I'm guessing these are kernel modules. They are never really relevant to my interests.

I had submitted this question to reddit, and this is the answer I got.

This is what I ended up adding to my ps alias:

ps -fN --ppid 2

It isn't "kernel modules". You've called up : report process status

It's a list of things which are running.

What do you mean hide? Why do you want to hide it?

See http://linux.about.com/od/commands/l/blcmdl1_ps.htm

It's not clear from your rather terse question what you are interested in seeing, so we're sorta flying blind here... but to narrowly answer your specific question using your specific example, you could pipe the output of your ps command through grep, thus:

ps -ef | grep -v -e '^root .*[[:digit:]] \['

...to weed out the lines you mentioned, though that could also remove any "normal" lines that happened to match that expression.

I prefer that "ps -fN --ppid 2 -C init,kthreadd" approach to the grep-based one I suggested. Nice.
