I have a csv file that i open and then sort, i have managed to do this and then save the sorted data to a new file But what i would like, is to open the file and sort and save in the same file, however when i try this i end up with a blank file. here is what i have tried so far.
#!/usr/local/bin/perl
use strict;
use warnings;
open (SORT1, "+>C:\\temp\\SORT.CSV") or die "Cannot open file $!\n";
my @sorted = map {$_->[0]}
sort { $a->[6] cmp $b->[6] ||
$a->[2] cmp $b->[2] ||
$a->[5] cmp $b->[5] ||
$a->[9] <=> $b->[9]}
map {chomp;[$_,split(/,/)]} <SORT1>;
foreach(@sorted) {
printf SORT1 "$_\n";
}
close (SORT1);
