muba already helped you with the basics, which were quite well explained. muba++. Text::CSV is a wrapper over Text::CSV_XS and Text::CSV_PP. Whatever is developed in Text::CSV_XS is copied into Text::CSV_PP making them behave exacly the same, but the XS version is up to 100 times as fast. Both act on streams of data, wheather that is a file or a pipe. That means that these modules do not allow to go "back" into the stream to look at previous lines. As muba already mentioned, getline_hr_all can be very handy here.

If you need to do many lookups, like in a spreadsheet or a database, consider using DBD::CSV (when you are acquainted with DBI) or Spreadsheet::Read, which enables you to look at CSV file with the eye of a spreadsheet and enables you to direct access any field in a CSV data structure.

One final remark about your original code. The "loop" could easily be shortened a lot:

my @ftpFiles =$ftp->ls ();                                            
+                                                       
my $i = 0;

while ($i < $#ftpFiles) {                                             
+                                                      
    if ($ftpFiles[$i] =~ m/andv/) {
        $ftp->get ($ftpFiles[$i]);
        $myfile = $ftp;
        }
    $i++;
    }
$ftp->quit ();

=>

foreach my $file (grep m/andv/ => $ftp->ls ()) {
    $ftp->get ($file);
    $myfile = $file; # <= your original code probably does not do what
+ you want
    }
$ftp->quit ();

update: corrected mumba to muba. sorry.
