This sentence may be a little misleading. (Even though it IS basicaly
correct!)
The parend put $filename in list context. In list context a regex
match returns a list of strings that matched the groups in the regex.
In this case there is only one group so that list will have only one
item and that item will be assigned to $filename.
Now the regexp matches all non-slashes at the end of the string
(which is NOT the same as "the stuff after the last slash"! There
doesn't have to be any slash for this regesp to match!) so the
$filename ends up containing the last part of the path in $file.
(Wow this is long)
See
my $str = 'ABCDE';
my ($x, $y, $z) = $str =~ /(.)(.)(..)/;
print "$x, $y, $z\n";
