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. This 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.
