Launch top with filters?

Question

Is there a way to run top with these filters by default:

filters: '%CPU>0.0' + '!COMMAND=top'

?

Can I pass that via command line options?

Answer 1

top -i

This option does exclude zombie and idle processes. And it sorts CPU usage greater than zero.

Answer 2

top:W to save current view configuration

Using W command through top interactive CLI. For more details see man top → Files.

An example, of the saved configuration:

more ~/.config/procps/toprc (Ubuntu 21.10)

~/.toprc (Ubuntu 18.04) top does not save or restore filters with W command. I don't know yet when it did change.
