How do I get top to quit similarly to the way less quits, that is, not leaving behind its output on the screen?
This is the version I have:
procps-ng version 3.3.9
When I play a movie with SMPlayer (video:mpv) and I check my CPU usage with GNOME system monitor, it shows %4 or %5 CPU usage (1 second update interval), but htop shows %45 CPU usage:
top shows the same load as htop:
Since My CPU fan RPM goes higher when I'm playing movie with SMPlayer. I suspect top is reporting CPU usage more accurately.
I have Intel i7 920 with 6GB RAM.
Why do I have high CPU usage and why do I see different results on top and in GNOME system monitor?
Why are some processes highlighted in top? Does highlight have special meaning? Thanks!
How can I configure 'top' to show all values in human readable format instead of long numerics. I am using Ubuntu 14.04.
Sample output I am getting at the moment:

I want to write batch or something, that will write output of top into a file on login.
I did top >> output-file, but it contains some strange character!
Can somebody give a simple tutorial about how to write batch file in Linux?
