I have two files: log_ca.txt and log_aa.txt
contents of log_ca.txt:
333333333->ca_filename3
444444444->ca_filename4
111111111->ca_filename1
222222222->ca_filename2
contents of log_aa.txt:
111111111->aa_filename1
333333333->aa_filename3
222222222->aa_filename2
444444444->aa_filename4
The program extracts the values after the -> delimiter of both files
Makes an association between the values on both of the files.
Meaning, this is desired output:
CA FILENAME => AA_FILENAME
---------------------------
ca_filename1 => aa_filename1
ca_filename2 => aa_filename2
ca_filename3 => aa_filename3
ca_filename4 => aa_filename4
Suggested code:
print "CA FILENAME => AA_FILENAME\n";
print '-' x 27, "\n";
open my $ca, '<', 'log_ca.txt' or die $!;
my %ca;
while ( <$ca> ) {
chomp;
my ($k, $v) = split /->/;
$ca{$k} = $v;
}
open my $aa, '<', 'log_aa.txt' or die $!;
foreach ( sort <$aa> ) {
chomp;
my ($k, $v) = split /->/;
print "$ca{$k} => $v\n";
}
Outputs I'm getting
(see "double pop" in code below for details)
CA FILENAME => AA_FILENAME
---------------------------
=>
ca_filename3 => aa_filename3
ca_filename4 => aa_filename4
and
(after adding the "double pop" below prints all records but still get
the => delimiter)
CA FILENAME => AA_FILENAME
---------------------------
=>
ca_filename1 => aa_filename1
ca_filename2 => aa_filename2
ca_filename3 => aa_filename3
ca_filename4 => aa_filename4
Questions:
How do I get the desired output without resorting to the 'double pop'?
See suggested change below.
How do I get rid of the extra "=>"?
That is also taken care of if you change those lines as suggested.
<snip>
foreach(@ca_files_sorted){
s/[\r\t\n]+//; #Remove carriage returns and new lines
my @temp = split (/\d+->/, $_);
push @ca_filenames, @temp;
That does not do what you think it does. Check the contents of @temp to
see what I mean.
You probably want to replace the two latest lines with:
my ($temp) = /\d+->(.+)/;
push @ca_filenames, $temp;
foreach(@aa_files_sorted){
s/[\r\t\n]+//; #Remove carriage returns and new lines
my @temp = split (/\d+->/, $_);
push @aa_filenames, @temp;
Ditto.
#why do I need to put [EMAIL PROTECTED] twice?
Because @ca_filenames and @aa_filenames contain empty elements.
