I'm writing a script intended to run under bash in OS X. I have Markdown files that look like this:
# File name
## Heading 1
Some text
## Heading 2
* List item 1
* List item 2
## Some other section
...
I'm trying to read everything inside Heading 2 into a variable, and I've tried using sed, grep, and perl, but can't get a working solution. Of those tools, it looked to (in theory) be possible and easiest with Perl, especially given that I need multiple lines. It looks like this regex works (at least with javascript syntax):
## Heading 2\s+(.+)\s+
I'd like to keep it a one-liner, and stick to only tools available on stock OS X (El Capitan, 10.11). Assume I only know "Heading 2" up front, not the following header caption.
