bash - chmod:仅当文件是目录时执行

Question

我知道 chmod -R u=rwX,g=rwX,o=r 将设置目录、子目录和文件，但要注意:

The capital X permission option tells chmod to grant execute access only if it makes sense -- if the item is a directory, or already has at least one execute access enabled (i.e. if it appears to be an executable file).

但是有没有办法强制 chmod(以类似的方式)只影响目录，而让所有文件保持原样？
