Pasting text into index.html from bash?

Question

linux

The essence of the problem is what. There is a code, conditionally Yandex metric. The code uses a lot of special characters (pipes, quotes, etc.), you need to insert this code from the shell into index. The index has a label where to insert it (a certain keyword that can be replaced with a code. The code is conditionally in the file. I tried SED, but due to the presence of an abundant number of special characters, this is very problematic.

Answer 1

Well, if there is only one place to insert, then it's easier to split index.html into 2 files, before the keyword and after.
Then output these files to the resulting file mixed with the desired code
cat before.index.html > index.html
mysupercommand >> index.html
cat after.index.html >> index.html

Answer 2

replacement in awk. read the embed code into the variable and replace gsub(). this should not cause problems, unlike gray hair.
