Hello,

I am having a problem for which I don't quite understand the reason...

Perl complains that I am trying to redefine variables, even when I am just accessing them.

Could anyone explain this to me, please?

     1    #!/usr/bin/env perl
     2    use strict;
     3    use warnings;
     4    use Net::FTP;
     5    
     6    my $host = 'ftp.example.com';
     7    my $user = 'smith';
     8    my $pass = 'secret';
     9    my $dir_name = '/';
    10    my $target_dir = '/var/tmp/ftp-download';
    11    my $tmp_dir = '/var/tmp';
    12    my $last_index_file = '/var/tmp/last-index';
        (...)
    42    my $ftp = Net::FTP->new($host);
    43    $ftp->login($user, $pass);
    44    $ftp->cwd($dir_name);
    45    my @dir = $ftp->ls();

FIXED. There were two lines wrong I didn't quote. Instead of !~ to see whether a regular expression does not match I wrote ~! twice in the lines above that. I don't know how this could lead to the error, but it seems fixed now. 
# Append a '/' to directories if needed
if ($target_dir ~! m{\/$}) { $target_dir .= '/'; }
if ($tmp_dir ~! m{\/$})  { $tmp_dir .= '/'; }

# Append a '/' to directories if needed
$target_dir .= '/' unless ($target_dir =~ m{\/$});
$tmp_dir .= '/' unless ($tmp_dir =~ m{\/$});
