Is there a way to prevent the last process (that is, the grep that was started at the same time as my ps command) being reported?

(I started trying to come up with a regex that would match the literal but not match itself, but that seemed, um, not the right approach...)

I run this command and got result this but not able to understand the result which node instance should i kill

 ps ax | grep node

and what S+ Sl+ T, R + Means .?

Sometimes a process comes and goes faster than I can ps aux, I tried watch -d -n0.1 "ps aux | tail" but again, that's restricted to 1/10th of a second. What I really want is to run a command and follow all new processes, one per line, as they spawn. Even processes that run fast. I know strace has abilities similar to this but I haven't been able to get it to do what I want.

tl;dr : is there a way to log all new processes?

I don't want to know much, no more than a line of ps aux would give me, for the current case I just have a process that's spawned by another and disappears, I want to be able to run it, but I don't know what the command would be. Even knowing new PIDs would be sufficient, since I could figure a script that would take these and run ps | grep on these and give me more info while the process is running (assuming hopefully the process is still around when ps gets going)

I'm running a Rails stack on Ubuntu.

When I call ps -AF, I get a descriptive process name set by the Apache module like

00:00:43 Rails: /var/www...

which is really helpful in diagnosing load issues.

But when I call top, the same process shows up simply as

ruby

Is there any way to get the ps -AF process name in top?

Using ps, I can see the size, the vsize (same as top's VIRT?), and the rss (same as top's RES?). (One more I see in top is SHR.)

Could someone summarize for me what these different fields mean?
