I have what I think is a really simple problem to solve (preferably with OS X / *nix terminal tools rather than windows command line).

I have a manuscript formatted in markdown with # (H1) denoting a chapter heading. I would like to break this large file up into smaller chapter files as I'll later be converting the manuscript to epub / mobi with pandoc. This separate-file-per-chapter format is the the recommended format according to the pandoc docs ( ) and also makes the editing process a little less unwieldy. Interestingly it is similar to what some other projects have done e.g.

I was thinking that this would be possible with a simple python script or using something like sed but I just don't know where to start. Any help would be great!

You're looking for the csplit tool.
