To show Markdown files in browsers, I found a way without temporary files: https://gist.github.com/Boldewyn/4311962

It uses data: URIs for fun and profit:

x-www-browser $(base64 -w0 | cat <(echo -n 'data:text/html;base64,') -)
#  ^--- Debian link to default browser
#               ^---- base64 slurps stdin as default
#                            ^--- concat the "data:" header, then the content

It's still working after ~10 years. 😊 Thanks!

Installed with brew install browser 👉 Tested on MacOS Mojave 10.14.6 👍

Works perfectly! Thanks Chris. Oh.. and thanks for making Github! 🙂

Small heads up for an improvement: open can be replaced by xdg-open to make this work on Linux. Maybe the script could detect if it is used on Mac/Linux and use the correct command based on that.

Here's @geoff-nixon's version as a standalone Bash script, with support already baked in for Quick Look or some other previewer. Requires bash to be somewhere in the search path if you're on Mac; should mostly work on Linux, too.

Note this was removed from Homebrew in January.
