Hi all, below is the code that I've written. The first step is to unzip the files and later on convert them to csv files. So the question is, how to use Getopt to get to the final output without outputting the unzipped files? Now when I run the script, the clock.sum.rpt.txt and import.clock.rpt.txt will be produced. How to sort of hide them? 

use strict;
use warnings;
use Getopt::Long qw(GetOptions);
use IO::Uncompress::Gunzip qw(gunzip $GunzipError);

#Unzip .gz files into .txt files
# In command line run
# perl getOptsLong -orig <file1_name> -new <file2_name> 

#GetOptions(
#    'orig = s'=> $input_1
#    'new = s' => $input_2
#    'out = s' => $outfile_2
#);

my $input_1 = "clock.sum.rpt.gz";
my $output_1 = "clock.sum.rpt.txt";
gunzip $input_1 => $output_1       
    or die"gunzip failed:$GunzipError\n";

my $input_2 = "import.clock.rpt.gz";
my $output_2 = "import.clock.rpt.txt";
gunzip $input_2 => $output_2
    or die "gunzip failed:$GunzipError\n";

#Convert to cvs 
open my $infile_1, "<", $output_1 or die $!;
open my $outfile_1, ">", "clock.sum.rpt.csv" or die $!;
#$header_1 = "Clock,Sinks,Buffers,Cells,Slew,Path,Vio,Area";
my $lines_1;
while(<$infile_1>){
    if(/(\w+|\S+)\s+(\d+)\s+(\d+)\s+(\d+)\s+(\d+.\d+)\s+(\d+.\d+)\s+(\
+d+)\s+(\d+.\d+)/g){
    tr/ /,/s;
    
    print $outfile_1 "$_";
    $lines_1 = $_;
    }else{
    #$lines_1 = $_;
    #warn "WARN: This line does not follow the normal output pattern, 
+";
    }
}

#print $outfile_1 $header_1;
print $outfile_1 "$lines_1\n";

close $output_1;
close $outfile_1;

open my $infile_2, "<", $output_2 or die $!;
open my $outfile_2, ">", "import.clockrpt.csv" or die $!;

my $lines_2;
#my @columns_2 = ('Clock','Time','Waveform','Types','Sources');
while(<$infile_2>){
    if(/(\w+)\s+(\d+.\d+)\s+(.\d+\s+\d+.\d+.)\s+/g){

    tr/ /,/s;
    print $outfile_2 "$_";
    $lines_2 = $_;
    }else{
    #$lines_2 .= $_;
    #warn "WARN: This line does not follow the normal output pattern, 
+";
    }
}
#print $outfile_2 "@columns_2\n";
print $outfile_2 "$lines_2\n";

close $output_2;
close $outfile_2;
