The columns hold information on the processes: There is a dashboard area at the top of the screen made up of lines of text, and a table in the lower part of the screen made up of columns. It provides a dynamic view of the processes running in your computer. To get an updating view of the processes, use the top command. You can provide a list of process IDs, separated by spaces. You are not restricted to one process ID. Use the -p (select by process ID) option to achieve this: ps -p 3403 Once you have found the process ID for the process you’re interested in, you can use it with the ps command to list the details of that process.
