G'day jwalker1960,

Welcome to the monastery.

Here's another way to do it (using pack):

#!/usr/bin/env perl use strict; use warnings; print pack 'A12A11A9A40A*' => split /,/ for <DATA>; __DATA__ Account,Login Name,Password,Web Site,Comments Google Docs,george123,F0oB@r,http://www.google.com/docs,The GoodleDocs + site Amazon,george123,fo0bA7,http://www.amazon.com,The Amazone Kindle site Apple,george123,mM_B39Aa,https://www.apple.com/accountmanagement,My Ap +ple account

Output:

$ pm_pack_fmt_txt.pl Account Login Name Password Web Site + Comments Google Docs george123 F0oB@r http://www.google.com/docs + The GoodleDocs site Amazon george123 fo0bA7 http://www.amazon.com + The Amazone Kindle site Apple george123 mM_B39Aa https://www.apple.com/accountmanagemen +t My Apple account

    Thanks Ken! That worked beautifully!

      If you liked the pack solution, here's a more versatile version (with some additional test data):

      #!/usr/bin/env perl use strict; use warnings; my (@data, @max); while (<DATA>) { push @data => [ split /,/ ]; @max = map { my $len = length $data[$#data][$_]; ( $max[$_] ||= 0 ) >= $len ? $max[$_] : $len; } 0 .. $#{$data[$#data]} - 1; } my $template = 'A' . join(A => ( map { $_ + 1 } @max ), '*'); print pack $template => @$_ for @data; __DATA__ Account,Login Name,Password,Web Site,Comments,Extra Google Docs,george123,F0oB@r,http://www.google.com/docs,The GoodleDocs + site,A Amazon,george123,fo0bA7,http://www.amazon.com,The Amazone Kindle site, +B Apple,george123,mM_B39Aa,https://www. ... shorter,My Apple account,C Longer Account,Login Name,Password,Web Site,Comments,D Account,Longer Login Name,Password,Web Site,Comments,E Account,Login Name,Longer Password,Web Site,Comments,F Account,Login Name,Password,Longer Web Site,Comments,G Account,Login Name,Password,Web Site,Longer Comments,H XAccount,XLogin Name,XPassword,XWeb Site,XComments,I

      Output:

      $ pm_pack_fmt_txt.pl Account Login Name Password Web Site + Comments Extra Google Docs george123 F0oB@r http://www.google.com +/docs The GoodleDocs site A Amazon george123 fo0bA7 http://www.amazon.com + The Amazone Kindle site B Apple george123 mM_B39Aa https://www. ... shor +ter My Apple account C Longer Account Login Name Password Web Site + Comments D Account Longer Login Name Password Web Site + Comments E Account Login Name Longer Password Web Site + Comments F Account Login Name Password Longer Web Site + Comments G Account Login Name Password Web Site + Longer Comments H XAccount XLogin Name XPassword XWeb Site + XComments I

      You could also use this technique to create a FORMAT for printf (as suggested by toolic++ earlier).

      Update: s/@max[0 .. $#max]/@max/
