Thank you for your reply, yes it helped a bit. File I need to parse is a .csv file with a fileds that must be converted to an ACLs, there are two fields: User name , asset name . One user can have either one or multiple asset names, but user name is unique. So unique user name I'm trying to use as a key and asset names I trying to use as a values of these unique keys. So one user John Doe may have either one asset name: John Doe = { "KJhkh23"} or multiple: John Doe = { "KJhkh23", "0jUfh4631",....."N"}. File was populated manually and irregulary, I mean in "User Name" field we may have one name "John Doe" but in field " Asset name" we may have a column of values. The problem is to define a first field as a key(John Doe) and the second as a value (KJhkh23), and if on the next line we can't detect a key, assume that this asset belongs to last available key (John Doe) . I'm new to perl so this code may look like a total mess for coders.

        s/\"//g;
        s/\;/\-/;
        push @tmp, $_ if $_ =~ m/^\;/ and next;
        my ($key,$value) = split /\-/, $_;
        push @tmp, $value;

        if (defined $key) {
           $current_key = $key;
            push @tmp, $value;
           $stack{$current_key} = @tmp;
}

close(SRC);
