The man page says that if path is omitted in find [path...] [expression] the current directory is used. I don't know if it's just that way for GNU find, or if it's standard Posix find behaviour. Regarding the wildcards in search statements, I usually just need to match a case-sensitive substring, so I use something like: find -name '*sub*' I don't know of any weird wildcard reactions, but that may be because I don't usually use complex searches or matches. One last thing, if you don't mind all the "./" prefixes, "find ." (or just "find") is just like "du -a" without the block counts.
