Like you point out, a
, if $fh
is used instead of TMP
, I lose $filehandle
as soon as $fh
is closed. So how can I unlink0
with no $filehandle
without generating "Use of uninitialized value @ /usr/local/lib/site_perl/File?Temp.pm line (1525|1584), <STDIN> chunk 1" ?
use File::Temp qw(tempfile unlink0 );
use vars qw($fh $filename);
my $template = 'fileXXXXXXXXXX';
my $dir = '/tmp/';
($fh, $filename) = tempfile($template, DIR => $dir)
or die "Error creating $filename: $!";
print $fh "\nS'working?\n"
or die "Error writing to $filename: $!";
or die "Error closing $filename: $!";
print "\nUnlinking $filename\n<ENTER> to continue, CTRL+C to abort.\n"
my $continue = (<STDIN>);
unlink0 ($fh, $filename)
or die "Error unlinking file $filename safely: $!"
I wouldn't be surprised if it's explained in the module's pod and I'm just not picking up on it.

(it's pronounced "why-bick")
Update: Good monk a says below "not supposed to close $fh... unlink0 will handle..."
A-ha! that seems to do the trick. 8^)
Update #2: But if I don't "close $fh" then "print $fh "\nS'working?\n" or die;" doesn't really happen. So I'm still doing something wrong 8^(
