given a file with a variable number of lines I want to grab lines that

@ARRAY=

I would wager it is like =
@array = $fileToSearch =~ /([\w\d]*) - ([\w\d]*) - ([\w\d]*)/ # to
process the while file
or would I have to loop it for each line and push the results onto the
array?
You don't *have* to, but you should. You usually don't want to store
the entire file's contents in memory. It's wasteful, and is not
expandable to large files.
my @array;
push @array, /([\w\d]*) - ([\w\d]*) - ([\w\d]*)/ while <$fh>;
If you *really* are opposed to that and want to do it all at once, you
could use a map:
my @array = map { /([\w\d]*) - ([\w\d]*) - ([\w\d]*)/ } <$fh>;
But again, that's strongly not recommended.
