Re^3: 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.

    Can you provide wider context? I'm a little confused.
