1.Lastly, we check to see if the file is actually a directory. (See the code snippet below. ) If it is, we recurse into it.
最后，我们查看一下文件是否确实是一个目录。（请看下面的代码片断。）如果是，我们再递归进入。
2.When working with groups that may be large enough to contain breakout subgroups, it's important to use the GROUP_RECURSE option.
当处理可能包含断接子组的很大的组时，使用GROUP_RECURSE选项很重要。
3.After that, it is simple to recurse through all the nested attributes, outputting INSERT INTO SQL statements as it goes.
然后，要遍历所有嵌套的属性就很简单了，在进行中输出INSERTINTOSQL语句。
4.The GROUP_RECURSE option specifies that we do not want to add someone to the main group if she is already a member of a subgroup.
GROUP_RECURSE选项指定如果某人已经是子组的成员，则不能将这个人添加到主组中。
5.In fact, searching a collection of files is so common that grep has its own option to recurse a file system hierarchy.
事实上，搜索文件集是一项常见的工作，所以grep具有相应的选项以递归遍历整个文件系统层次结构。
6.We don't need to pass in the-string to recurse because it is already in the parent environment and does not change from call to call.
我们不必将the-string传递给recurse，因为它已经在父环境（parentenvironment）中，而且从一个调用到另一个调用时不会改变。
7.To extend the search for input files to include subdirectories, add the -recurse option to the command.
如果要将输入文件的搜索扩展为包含子目录，可向命令中添加-recurse选项。
8.It will also recurse down from the starting directory, adding files as it goes.
也会向下递归到开始目录，并在此过程中添加相应的文件。
9.It defines a closure called recurse that can be called with only one parameter rather than two.
它定义了一个名为recurse的闭包，能够只使用一个参数来调用它，而不是两个。
10.The -r option tells rsync to recurse into the directories and copy the entire structure.
r选项让rsync递归遍历目录并复制整个目录结构。
