ps 2. Use the ps command to view a list of processes that root is currently running. Run the command again, only this time, redirect the output to a third file called: root_processes.txt To view a file, you can use the cat command, such as: cat root_processes.txt (Redirect standard output to go to a file by using the > sign after the command and before a file name, i.e. ps -u root > root_processes.txt) 3. Use the df command with the -k option to see how much disk space is free on each partition. Re-direct this output to a file called disk_space.txt. 4. Using basic commands, find the largest file in the /usr/bin directory. (may need to research online for ideas) Who is the owner of the largest file? Explain the notations for file permissions in Linux: What are the file permissions on this file? Who is allowed to read, write, or execute the file? 5. Use the top command to see what processes are running. Note the total amount of RAM and total amount of swap space (virtual memory) as well as how much of each is presently free. See which process is currently taking up the most CPU time and note its process id (PID), who is the process owner, how much memory it is consuming (SIZE), and how much of that is currently resident in RAM (RES) (the balance being swapped to virtual memory on disk)
