Find.find("d") {|path| puts path}
I want to exclude certain type of files, say *.gif and directories.
我想排除某些类型的文件，比如* .gif和目录。
PS: I can always add code inside my block to check for the file name and directory type, but I want find itself to filter files for me.
PS：我总是可以在我的块中添加代码来检查文件名和目录类型，但我想找到自己为我过滤文件。

I don't think you can tell find to do that.You could try using Dir#[], which accepts file globs. If you are looking for particular types of files, or files that can be filtered with the file glob pattern language, it may be a better fit.
我不认为你可以告诉发现这样做。你可以尝试使用Dir＃[]，它接受文件globs。如果您正在寻找特定类型的文件，或者可以使用文件glob模式语言过滤的文件，那么它可能更适合。
eg
例如
Dir["dir/**/*.{xml,png,css,html}"]
would find all the xml, png, css, and html files under the directory d.
会找到目录d下的所有xml，png，css和html文件。

You can't make find do it, but Find may help: in the block, you need to check whether the current path is one of those you'd like to exclude or not; if so, then call Find#prune. This seems to be the standard idiom when using Find.
你无法找到它，但是查找可能有所帮助：在块中，你需要检查当前路径是否是你想要排除的路径之一;如果是这样，那么请调用Find＃prune。这似乎是使用Find时的标准习惯用法。
If you decide to use Dir#[] instead, you may call reject on its result, passing a block to exclude certain types of files. However, note that, as far as I understand, Dir#[] reads all the contents of your d directory before you can filter, while Find#prune guarantees not to read the contents of pruned subdirectories if you call it within the block passed to Find#find.
如果您决定使用Dir＃[]，则可以对其结果调用reject，传递一个块以排除某些类型的文件。但请注意，据我所知，Dir＃[]在您可以过滤之前读取d目录的所有内容，而Find＃prune保证不读取已修剪子目录的内容如果在传递给的块中调用它查找＃发现。
