As written, the \( \) are unnecessary in your example. The reason that this doesn't work is that cygwin's filesystem name reporting is not very good. Try 'find / -maxdepth 1 -printf '%f:%F ' to see what I mean. /proc is listed as "unknown", not "proc", as its fstype, so your above attempt was failing to prune /proc (and hence, that explains why you were traversing /proc/registry). As to why it is different now that you upgraded cygwin: a patch was added that allows readdir() to return virtual directories from within the root directory, where previously it did not. And /proc is a virtual directory. So the behavior, while not necessarily nice, is expected; and serves to illustrate the need to be careful with find when crossing file system boundaries. Try -xdev, instead of -fstype ... -prune. > As far as I know the syntax for the find command should work as above. Only if cygwin were to be patched to actually provide find with the information it needs to see /proc is -fstype "proc" rather than "unknown". cygwin.com/acronyms#PTC. However, if updatedb is trying this, maybe I should look into patching that. - -- Life is short - so eat dessert first!
