Getting a Shell in the Docker Desktop Mac VM

2021 Update: Easiest option is Justin's repo and image

Just run this from your Mac terminal and it'll drop you in a container with full permissions on the Docker VM. This also works for Docker for Windows for getting in Moby Linux VM (doesn't work for Windows Containers).

docker run -it --rm --privileged --pid=host justincormack/nsenter1

org-mode syntax - superscripts and subscripts example 1

org-mode syntax - superscripts and subscripts example 1

  • Add #+OPTIONS: ^:{} to your org-mode file to explicitly enable superscripts and subscripts.
superscripts
To create a superscript put ^{ characters at the start of the superscript text and } at the end of the superscript text, e.g. word^{superscript} will render as wordsuperscript.
subscripts
To create a subscript put _{ characters at the start of the subscript text and } at the end of the subscript text, e.g. word_{subscript} will render as wordsubscript.
