Hello Monks,
I have a strange behaviour on simple file reading. I would like simply read the lines, while the scripts interpoles something, or trunk the lines.

I don't know what exactly is happening, so please can you explain?

This code on Windows works as well, while on Ubuntu 64 bit (Perl 5.10) the line of code are trunked.

The file to read: directories.txt:

# text 1
# text 2
# text 3
# text 4
# text 5
/home/wolf/Scrivania/foto-recco
/home/wolf/Scrivania/rescue
[download]

The code:

    use FindBin qw ($Bin);
    
    my $test='hello';
    my $ref2Test=\$test;
    my $source="$Bin/directories.txt";
    
    open DIRECTORIES, "<",$source;    
    
        while(<DIRECTORIES>) {
    # chomp;
        
        print "this is \$_: $_\n";
    
        
       print "An that is my string:\n";
        print
                "initial $$ref2Test middle '$_'  final ";    

        print "\n----------------------\n\n";
            
    }
        
    close DIRECTORIES;

Output without chomp line (but I need to chmop):

this is $_: # text 1

An that is my string:
initial hello middle '# text 1
'  final 
----------------------

this is $_: # text 2

An that is my string:
initial hello middle '# text 2
'  final 
----------------------

this is $_: # text 3

An that is my string:
initial hello middle '# text 3
'  final 
----------------------

this is $_: # text 4

An that is my string:
initial hello middle '# text 4
'  final 
----------------------

this is $_: # text 5

An that is my string:
initial hello middle '# text 5
'  final 
----------------------

this is $_: /home/wolf/Scrivania/foto-recco

An that is my string:
initial hello middle '/home/wolf/Scrivania/foto-recco
'  final 
----------------------

this is $_: /home/wolf/Scrivania/rescue
An that is my string:
initial hello middle '/home/wolf/Scrivania/rescue'  final 
----------------------

Output with chomp:

<br /><br />this is $_: # text 1
An that is my string:
'  final ello middle '# text 1
----------------------

this is $_: # text 2
An that is my string:
'  final ello middle '# text 2
----------------------

this is $_: # text 3
An that is my string:
'  final ello middle '# text 3
----------------------

this is $_: # text 4
An that is my string:
'  final ello middle '# text 4
----------------------

this is $_: # text 5
An that is my string:
'  final ello middle '# text 5
----------------------

this is $_: /home/wolf/Scrivania/foto-recco
An that is my string:
'  final ello middle '/home/wolf/Scrivania/foto-recco
----------------------

this is $_: /home/wolf/Scrivania/rescue
An that is my string:
initial hello middle '/home/wolf/Scrivania/rescue'  final
