G'day reaper9187,

Here's my take on a solution:

$ cat fred.dat
"A","B","C","D"
"A","B","C","D,E,F"
"A","B","C","D"
"A","B","C","D,R,T"

[download]
$ perl -Mstrict -Mwarnings -E '
while (<>) {
    my ($start, $end) = /^(.+?)("[^"]+")$/;
    my @finals = split /,/ => substr $end, 1, -1;
    say $start, q{"}, shift(@finals), q{"};
    say q{ } x length($start), q{"}, shift(@finals), q{"} while @final
+s;
}
' fred.dat
"A","B","C","D"
"A","B","C","D"
            "E"
            "F"
"A","B","C","D"
"A","B","C","D"
            "R"
            "T"

to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
