== symlinks? ==
Just curious, how many of these hand rolled solutions can deal with a symlink (or hardlink) to a higher directory (i.e. cyclic graph)? If encountering one, would it bail with "pathname too long", or loop until memory exausted? --[[User:Ledrug|Ledrug]] 04:56, 13 June 2011 (UTC)
:'''In Python,''' the [http://docs.python.org/library/os.html#os.walk full docs for os.walk] show that by default, symlinks are not followed. There is an optional parameter that allows symlinks to be followed and a banner note states:
::'''Note:''' Be aware that setting ''followlinks'' to True can lead to infinite recursion if a link points to a parent directory of itself. walk() does not keep track of the directories it visited already.
:There is also a note and '''warning about using relative pathnames''' and the assumption that code will not change the current directory during calls to os.walk. --[[User:Paddy3118|Paddy3118]] 06:04, 13 June 2011 (UTC)
