ps -ef
The 'ps' command will give you all the currently running processes. Each Unix system may have slightly different options to list them. The most common would be: ps -ed or ps -ef or ps -el depending on how much information you want to see.
Use the 'ps' command. This command lists all of the processes running on the system, when they started, who the owner is, etc.
to find out the memory of each processes running on our unix/ Linux box type "PS -aux | more" would list u all the processes running with their respective processor id's (pid) and the memory used by the respective programs ... if u are running out of memory what we can do is note down the pid which is taking lot of memory and if u feel the process is not so important for u then use the command "killall"to quit or stop that particular process I am using red-hat Linux, here u can use a top command to c the amount of memory utilized by each running processes. You can use "top" or the native "prstat" in Solaris. In order to see how much memory is used by a process, not including that shared with other processes ( through shared libraries ), you can execute "pmap -x $pid" giving your processes PID.

PS (see "man 1 PS") in Linux is a program that generally comes with the operating system that allows you to see information about the running processes. pstree is a program that lets you see the processes as a tree, to see which process started which other process, for example.
