Re: Copying files from one file to another file

my @arr= nv.txt;

my (%hash, $key, $val);

foreach (@arr) {
  $pre1="\$hash{$key}";   #previous key  of the loop
  $pre2=$val;              #previous value of the loop
  ($key, $val) = split (/:/,$_,2);
    if($pre1 eq "\$hash{$key}")  #if previous and current key same
   {
    $hash{$key}= $pre . '\n' . $val; #concatenate
    }
      $hash{key}=$val;
    print "\$hash{$key}={$vaal}\n";

input file
nv.txt has files in the form of a array like this,

test/right/case1:12: //comment
test/right/case1:344: //comment
test/wrong/case3:123:  //comment
[download]

code> output test/right/case1:12 : //comment :344: //comment test/wrong/case3:123: //comment

If the path address is same, then values should be saved in one key(path address) else different key. I think I'm not able to concatenate now or if there should be any other solution or modification, help me.

What is the name of the files you want the values saved to ? #!/usr/bin/perl use strict; use warnings; my %hash=(); # input my $inputfile = 'nv.txt'; open IN, '<',$inputfile or die "Could not open $inputfile : $!"; while (<IN>) { my ($key, $val) = split (/:/,$_,2); $hash{$key} .= $val; } # output for my $key (keys %hash){ my $outputfile = "output_$key"; $outputfile =~ s{/}{-}g; print "Writing to $outputfile\n"; open OUT,'>',$outputfile or die "Could not open $outputfile : $!"; print OUT $hash{$key}; close OUT; } __DATA__ test/right/case1:12: //comment test/right/case1:344: //comment test/wrong/case3:123: //comment [download] poj	[reply] [d/l]
