Pressing u allows you to filter by a username.
Prefixing this username with an ! (exclamation mark)
could show all user processes except the entered user.
e.g. Entering !root would show all current user
processes except root's.
Logged In: YES
Thanks for the suggestion. Unfortunately the per-user process selection is carried out in the platform specific code, so this feature would have to be added to each platform separately. I doubt that I will be able to commit to such an undertaking. Future versions of top will have a different internal organization and this sort of thing will be much easier to implement.
