Yes, but it's likely you're not going to like it...

Install Text::CSV, and use the following script:

#!/usr/bin/perl # use strict; use warnings; use Text::CSV; $ARGV[0] or die "Usage: $0 <filename> [<filename>] ..."; my ( $template_file_name, $templateText, %hash ) = ''; my $csv = Text::CSV->new( { binary => 1, eol => $/ } ) or die "Cannot use CSV: " . Text::CSV->error_diag(); for my $csvFile (@ARGV) { print "\nProcesing file $csvFile ...\n"; open my $csvfh, '<:crlf', $csvFile or die "Unable to open $csvFile +: $!"; # Ignore column names in first line my $columnNames = $csv->getline($csvfh); # Get vars from second line my @vars = @{ $csv->getline($csvfh) }; # Process each csv line while ( my $row = $csv->getline($csvfh) ) { my $templateFN = pop @$row; if ( $template_file_name ne $templateFN ) { $template_file_name = $templateFN; undef $templateText; } # keys: fields from second line; values: fields from csv line @hash{@vars} = @$row; $templateText //= getTemplateText($template_file_name); my $templateTextCopy = $templateText; $templateTextCopy =~ s/$_/$hash{$_}/g for keys %hash; my $ofile_name = $hash{'##rtrname##'} . '.txt'; print "Writing to file: $ofile_name\n"; open my $fh, '>', $ofile_name or die "$ofile_name: $!"; print $fh $templateTextCopy; close $fh; } close $csvfh; } print "\nDone!\n"; sub getTemplateText { my ($template_file_name) = @_; local $/; open my $fh, '<', $template_file_name or die "$template_file_name: + $!"; $templateText = <$fh>; close $fh; return $templateText; }

If you try it on one machine and it resolves the uninitialized error issue, then there's more diagnostic information to work with.
