Yes, there is. The -r option tells rm to be recursive, and remove the entire file hierarchy rooted at its arguments; in other words, if given a directory, it will remove all of its contents and then perform what is effectively an rmdir.
The other two options you should know are -i and -f. -i stands for interactive; it makes rm prompt you before deleting each and every file. -f stands for force; it goes ahead and deletes everything without asking. -i is safer, but -f is faster; only use it if you're absolutely sure you're deleting the right thing. You can specify these with -r or not; it's an independent setting.
And as usual, you can combine switches: rm -r -i is just rm -ri, and rm -r -f is rm -rf.
Also note that what you're learning applies to bash on every Unix OS: OS X, Linux, FreeBSD, etc. In fact, rm's syntax is the same in pretty much every shell on every Unix OS. OS X, under the hood, is really a BSD Unix system.
I was looking for a way to remove all files in a directory except for some directories, and files, I wanted to keep around. I devised a way to do it using find:

-r“递归”
-f“force”（禁止确认消息）
小心！
-r "recursive"
-f "force" (suppress confirmation messages)
Be careful!
将删除当前目录中的所有内容（文件夹和文件）。
但要小心！ 仅当您完全确定您位于正确的目录中时才执行此命令。
Would remove everything (folders & files) in the current directory.
But be careful! Only execute this command if you are absolutely sure, that you are in the right directory.
是的，有。
-r选项告诉rm是 r 递归的，并删除以其参数为根的整个文件层次结构；换句话说，如果给定一个目录，它将删除其所有内容，然后执行有效的 rmdir 操作。您应该知道的另外两个选项是
-i和-f。-i代表i互动；它会让rm在删除每个文件之前提示您。-f代表force；它会继续删除所有内容而不询问。-i更安全，但-f更快；仅当您绝对确定您正在删除正确的内容时才使用它。您可以使用-r指定这些，也可以不指定；这是一个独立的设置。和往常一样，您可以组合开关：
rm -r -i只是rm -ri，rm -r -f是>rm -rf。另请注意，您正在学习的内容适用于每个 Unix 操作系统上的

本质上，它使用正则表达式来选择要从结果中排除的目录，然后删除剩余的文件。

Essentially it uses regex to select the directories to exclude from the results then removes the remaining files.
