Hi Mahesh,
We have lot of ways to do this i can suggest you some ways,
On customizing your code you can use like,
use strict;
use warnings;
open (RD, "input.txt") or die;
my @Read = <RD>; close (RD);
open (WR2, ">>output.txt") or die;
my $count=0;
my $C="2001-1041";
my $found=0;#######Temporary variable to find the content in whole fil
+e
for (my $read=0; $read <= $#Read; $read++)
{
if($Read[$read] =~ /$C/)
{
$count++;$found++;
}
}
print WR2"$count=$C\n" unless($found);
In other way without reading the file in array, you can do like,
use strict;
use warnings;
open (RD, "input.txt") or die;
open (WR2, ">>output.txt") or die;
my $count=0;
my $C="2001-1041";
my $found=0;#######Temporary variable to find the content in whole fil
+e
while(<RD>){
if($_ =~ /$C/)
{
$count++;$found++;
}
}
print WR2"$count=$C\n" unless($found);
You can do like this also
use strict;
use warnings;
open (RD, "input.txt") or die;
my $input;
do{
local undef $/; ######To undef the input record separator '$/'
$input=<RD>;
}; #####To read the whole file in single scalar variable
open (WR2, ">>output.txt") or die;
my $count=0;
my $C="2001-1041";
while($input =~ /$C/g)
{
$count++;
}
print WR2 "$count=$C\n" unless($count);
