Hi,
I am having troubles with a variable that should not be defined but
seems to be somehow. In the following code, the variable $localdir is
declared, then I am doing a find, and in case I get a result the
returned path is assigned as a value to $localdir. But somehow the
latter IF results to TRUE (=$localdir is defined) although the find does
not return a path (which is ok for my current test). Please could tell
me what I do not understand? I thought this was the proper way to check
whether a variable has a value or not (or at least my Perl book says
so)!?
*** snip ***
my $localdir;
if (defined $localdir) { print "defined 1: $localdir\n"; } #
undefined = ok for this test
my $find = File::Finder->type('d')->name("$sdir")->print;
$localdir = find ( $find, "$dbpath/dumps");
if (defined $localdir) { print "defined 2: $localdir\n"; } #
DEFINED although no directory :-(
*** snip ***
Kind regards,
Nora
