Re^2: File Input and Output

in thread File Input and Output

I m having trouble using this in a script. I have a test file that looks like :

open(my $fh1, ">>", "outputcontrol.txt"); open(my $fh2, ">>", "outputoutput.txt"); while ( <> ) { my $count = ($_ =~ y/x//); print "$count \n"; # print $_; if ( $count != $delim_amnt_per_line ) { print fh1 $_; } my ($prefix) = substr $_, 0, 7; next if $seen{$prefix}++; print fh2 $_; }

Its supposed to do some checks on delimiter per line and remove duplicates based on a substring, my problem is that i have zero output on the filehandles. Whereas if i ran it with just print it would print normally, both expected outputs on STDOUT. Can someone help me?

    You replied to a node from 2007, its author was last here 1 year ago.

    Nevertheless, when using lexical filehandles (i.e. open my $fh1, the dollar sign isn't optional. Fix:

    print $fh2 $_; # ^ # | # Here.

    ($q=q:Sq=~/;[c](.)(.)/;chr(-||-|5+lengthSq)`"S|oS2"`map{chr |+ord }map{substrSq`S_+|`|}3E|-|`7**2-3:)=~y+S|`+$1,++print+eval$q,q,a,
