SED与多行变量替换 [英] sed replace with variable with multiple lines

问题描述

我想与跨越多行的文本替换词。我知道我可以简单地使用换行符\\ n来解决这个问题，但我想保持字符串任何不需要格式化的干净。

I am trying to replace a word with a text which spans multiple lines. I know that I can simply use the newline character \n to solve this problem, but I want to keep the string "clean" of any unwanted formatting.

下面的例子显然是行不通的：

The below example obviously does not work:

read -r -d '' TEST <<EOI
a
b
c
EOI

sed -e "s/TOREPLACE/${TEST}/" file.txt

如何实现这一点没有改变它与读开头和结尾EOI？部分任何想法

Any ideas of how to achieve this WITHOUT modifying the part which starts with read and ends with EOI?

我希望这有助于。
