USING UNIX/LINUX COMMAND LINE IN TERMINAL.

What letter (character) would you type while top(1) is running (interactive command) to: (a) sort process by decreasing percentage-of-memory usage? (b) print the command the user typed to start each process. For instance, a process may be running a program called 1s, but the user may have typed "/bin/ls -lah" to start it. By default, top shows (just) the program name in the COMMAND field. Hence, in this example top will report (just) "ls". What character would you type to top while it is running to have it display "/bin/ls -lah" for this process instead (and analogously for all other processes)? Include output from top to demonstrate the effect of the character you specified/typed. A cut-and paste of the interactive window is fine. Hint: recall one can search through a man page by pressing / and entering a regular expression pattern. Press N to advance to the next match and Control + Nto see the previous match
