* in shell matching terms means .* in regex terms
.. in shell matching terms means \. in regex terms
cvs is the same

Where does the value in $flist come from? If you are originating it then say
my $flist = qr(^.*\.cvs$);

instead of

my $flist = "*.cvs";

If the user is supplying the value, well I think there is a module
that will turn a shell match into a regex. You might look at
Regex::Common.
