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} '

logins - display system and user login data SYNOPSIS
groups] logins] DESCRIPTION
displays data concerning system and user logins. The format and content of the output is controlled by command options and may include: system or user login, user ID number, comment field value (for example, user name, location), primary group name, primary group ID, supple- mentary group names, supplementary group IDs, home directory, login shell, user security level, user audit events, and password aging parameters. The default data is: login, user ID, primary group name, primary group ID, and comment field value. Output is sorted by user ID, with user logins following system logins. The default output consists of login, user ID, primary group, primary group ID and comment field formatted into columns. The following options are available to this command: Display two account expiration fields. The fields show how long the account can be unused (in days) before it becomes inactive and the date the account will expire. Display logins with duplicate UIDs. Show multiple group membership data. Display with alternate format of one line of colon separated fields. Display logins with no passwords Display all system logins Sort output by login rather than UID. Display all user logins. Display extended information about selected users. This extended information includes home directory, login shell and password aging data, each on its own line. Password information consists of pass- word status (PS for valid password, LK for locked and NP for no password) and, if a password is present, date of last change, required number of days between changes, and number of days allowed between changes. In the case of non-trusted systems, the date of last change will be the latest Thursday since the change. Display all users belonging to groups, sorted by login. A comma separated list specifies multiple groups. Display the requested logins. A comma separated list specifies multiple logins. Specify a switch used to classify NIS or local users. With the option, only users belonging to the specified repository are displayed. Multiple options may be used. Any login matching any of the criteria will be displayed. A login will be displayed only once, even if it meets multiple criteria. EXAMPLES
List all logins in default format. List all logins that have no password or have a duplicate UID in default format. List all system logins in the alternate format. List all local users of the system. List all the NIS users of the system. WARNINGS
