I was thinking of a code to split a given directory path
(e.g. 'foo/bar/rab/oof') and retreave all parent directories
to receive something like this: 
'foo'
'foo/bar'
'foo/bar/rab'
'foo/bar/rab/oof'

The code I came up with is as follows:

sub get_parents {
    my (@p, $o);    
    for (split ("/",$_[0])) {push(@p,"$o/$_");$o.="/$_"}    
    return \@p;
}

(here's a quick test for 'perl -e' command:

  perl -e '$p="foo/bar/rab/oof";for (split ("/",$p)) {push(@p,"$o/$_")
+;$o.="/$_"} print join("|",@p);'

)

However, is there any better/quicker way of doing the same thing? I know it
does sound rather trivial...

Thankx.
