UNIX Operating Systems and File System Part 1: Key Assignment Draft
During this week’s IP, you will submit a first draft of your Key Assignment from Weeks 1–4.
Part 2
This IP will have you describe the various file permissions that a file might have. You should also describe the setuid permissions. Next, you will be required to set the file permissions on all of the class files so that only the file owner can
access the DB and IP files, only the group participants can read the Key Assignment files, and everyone else has no access.
In addition, many UNIX operating systems utilize the UNIX file system (UFS). Linux can use the extX file system. Describe the
features of these 2 file systems and describe at least 1 additional file system feature for each platform. Complete the
following:
