i hate to be snarky, but guessing is not the way to become a good
programmer. maybe in 100 more tries you will get it.
do you know what the PATH means? this is the same for all common
OS's. it is a list (usually : separated) of directories to search for a
program. is /usr/bin/lpr a directory? what would $ENV{"lpr"} even mean?
is there some global value known to exec and other calls that is 'lpr'?
programming requires understanding of what things mean and their
relationships. before i give you another answer, please read perldoc
perlvar and see what it says about %ENV. also search google for unix
PATH and learn more about that. and also perldoc perlrun on -T and what
tainting is and how you work with it.
