    Linux Processes & Their Purpose


    I am attempting to learn what all the processes do on a standard Ubuntu 12.04 LTS distro.

    For example, the process "modem manager." I want to know it's purpose. When I google this process, I get all kinds of issues related to the process but, not what the process' intended function is.

    I am looking for a compiled list, website, resource or anything that will allow me to create a simple table:

    [Process Name] : [Purpose of process]

    The idea being to kill or not even start those processes that are not needed (Bluetooth, for example).

    The purpose of any process is to run a program. That's all that processes do. The name you see in listings is the name of the program which that process is running.

    If you want to know the purpose of the program, start by using the whatis command, e.g. whatis modem_manager.

    man modem_manager or info modem_manager will give you more information.

    Turning off daemon processes that you don't use makes good sense, especially if you have linited resources.
