Replace using SED + Vars + New Line












0















I'm trying to use a "sed" with new line, but I want to use this new line in a var like this:



#!/bin/sh
var1='tags'
var2='aw1 n
aw2 n
aw3'

sed -i ':a;N;$!ba;s@'"$var1"'@'"$var2"'@g' *.html


I want to repĺace a pattern tags in my document to a many lines inside my var2.



BEFORE:
tags


AFTER
aw1
aw2
aw3

  • :a;N;$!ba reads many lines. Do you need this? In your example are those blank lines after tags deliberate? As if you wanted to replace many lines with many lines. But var1 is not multi-line, so it's not really clear. Please edit the question and clarify.

If I understood it correctly, it should be as simple as replace every ENTER with "n". Like:



sed "s/tags/aw1naw2naw3/g" file



Do not use both (ENTER and n). Let me know if I understood the problem.



and... I just forgot: If you need to put it in a variable, you should "double escape" the n. Like



v=tags;
c=aw1\naw2\naw3;
sed "s/$v/$c/g" *.html

  • It’s (IMHO) simpler to put the string in quotes; i.e., c='aw1naw2naw3' or c="aw1naw2naw3".
