in reply to Read a list of NUL-delimited names from STDIN to be processed

When I read nul-delimited lines from find or xargs, I usually do that with the -0 switch (which is equivalent to $/ = "\0";), and I don't chomp the data as the extra nul byte doesn't hurt after filenames.

    Well I think it could hurt in case of a Null Byte Poisoning

    Let's say you would have a null terminated file name, and would like to append the name with another string (like an index or whatever)
    Consider the following piece of code: 

    #!/usr/bin/perl -w
use strict;

my $fname = "aaa.txt\0bla";
print "NAME: $fname\n";

if ( $fname =~ /\0/ ) {
    open( F, ">$fname" ) || die "could not open $fname, reason: $!";
    close(F);
}
else {
    print "No NULL BYTE in $fname\n";
}

    It doesn't do what you would expect it to do, right?

    Of course, I may be dead wrong ....
