Nonetheless, even if you feel like a near master of regular expressions, equally critical to an expressionвЂ™s success is how it is implemented within a given tool.

Though there is a definite regex learning curve (itвЂ™s really not that bad), knowing how to use regular expressions translates directly to performing effective and efficient searches for/of artifacts during an investigation. Regardless of whether this is your first time hearing about regular expressions or if you use them regularly albeit with some level of discomfort, I HIGHLY suggest you take the time to learn and/or get better at using them вЂ“ they will be your most powerful and best friend for grep. And, nearly everyone at some point feels likeвЂ¦ Some of you may have been using it for a while. To some, this may be the first time youвЂ™ve even heard that term or вЂњregexвЂќ (shortened version of it). Grep is one of the most useful command-line utilities for searching within files/content, particularly for the ability to use regular expressions for searching/matching.

In highlighting the problems, I will also help you identify some workarounds IвЂ™ve learned and developed over the years in addressing these issues, along with an overarching solution at the end to install GNU core utilities on your Mac (should you want to go that route).

Rather than going into aspects of this discussion that have already been covered such as how Linux and BSD generally differ, I would instead like to focus on a few core utilities commonly used in/for DFIR artifact analysis and some caveats that may cause you some headache or even prevent you from getting the full set of results youвЂ™d expect. And, the differences can range from those that can cause a simple nuisance to those that can cause oversight of critical data. Well, IвЂ™m here to sayвЂ¦ thy basic command line utilities art not the same across different distributions. How and why could/would they possibly differ? I mean, theyвЂ™re basic command line tools. Have you ever wondered if/how *nix command line utilities may differ across distributions? Perhaps it never even occurred to you that there was even a possibility the tools were any different.
