Grep is the command I used the most when I managed Linux Servers. It was crucial when troubleshooting errors/failures in applications. For Pentesting it’s great for finding information in a target’s environment. Knowing how to grep is a must, but I see people not using it to its fullest potential. This article will get you up to speed on what you need to know from basic to advance, and empress all your co-workers.

Highly recommend going through the OSCP certification, the amount of knowledge I gained throughout my studies was astounding. I signed up for the 90-day PWK Course in April and got my OSCP in November the same year on my third exam attempt. When I first signed up the PWK course I had very basic Penetration testing knowledge, I could barley do an easy box on Hack the Box and that’s only with hints. I do have about a year and half work experience managing/supporting Linux and Windows Servers. This did help me as I was very comfortable navigating around a server, and dealing with custom made scripts written in Bash, PowerShell, and Python. If you’re contemplating waiting or just going for it; I’d say if you have fundamental knowledge of Servers and Cyber Security then that’s good enough to start. You’ll learn what you need to as you go.

Using for-loop one-liners is a great way to speed up manual tasks. It's one of the most common commands that I use when on a Linux machine. In this article, I'll explain what a for-loop is, and how it can be modified to be a one-liner. Then provide two examples of how an Admin would use this.

An Object Oriented script to automate the tasks of Resetting Passwords, Enabling, and Disabling accounts in Active Directory. Prompts user to select which of the three action to perform. The script also allows parameters to be given, which will bypass the options and go perform the given actions. The Cmdlets used to perform these actions are Enable-ADAccount, Set-ADAccountPassword, and Disable-ADAccount.

Creating users in Active Directory is a very common task, but can be tedious to do manually. This led me to create this Object Oriented script which also supports parameters. This same object will be used in my other AD posts to allow you to add them together easily into one script. Main Cmdlet used will be New-ADUser.
