I have a text file which I managed to split the text and print out to an outfile but when it comes to the rest of data I do not know how to proceed.I am new to perl so sorry if I come off as I do not know what I am doing. I really trying to learn but this is very difficult for me. 
my $infile = "COSC146_project01_dataset_2.txt"; #project input file.
my $outfile = "fileoutput.txt"; # assigned an output file.
open FILE,$infile or die "failed to open!"; #open project text.
open OUT, ">fileoutput.txt" or die "failed to output!";
my $line = undef; #read line by line. Assigned global value to the sca
+lar line.

my $text = <FILE>;

# Split on spaces.
my @items = split ' ', $text;

use Data::Dumper;
#print Dumper(@items);

 print "$items[0]\t";
 print "$items[2]\t";
 print "$items[1]\t";
 print "$items[3]\t";
 print "$items[18]\t";
 print "$items[23]\t";
 print "$items[34]\t";
 print "$items[36]\t";
 
print OUT "$items[0]\t";
print OUT"$items[2]\t";
print OUT"$items[1]\t";
print OUT "$items[3]\t";
print OUT"$items[18]\t";
print OUT "$items[23]\t";
print OUT"$items[34]\t";
print OUT "$items[36]\t";

^^^ is what I have. i have to generate a report for management that looks similar to this, but consolidates each set of four rows and eliminates many of the columns. Your report should be an output file created by your Perl code. The columns to keep in your report are the following: 
'Date of Test', 'G400-TYP', 'G400-SN', 'G400-Ver.',
'G400-USER', 'Mode', 'Result', 'DS400-SN.', and 'DS400-Name' Again, re
+alize that, for each set of four
rows, you may not simply check 'Result' for 'ERR' in the first of each
+ four-row set.
G400-TYP G400-SN. G400-USER G400-Ver. Sensor-Typ Sensor-SNSensor range
