( #3333=superdoc: print w/ replies, xml ) Need Help??
Hi Monks, I really hope someone can help me with my issue, I have two text files that I am attempting to compare they are in this structure: FILE 1
'abc' 'def' '121' 'xyx'
FILE 2
'def' '121'
File 3 (output file ideally) 'abc' 'xyz' however it is showing:
'121' 'abc' '121' 'xyx'
here is the code I've compiled so far, however the results are not what i desire
use strict; use warnings; my $f2 = 'cat_mapping_in_A.txt'; my $f1 = 'cat_mapping_in_B.txt'; my $outfile = '1.txt'; my %results = (); open FILE1, "$f1" or die "Could not open file: $! \n"; while(my $line = <FILE1>){ $results{$line}=1; } close(FILE1); open FILE2, "$f2" or die "Could not open file: $! \n"; while(my $line =<FILE2>) { $results{$line}++; } close(FILE2); open (OUTFILE, ">$outfile") or die "Cannot open $outfile for writing \ +n"; foreach my $line (keys %results) { print OUTFILE "$line\n" if $results{$line} == 1; } close OUTFILE;
Please can someone help me? I really don't know how to fix this Thank you
