使用 sed 用多行替换一个单词? [英] Replace a word with multiple lines using sed?

问题描述

我正在编写一个 bash 脚本，它必须准备发送给用户的电子邮件.

I'm working on a bash-script that has to prepare an E-Mail for being sent to a user.

它聚合了一些数据，最终变成了多行内容.对于存储在 $DATA 中的示例.

It aggregates some data, which ends up being multiple lines of stuff. For the example stored in $DATA.

现在，经过一些 stfw 我发现了一些东西，比如 sed -ei "s/_data_/${DATA}/g" mail.tpl 和 sed 用多行变量替换.它们都不起作用.

Now, after a bit of stfw I found a few things like sed -ei "s/_data_/${DATA}/g" mail.tpl and also sed replace with variable with multiple lines. None of them work.

现在的问题是，如何让 sed 用多行文本替换某些内容?

Now the question is, how do I get sed to replace something with multiple lines of text?

(也欢迎使用 sed 的替代品！)

(Alternatives to sed are also welcome!)

推荐答案

如果您使用 " " 构建多行文本，这将适用于简单的 sed命令为:

If you build your multiple line text with " "s, this will work with a simple sed command as:

DATA=`echo ${DATA} | tr '
' "\n"`
#now, DATA="line1
line2
line3"
sed "s/_data_/${DATA}/" mail.tpl
