A slight variation on toolic's and eyepopslikeamosquito's solutions in that I use a closure to generate the odd numbers (it returns the next odd number every time it is called) and I wrap the logic for finding duplicates in a do block to avoid leaving the %seen hash lying around after it is no longer needed.

$ perl -Mstrict -Mwarnings -MData::Dumper -e ' > my $oddNos = do { > my $val = -1; > sub { $val += 2; }; > }; > > my @array = qw{ > M94202 > M94150 > M94297 > M94150 > M94161 > M94161 > M94162 > }; > > @array = do { > my %seen; > map { > exists $seen{ $_ } > ? $seen{ $_ } > : do { > $seen{ $_ } = $oddNos->(); > $seen{ $_ }; > }; > } @array; > }; > > print Data::Dumper->Dumpxs( [ \ @array ], [ qw{ *array } ] );' @array = ( 1, 3, 5, 3, 7, 7, 9 ); $

I hope this is of interest.

    [ovedpo15]: consider the following format of strings: some_data-doesn't- matter,value. how I get the value with regex? it should be after the last comma (last string)
    [Corion]: Text::CSV_XS for all your CSV file parsing needs. Other than that, what problems do you have with perlre, and capturing everything after the comma? Also, index and substr would also work.
    [choroba]: my ($value) = $string =~ /.*,(.*)/
