$1 and $2 are quite volatile variables, in the sense that they only start being defined after a regex with matching groups, and that they'll have a different value after the next one. Better save it to a new variable as soon as possible after the regex.
Aside from that, this is always a good idea at the beginning of your script:
This will enable strict variable declaration (using my or our) and a few warnings that might turn into bugs down the road.
Hey,
Thank you ...
Not sure how to fix it ?
Could you please post some example of re saving variables

cupsd
cupsd(8) Easy Software Products cupsd(8)NAME
cupsd - common unix printing system daemon
SYNOPSIS
cupsd [ -c config-file ] [ -f ] [ -F ]
DESCRIPTION
cupsd is the scheduler for the Common UNIX Printing System. It implements a printing system based upon the Internet Printing Protocol, ver-
sion 1.1. If no options are specified on the command-line then the default configuration file (usually /etc/cups/cupsd.conf) will be used.
The -f option forces cupsd to run in the foreground; the default is to run in the background as a "daemon".
The -F option forces cupsd to run in the foreground but detaches the process from the controlling terminal and current directory. This is
useful for running cupsd from init.
COMPATIBILITY
cupsd implements all of the required IPP/1.1 attributes and operations. It also implements several CUPS-specific administation operations.
