Re^2: Use Schwartzian transform across multiple files

[Sonya777]

Hi! Thanks for the comment! I have corrected that. Here is the upated script:

 
sonya$ vi sorting.pl
#!/usr/bin/perl
use strict;
use warnings;
use Getopt::Long;

my $version="0.2";
my $files_match="";
my $files_dir="";
my $file_name="";
my $help_flag="";
my $version_flag="";

GetOptions(
           'm|match=s' => \$files_match,
           'd|directory=s' => \$files_dir,
           'h|help' => \$help_flag, 'v|version' => \$version_flag,
);

sub sorting {
my @lines = @_;
my @sorted = map { $_->[0] }
             sort { $a->[1] <=> $b->[1] }
             map { my ($x) = $_ =~ /VerNumber:\((\d+)/i; [$_, $x]; }
             @lines;
print FILE for @sorted;
}

if (($files_match ne "") and ($files_dir ne "")) {
        chdir("$files_dir") or die "$!";
        opendir (DIR, ".") or die "$!";
        my @files = grep {/$files_match/} readdir DIR;
        my $files_size = $#files + 1;
        my $index_file = 1;
        print "Files to process: $files_size\n";
        close DIR;

        foreach (@files) {
                open(FILE, ">./sorted/$_.sort") or die $!;
                my @singlefile = $_;
                print "Processing $index_file of $files_size files: $_
++\n";
                local @ARGV = @singlefile;
                while(<>){
                       sorting($_);
                }
                close(FILE);
                $index_file++;
                print "OK: Sorted @singlefile \n";
        }
    } elsif ((!$help_flag) and (!$version_flag)){printHelp();}
"sorting.pl" [New] 49L, 1391C written

However, I am still getting the unchanged files as a result:

sonya$ ./full.pl -d /home/sonya/test/ -m file
Files to process: 3
Processing 1 of 3 files: file1.txt+
OK: Sorted file1.txt
Processing 2 of 3 files: file2.txt+
OK: Sorted file2.txt
Processing 3 of 3 files: file3.txt+
OK: Sorted file3.txt
sonya$ diff /home/sonya/test/file1.txt /home/sonya/test/sorted/file1.t
+xt.sort 
sonya$
sonya$

The standalone sorting script is working so there is something wrong with my code.
