display thread number in process

Hi all,
I wonder if there is any tool to display how many threads are currently running in a particular process ?
with kernel 2.4 and 2.6 ?

Thanks

Take a look at htop

I have to ask ...what advantage if any does htop have over top? From the screen shot I see less info than I get with top on my Linux servers.

to the original posters if you really want to track processes & the respective threads you can use ps -ef you'll probably want to pipe the output to more (ie: ps -ef | more )

Thanks...
htop gathers information like top...Actually I ask the question because I have a program that has 3 threads running and on a 2.4 kernel redhat, i see 3 of them displayed as separate processes (when i do ps -ef). But On 2.6 kernel, i only see 1 single.

Actually your question should due to Linux version changes. The Linux of previous v2.6(maybe) displays all user processs and threads to ps command while all have same PID. But the Linux of v2.6 just displays parent process.
Any help to you?
