What are your criteria? Matching "important" or "hello" somewhere in the
text? Something else? It's really not clear by your example what is to
be captured.
For example, if it's "important" or "hello" then personally I'd use
egrep and avoid the complexity of perl entirely:
$ egrep 'important|hello' asdf.txt
importantthing
another important thing
yet another thing
hello!
$ perl -ne '/important|hello/ && print' asdf.txt
importantthing
another important thing
yet another thing
hello!
