Re^2: comparing lines of data

Thankyou tybalt89

Could I ask another ?

Could you adjust that code so that it will read the input data from a file called input.txt

and print the match data to match.txt and no match.txt ?

Or should I ask as a new question ?

Thanks again :)

Could I ask another ? No! (Just kidding :) ... adjust that code so that it will read the input data from a file ... and print the match data to [files] ... Please see also perlintro, open, perlopentut, and some of the articles in Input and Output, such as File Input and Output (but use the modern "three argument" call to open; the latter article is old and often uses "global" filehandles in its examples).

To read from a file, all you have to do is : `my $Filename = “...”; my $Filehandle; open $Filehandle, ‘<‘, $Filename or die “cant open file.\n”; my @Lines = <$Filehandle>; close $Filehandle; ...` [download]	[reply] [d/l]

Better to let open report why opening fails should that occur: `open(my $fh, "<", $filename) or die "Can't open $filename: $!";` [download]	[reply] [d/l]
