This course was designed to provide information on how to use the command line environment in a Unix/Linux system to accomplish tasks such as imaging, data acquisition, and archiving. his course covers the basics of Unix/Linux commands that allow users to view and edit text files, obtain hardware and system information, partitioning and formatting, process related commands, manipulating disks and partitions, imaging, archiving, logical acquisition, live system response, and basic networking.
This would be beneficial for folks who are interested in digital forensics, incidence response, system administration, ethical hacking, or just plain linux. his course covers material for beginners as well as for advanced users. This course would also be helpful if you are considering taking the CompTIA Linux+ certification test.

I just came across your video, I think is excellent, straightforward information with great practical examples. Perhaps an early introduction to delimiters rather than late, could be useful for beginners. Keep up the good work and thank you.
Thanks for watching and thanks for the compliments. Good idea with the delimiters, i will put out something on that in the future.
Awesome Content !!
thanks for watching and thanks for taking the time to write a comment.
I have a quick question. I noticed that when you removed the comment lines, there was one comment that remained. Is that due to the 'tab' in front of the pound sign?
excellent observation!! you're the first to notice. And you are absolutely correct that one comment line remained because there was a TAB before the pound sign. My regular expression was looking for lines that start with a pound sign so that line with the TAB did not match and hence left behind.
when I pipe awk command into sed -i.bak ... I get sed: no input files. How can I save changes to the original input file.
Since sed wont be reading from a file if you are piping it with output of awk, you are really going to be doing an edit in-place. Can you give me a bit more information on exactly what you are trying to do?
