linux command to show processes

[Aramax]

I have Ubuntu linux installed. I have no problem in using Linux when it is the Graphical User Interface. I'm quite weak with commands. I want to know which command shows the process manager like the windows task manager. Or any other some related command would help too. Thanks!

To stop processes by name i.e. to kill process :
