A bit OT to your direct question, but just as an idea:

it's sometimes useful and easy to also use the shell as a helper.

You could write a shell script vet.sh containing

perl -ne 'print $_ if /'$1'/' $2

which invoked as

./vet.sh Vet Test.txt

would also do what you asked for. As a side benefit, your oneliner is written down - just in the case you do not remember it well a week later when you need it again. :)
