更换多行文字使用的sed? [英] Replace a word with multiple lines using sed?
问题描述
我工作的一个bash脚本拥有以prepare一个E-邮件发送给用户。
I'm working on a bash-script that has to prepare an E-Mail for being sent to a user.
它聚集了一些数据,这些数据最终被东西多行。对于存储在 $ DATA
。
It aggregates some data, which ends up being multiple lines of stuff. For the example stored in $DATA
.
现在,后位STFW我发现像 SED -ei的几件事S / _data _ / $ {数据} / Gmail.tpl
也< A HREF =http://stackoverflow.com/questions/6684487/sed-replace-with-variable-with-multiple-lines> SED可变换成多行的。他们没有工作。
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,如何获取 SED
来取代多行文本的东西吗?
Now the question is, how do I get sed
to replace something with multiple lines of text?
(替代 SED
也欢迎!)
推荐答案
如果你用你的多行文本 \\ n
S,这将用一个简单的工作 SED
命令:
If you build your multiple line text with "\n
"s, this will work with a simple sed
command as:
DATA=`echo ${DATA} | tr '\n' "\\n"`
#now, DATA="line1\nline2\nline3"
sed "s/_data_/${DATA}/" mail.tpl
