如何使用标准Linux工具将`---`-separated块替换为文本文件的内容？

Question

我有一个看起来像这样的文本文件：

Some text here. This text is not replaced.

---

And then a wild block appears!
It has stuff in it that I'm trying to replace.

---

The block is no more. Nothing to replace here. 

另一个包含要插入内容的文本文件：

A multi-
line thing to replace. 
This block is not demarcated 
in the same way
as the other

我要做的是将--- - 划分的块替换为文本文件的内容，以便它看起来像这样：

Some text here. This text is not replaced.

A multi-
line thing to replace. 
This block is not demarcated 
in the same way
as the other

The block is no more. Nothing to replace here. 

这类似于this question，但我认为不适用，因为我所处理的是一个多行块，看起来sed似乎不是很擅长那个。可以awk或ruby或其他内容吗？

未经测试，但如果不是您想要的话，将会关闭：

awk '
NR==FNR { file1 = file1 $0 RS; next }
/---/ {
    if (f) {
        printf "%s", file1
    }
    f = !f
    next
}
!f
' file1 file2
