    Hi Ravi

    Point 10 saving top’s output to a file saves it configuration instead.
    Please suggest in that,correct it if its wrong.
    PFB output.

      Yes its just only saves top configuration, to save the top running output to a file use the following command.

      # top -n 1 -b > top-output.txt

    Hello, I was wondering if anyone could help me by evaluating the usefulness of the top command to a technician when using it with ps and kill in order to investigate a system that is misbehaving. Thank you.
