hi,

You can use "top", ps, glance(need license)

UNIX95= ps -e -o "user,pid,ppid,pcpu,cpu,vsz,sz,args"

GOOD LUCK!

Hi,
Virtual Memory consists of two parts, physical memory or ram and swap. The physical memory is where the programs are running, and
swap is the "spill over".
Try this command:
#ps -efx|grep [j]ava

hi,

concerning your "What is the meaning of [j] here ?" question above...

This is shell level commands for some common filename expansion and pattern matching.

For instance,

To list all of processes named "ava" with only the prefix "j" or "J", you do the following:

ps -efx|grep [jJ]ava

Likewise, if you want to list all the processes with names that cover a range, you could do the following:
ps -efx|grep [a-j]ava

so that (if they exists of course), it would return:
aava
bava
..
..
java

Read more in chap 7 on Shell programming for System Administrators in Marty's book!

hope this helps too!
