The other big gotcha that took a while to sink in was find -name "foo*" -or -name "*bar" -print which should actually be find \( -name "foo*" -or -name "*bar" \) -print to do what you might expect (print things matching beginning with foo or ending with bar) Without the parens, it gets interpreted as -name "foo*" -or ( -name "*bar" -and -print ), and hence only prints things that match the latter predicate.
