Re^2: Appending string to all lines

It is simply a single line attempt.

#!/usr/bin/perl
use strict;
use warnings;

perl -ne 'chomp; printf "%sUF,A,Y,9,U\n", $_' test2.csv;

It generates the Bareword error. I have been reading on that topic and can see that the earlier comment pointing me to Text::CVS module is the correct approach. So that is where I'm going.

Thank you.

That should indeed generate syntax errors because `perl` is not a valid function name in Perl. You can't just type random shell commands into perl and expect it to process them like your shell would - they are completely different systems. `#!/usr/bin/perl -n use strict; use warnings; chomp; printf "%sUF,A,Y,9,U\n", $_;` [download] See perlrun for how to use flags like `-n` and perlfunc for a list of all the functions available. Note that I've made no attempt to optimise your algorithm here.	[reply] [d/l] [select]
