Tasklist.exe equivalent in linux

Question

I want to develop a task manager in Ubuntu Linux. I have a task manager in windows that I am running in Eclipse. I am getting the output. But in Linux, what is the equivalent method for "tasklist.exe" to find the processes running?

Please help me..

you can use the ps command to determine the user, process, usage and other trivia.

Don't you consider top as an equivalent of tasklist.exe?

ps -ef will get you all of the tasks running

man ps will get you all of the options

import java.io.BufferedReader;
import java.io.InputStreamReader;

public class psef
{

public static void main(String args[]) throws Exception
{

    try
    {
        String line;
        Process p = Runtime.getRuntime().exec("ps -ef");
        BufferedReader input = new BufferedReader(new InputStreamReader(p.getInputStream()));
        while ((line = input.readLine()) != null)
        {
            System.out.println(line);
        }
        input.close();
    }
    catch (Exception err)
    {
        err.printStackTrace();
    }
}
}

@Nathan Fellman I just udpated/posted the code -- he didnt say what he was really trying to do until his comment. I suspect that in his code, he didnt grab the output with an InputStreamReader... – Stuart Siegler Apr 19 '12 at 13:34
i have done the part till getting the contents for a task manager in the console and writing it into a file. Now from the file, i need to selct only the contents to be displayed in a msgbox say for ex., PID,CM,CPU%,MEM%. Is there a command in linux to choose except the 'CUT' cmd? Pls help me in going about this – celebrate celeb Apr 26 '12 at 08:49
post this as a new question, with the output you have and output you need – Stuart Siegler Apr 26 '12 at 11:56
Hi, I have done the initial part and the msgbox displays all that I need to display (Image name,PID,Session name,Session#,Memory usage). I have separately developed a window with 5 tabs using java swings. Now i want to put each of these displayed results into tabs. How do I go about doing this? Kindly help me since I am a beginner. Thanks... – celebrate celeb May 04 '12 at 05:10
