Re^3: Split output by tabs

is there a way of specifying certain columns to be printed? e.g the 10th,18th and 20th column?

One way to do it - use an array slice:

{
  local $" = "\t";
  print $OUT map "@{$_}[10,18,20]\n", sort { $a->[10] cmp $b->[10] } @
+out;
}

where can i read up on in regards to skipping blank/empty values when splitting arrays? Something is wrong wrt your question, since you don't split arrays, you slice or join them. Do you mean omitting empty fields splitting a record, or omitting empty/undefined array elements joining an array?	[reply]

Sorry I meant, the original file (orders) has blank values in some columns, i'd like for them to be omitted from the results (orders_today.txt) i.e not printed, is that possible?	[reply]
