Please help with markup question regarding "bash"

Hi, since a view days one of my RasPis is running GRAV; it has been set-up with the skeleton “”.

To my question:
When I use the markup term

$ ls -lha

which sh


it seems not to recognice the language. When I replace “bash” with “java” or “c” it seems to recognice the respective language and starts to colorice the output.

What am I missing? (Just to give that info as well: replacing “bash” with “sh” or “shell-script” is not working either.)

Thanks in advance for your support!
