Hi,
I'm sure this question has been asked before, but I can't seem to find an answer using super search...
I have a file which is 22 columns delimited by a tab. I want to sort it first by column 9, then by column 22. I'm not sure how to proceed in modifying the Schwartzian transform to accomplish this. This is what I have, but it doesn't seem to be working:
@sortedarry =
map { $_ ->[0] }
sort { $a->2 <=> $b->2 }
sort { $a->[1] cmp $b->[1] }
map {
my @cols = split /\t/;
[$_, $cols[9], $cols[22] ];
} @foo;
print "$_\n" foreach @sortedarry;
