Extract code excerts from markdown file

Question

I have a pandoc markdown file which has a lot of code. I want to extract all the code bits from file preferably using sed. The syntax of code in pandoc is three or more ` signs to start and finish the code segment.

```

Code is here

```

I can extract one line but I have no way of extracting between markers.

Answer 1

sed -n '/^```/,/^```/ p' < input.file

Will print all lines between ``` but including the ``` lines too. To get rid of that:

sed -n '/^```/,/^```/ p' < input.file | sed '/^```/ d'

You can find an explanation of how to use line ranges by pattern, and the 'p' and 'd' commands starting here:
