Trying to kill a program via help command.

-aux errors for me, here's what I have now
ps | awk ' /program/ {print $1} '
This is outputting the PID, isn't there a way to store the number in a variable rather than print it, maybe then pipe it into a kill? I'm not sure of the syntax I guess.
edit: I meant to say via exit command in the title.
edit2: no longer relevant
edit3: break; I gotta start dumbing myself down, or reading more before trying to code.
But, pretend this was to do something other than break a loop., Let's say I am trying to find out how many times someone has logged into the machine. Use last to display all the different logins, several names pop up, some multiple times. This is something else I was working on, all I can figure out is the total number of logins, but I can't determine how to compare if $1(user name) is there more than once, and ontop of that count it if it is.
ex.
toyoung
rasmith
toyoung
output i'm looking for would be
toyoung 2
rasmith 1
here's what i have:
last | awk ' END {print "Number of logins:", NR} '
ps | awk ' /program/ {print $1} '

kill
kill(1) General Commands Manual kill(1) Name kill - send a signal to a process Syntax kill [-sig] processid... kill -l Description The command sends the TERM (terminate, 15) signal to the specified processes. If a signal name or number preceded by `-' is given as first argument, that signal is sent instead of terminate. For further information, see The terminate signal kills processes that do not catch the signal; `kill -9 ...' is a sure kill, as the KILL (9) signal cannot be caught. By convention, if process number 0 is specified, all members in the process group (that is, processes resulting from the current login) are signaled. This works only if you use and not if you use To kill a process it must either belong to you or you must be superuser. The process number of an asynchronous process started with `&' is reported by the shell. Process numbers can also be found by using It allows job specifiers ``%...'' so process ID's are not as often used as arguments. See for details. Options -l Lists signal names. The signal names are listed by `kill -l', and are as given in /usr/include/signal.h, stripped of the common SIG prefix. See Also csh(1), ps(1), kill(2), sigvec(2) kill(1)
