Question

I have the folder structure like below

resources/folder1 , /folder2 , /folder3

Now I want this text to be prepended with newlines:

{% extends '::layout.html.twig' %}
{% block body %}

and this should appended at the bottom

{% endblock %}

of all the files in folder and sub-directories under Resources. Is this possible?

Answer 1

Change directory to resources, create two template files: BEGIN and END.

File: BEGIN

{% extends '::layout.html.twig' %}
{% block body %}

File: END

{% endblock %}

Run commands:

sed -i '1s/^/\n/' */*
sed -i -e '1rBEGIN' -e '$rEND' */*
sed -i '1d' */*

No backslashs escaping any more, this solution is very clear and simple and scales well.
