1. Define a variable holding the regex you want to use.
    • my $dot = qr/^[^\.{1,2}]/;
    • This checks to see if the string begins with a period or two (.) or (..)
  2. Check out http://perldoc.perl.org/functions/our.html
    3. for more info... about 'our' and 'my' for defining variables. In your example - my will work fine.
  3. Use your defined variables in the grep, shown below.
Happy grepping, Dawn 


my @list = qw(. .. test.xls file100.pl);

my $dot = qr/^[^\.{1,2}]/;

my @files = grep { /$dot/ } @list;

foreach my $file(@files) {
        print "$item\n";
}
