I have been testing some code on a smaller scale and something is confusing me. Why does the  print "$csv2\n"; command at the end of this script print each full line of the csv. $csv2 has been populated with the key data of csv2hash, so I'm confused as to why it would print each line? Is each line considered a key in this instance?
#!/bin/perl my @csv2 = (); # Creates new empty array @csv2 open CSV2, "<csv2" or die; # Creates the file handle CSV2, input +s the data from csv2 into CVS2 @csv2=<CSV2>; # populates @csv2 array with data from file handle + CSV2 close CSV2; my %csv2hash = (); # Creates empty hash csv2hash for (@csv2) { # for data in @csv2 array #chomp; my ($title) = $_ =~ /^.+?,\s*([^,]+?),/; #/define the data whic +h is the title #Indicate that title data will input into csv2hash $csv2hash{$_} = $title; } foreach my $csv2 (keys %csv2hash) { # iterates over all the keys in %c +sv2hash, assigning each one to $csv2 my $value = $csv2hash{$csv2}; print "$csv2\n"; # This prints the data line by line in the csv2
