how to check for headless server (check for $DISPLAY)

[j-lakeman]

I'd like to ignore certain files and folders in .chezmoiignore based on existence of $DISPLAY. How can that be achieved easiest? I didn’t manage to access $DISPLAY through sprig's env.

Can you provide an example of what you tried?

Within {{ if ne .chezmoi.os "darwin" }} # Linux 🐧 id like to check for $DISPLAY. I tried this:

chezmoi execute-template {{ env DISPLAY }}
chezmoi: template: arg1:1: function "DISPLAY" not defined

You need to wrap it in quotes.

Cheers, yet I still get:

chezmoi execute-template {{ env "HOME" }}                                                   
chezmoi: template: arg1:1: function "HOME" not defined

You also need to quote the template:

chezmoi execute-template '{{ env "HOME" }}'
