All You Ever Wanted to Know about Your Processes

Most process management tools require you to know something about the processes you want to manipulate. If nothing else, you must know the process's PID number to use most process-management tools. Knowing how much CPU time, memory, or other system resources a process is using is also helpful; this information can point you to the source of system performance problems or help you head off such problems. Most of these tools are text-based, but some GUI tools serve much the same function as the more traditional tools.
