself.

Filesystem Hierarchy Standard (FHS)
In Linux, the Filesystem Hierarchy Standard (FHS) defines the structure and organization of directories within a Linux distribution. It provides guidelines for where different types of files and directories should be located in order to maintain consistency and compatibility across different distributions. Here’s a brief overview of some key directories specified by the FHS:
| /bin | Essential user command binaries. This directory typically contains executable files that are required by all users, such as basic system commands like ls, cp, mv, etc. |
|---|---|
|
/boot
|
Files required for the boot process, including the Linux kernel, boot loader configuration files, and other related files. |
|
/dev
|
Device files, representing hardware devices and system resources. These files allow access to devices such as disks, terminals, and printers. |
|
/etc
|
System-wide configuration files. This directory contains configuration files for various system components and applications, including network configuration, user authentication, and system startup scripts.
|
|
/home
|
User home directories. Each user on the system typically has a subdirectory within /home where their personal files and settings are stored. |
|
/lib and /lib64
|
Shared libraries required by programs in /bin and /sbin. /lib contains 32-bit libraries on 64-bit systems, while /lib64 contains 64-bit libraries. |
|
/media and /mnt
|
Mount points for removable media and temporary filesystems, respectively. Removable devices such as USB drives are often mounted under /media, while temporary filesystems can be mounted under /mnt. |
|
/opt
|
Optional application software packages. This directory is typically used for installing software that is not part of the core system distribution. |
|
/proc
|
Virtual filesystem providing information about processes and system resources. It contains files and directories that represent running processes, system configuration parameters, and hardware information.
|
|
/root
|
Home directory for the root user. Unlike regular user home directories, /root is the home directory for the superuser (root), the administrative account with full access to the system.
|
|
/sbin
|
Essential system binaries. Similar to /bin, but contains binaries that are primarily used for system administration tasks and require root privileges to execute. |
|
/srv
|
Data directory for services provided by the system. This directory is used to store data files and other resources used by network services such as HTTP, FTP, and NFS servers. |
|
/tmp
|
Temporary files. This directory is used for temporary storage of files that are only needed temporarily and can be deleted without harm.
|
|
/usr
|
Secondary hierarchy containing read-only user data and programs. It typically includes directories such as /usr/bin, /usr/sbin, /usr/lib, /usr/include, etc., which contain user binaries, system administration binaries, libraries, header files, etc.
|
|
/var
|
Variable data files. This directory contains files that may change frequently during normal system operation, such as log files (/var/log), spool files (/var/spool), and temporary files (/var/tmp). |

Pipping into Files and Variables
In Linux, piping is a powerful feature that allows you to redirect the output of one command as input to another command, enabling you to chain commands together to perform more complex operations. Piping into files and variables are common use cases for piping in Linux.
Piping into Files:
To pipe the output of a command into a file, you use the > or >> redirection operators.
- > : Redirects output to a file, overwriting its contents if the file already exists.
- >> : Redirects output to a file, appending it to the end of the file if it already exists.
For example:
Piping into Variables:
In bash, you can capture the output of a command into a variable using command substitution, which involves enclosing the command within $(…) or backticks `…`.
For example:
In both cases, the output of the command is stored in the variable, allowing you to manipulate it further within your shell script or command line.
Piping into files and variables provides a flexible way to manage command output, allowing you to capture and manipulate data as needed in your Linux environment.
