Check that $tar is a true value. (Judging by what you said it *will* be true
even if $_ is corrupt ... so that's not going to help ... but check anyway.)
Otherwise, how about something like:
my $tar = Archive::Tar->new();
eval{ $tar->read($_, 1)};
if($@) {
warn "$_ is a corrupt file: [EMAIL PROTECTED]";
# Don't do anything else with this file
}
else {
> my @files = $tar->list_files() or die "Can't read
> TAR.GZ file!\n";
> #go thru the array and look for the pattern
> foreach my $tar_member (@files)
> {
> if($tar_member =~/$search_pattern/)
> {
> print "\nI FOUND 1 file!\n";
> #must extract the found file from the archive
> $tar->extract_file($tar_member, $some_path);
> }
> }
> }
} # close else block
> }, $search_directory);

If the read() succeeds on corrupt files (which I think is unlikely) then you
might have to eval{} some of the other method calls that *are* failing.
Cheers,
