writing a script & trying to kill a process

Question

My goal is to write a script that will show all the running processes and ask the user if they want to kill each process... For each instance of a process with that name, ask the user if they would like to remove it. Remove only the processes the user answers yes (and they must type yes, not just y).

#!/bin/bash

ps

  PID TTY          TIME CMD
 1681 pts/1    00:00:00 tcsh
 1690 pts/1    00:00:00 bash
 1708 pts/1    00:00:00 script
 1710 pts/1    00:00:00 ps

echo "Do you wish to kill PID?"
select yesno in "Yes" "No"; do
case $yesno in
    Yes ) $ kill -9;;
    No ) exit;;

Im not 100% sure how to ask the question to kill each process, and how to have the PID change for each question. I know I have to create a variable, I just don't know exactly how to assign the variable to each PID...

Here is an example using a for loop:

checkit ()
{
    p="$1"
    echo "Do you wish to kill $p"
    select yesno in "Yes" "No"
    do
        case $yesno in
            Yes) $ kill -9 "$p";;
            No) exit;;
        esac
    done
}

for p in $(ps -o pid=)
do
    checkit $p
done

Check out man ps for details on customizing the ps output. Or: http://linux.die.net/man/1/ps Or: http://unixhelp.ed.ac.uk/CGI/man-cgi?ps
