in reply to Parsing lines containing extra carriage returns

If bikeNomad's solution doesn't work, just split the whole thing on tabs (untested):
my $file; { local $/ = undef; # learned something ;} $file = <>; #or <FILE> } $file =~ tr/\r//d; #remove carriages my @items = split /[\t\n]/, $file; #one array of items; my $rowsize = 3; my @AoA; while( @items >= $rowsize ){ push @AoA, [splice @items, 0, $rowsize]; }
.... this works only if you're garanteed to have 3 columns.

Hope this helps,

[Corion]: Cosmic37: Ah, see perlfaq4, about How do I compute the intersection of two arrays
[Cosmic37]: I am out of practice; I use Perl for scientific programming for number crunching
[Corion]: Cosmic37: Basically, you read one file into a hash, keyed by your key, and then match the lines from the second file to that hash
[Cosmic37]: note that the two files only have datetimes which may match whereas other data per line is different format in file1 and file2 - is that really intersection?
[jedikaiti]: Hi Monks
[Corion]: Cosmic37: Well, if you want to use only parts of a line for the key, see split or whatever other mechanism to extract the key from the line
[Corion]: Hi jedikaiti!
[Cosmic37]: is there a webpage for full CB for this chat rather than side panel chat?
[Cosmic37]: thank you for advice
[Cosmic37]: peach greets jedi
