Please help me by suggesting the steps I should take   For this assignment, you will need two sessions open (e.g., a pair of ssh sessions, or a pair of xterms), one for answering the questions, and one for experimenting with different commands to see if they represent the correct answer. When you are satisfied with one of your commands, copy and paste it from your “experimental” window into your “question and answer” window. In either window, create a directory ~/UnixCourse/commandsAsst. Use cd to make that new commandsAsst directory your current working directory (in both of your session windows). For the remainder of the assignment, you should not cd into a different directory. In one window, give the command ~cs252/bin/basicCommandsAsst to start the assignment. This will place some files into the fileAsst directory from the prior assignment. Some of these will be text files (recognizable as such because their names end with “.txt”) and some are data files (named ending in…
