For readability, here's a formatted and numbered version:
My guess is that in line 14 you're trying to assign a regular expression to a variable, and use that in the match below. To do that, you'd have to use the qr// construct, and it would be much more efficient to do that outside the loop, instead of each time again.
Other than that, you can probably do the same thing with a simple grep {}, eg

lastlogin
LASTLOGIN(8) BSD System Manager's Manual LASTLOGIN(8)NAME
lastlogin -- indicate last login time of users
SYNOPSIS
lastlogin [-f file] [-rt] [user ...]
DESCRIPTION
The lastlogin utility will list the last login session of each specified user, or for all users by default. Each line of output contains the
user name, the tty from which the session was conducted, any hostname, and the start time for the session.
If more than one user is given, the session information for each user is printed in the order given on the command line. Otherwise, informa-
tion for all users is printed. By default, the entries are sorted by user name.
The lastlogin utility differs from last(1) in that it only prints information regarding the very last login session. The last login database
is never turned over or deleted in standard usage.
The following options are available:
-f file
Open last login database file instead of the system-wide database.
-r Print the entries in reverse sorted order.
-t Sort the elements by last login time, instead of user name.
FILES
/var/log/utx.lastlogin last login database
