in thread next unless - and then 'until'

I want the snippit to check each file in the directory but only do that once. After it has check each file in the directory I want it to follow a goto statement.

Step back, and explain what you want to accomplish, and forget how think you want the code to work. It sounds like you want to filter a directory based on some condition, then do something with that list. Forget the goto - if you are doing something until something, then just fall out of the bottom of the loop.

# untested opendir( my $dh, $some_dir ) or die "can't opendir $some_dir: $!"; my @files = grep { ...some condition... } readdir( $dh ); closedir $dh; # there, now do whatever you wanted to `goto` here, # iterating or whatever over @files # ...

Update: generalized.
