git过滤所有名称为xxx的目录

使用背景：某项目中需要过滤所有名称为abcd的文件夹。

 

在.ignore文件中使用“abcd/”这样的方式只能过滤当前目录的abcd目录，对子目录或者更深层级的目录无效。

查资料发现可以使用这样的方法：/**/abcd。这样可以过滤掉所有名为abcd的目录，包括这些目录下的子目录和子文件。

 

参考内容：

　　Two consecutive asterisks ("**") in patterns matched against full pathname may have special meaning:

• A leading "**" followed by a slash means match in all directories. For example, "**/foo" matches file or directory "foo" anywhere, the same as pattern "foo". "**/foo/bar" matches file or directory "bar" anywhere that is directly under directory "foo".

• A trailing "/**" matches everything inside. For example, "abc/**" matches all files inside directory "abc", relative to the location of the .gitignore file, with infinite depth.

• A slash followed by two consecutive asterisks then a slash matches zero or more directories. For example, "a/**/b" matches "a/b", "a/x/b", "a/x/y/b" and so on.

• Other consecutive asterisks are considered invalid.
