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.

Perfect timing again. We just started learning how to digest logs and were told to look at the awk, sed, and cut commands. You just finished the trifecta, thank you and I don't know if I said it before but congratulations on having over 1k subs.
so glad that these videos are helpful. and thanks for helping me reach 1k subs!
In my case, I’m looking for the last 8 bytes of lines with variable length. At the moment I’m thinking grep (maybe sed?) with a positional parameter. We’ll see.
Fantastic question! Here is one possible way of doing it:
since cut doesnt have a specifier for selection from the end of the line, you can use the "rev" command to reverse the line, then select the bytes you want, then reverse the line again:
$ rev inputfile.txt | cut -b 1-8 | rev
Like I've mentioned many times, there are MANY ways of doing any task in Linux. Any viewers have another way of doing this using cut or other tools? Please post and share
Thank you for the clarification, Blue Monkey. Good job. Like, Subscribe :)
P.s. Jak Spravy means How are you doing ;)
