in reply to My split command isnt working - please advise

Given the data you've shown I'm sure not you need the first split (check for what split uses as a default).
#!/usr/bin/perl #use v5.12.2; use strict; use warnings; while(my $line = <DATA>){ chomp $line; my @nums = split(/\./, $line); print "@nums\n"; } __DATA__ 1.2.56.3 3.55.7.3

[Your Mother]: They would think so.
[jdporter]: ok, I need a recipe for piping lines "through" an external program which is itself a filter
[jdporter]: without using a tmp file
[1nickt]: tobyink perl -MTypes::Standard= is_Int -Mstrict -wE 'say 1 if is_Int 1.0'
[jdporter]: so that I can use the existing expand unix util. Otherwise, I'll probably use Text::Tabs.
[1nickt]: pryrt I guess I don;t really care if user 42 logs on as 42.0 ... more of an academic question at this point.
[LanX]: jdporter: open PIPE,'-|' ?
[LanX]: oh you want the result line by line?
[jdporter]: ok, LanX, then what?
[jdporter]: It doesn't have to be line by line. Just "my program" "writes" to the external prog and also/then "reads" from it.
