chmod u+x makes test.pl and executable file. ./test.pl then runs it.
If you want to run one-liners type something like:
cat file | perl -e "while (<>) { print unless (/^\s*#/) }"
or the less verbose
cat file | perl -ne "print unless (/^\s*#/)"
see man perlrun or perldoc perlrun for more fun tricks
BTW: this one-liner prints all lines in file except comments
