Hello! I got a weird print output for the line of code: print "******processing <<<<${file}>>>\n\n"; One output is ******processing <<<</home/user/projects/database/bwa/index_bwa_human_b36_both.fasta.tar.gz>>> Another output is actually the following which is weird >>>***processing <<<</home/user/projects/database/bwa/index_bwa_human_b36_both.fasta.index.tar.gz.md5 The input file where I got the file name has the following line: 
[13:06 yunfei@bcl code]$ cat -T -E ../src/db_names | grep "hg18ibwa"
$g18ibwa^Iindex_bwa_human_b36_both.fasta.tar.gz^Iindex_bwa_human_b36_b
+oth.fasta.index.tar.gz.md5

The code for reading file names is (file path is added thereafter by $file="$dir/$file";) 
102         while(<DBNAME>) {
103                 next if /^#/;
104                 1 while (chomp);
105                 s/ +/\t/g;
106                 s/\t+/\t/g;
107                 my @tmp=split('\t',$_);
108                 my $item=shift @tmp;
109                 $down_name{$item}=\@tmp;
110         }

Also when I try 
130                         if ($file =~/(zip$)|(gz$)|(tar$)|(bz$)|(bz
+2$)/i) {
131                                 $untar{$file}=$untar_dir;
132                                 print STDERR "Got $file another ta
+r file\n";
133                         } elsif ($file =~/md5$/i) {
134                                 my ($source_file)= $file=~/(.*)\.m
+d5$/i;
135                                 print STDERR "Source file $source_
+file\n";
136                         }

I only got output from line 132 but never from line 135. Any idea what's wrong here? Thank you very much! I'm new to this place, hope I'm asking the question at the right place.
