I have some shell code that can be dangerous to run on local machine in a org-mode source code block. Globally, I have configured org-mode to prompt for execution, but I would still like to make sure that these blocks will NEVER be executed with per-block configuration.

1 Answer 1


To explicitly disable certain org-mode code blocks from execution, add :eval no or :noeval in the code block header line. See the example below:

#+begin_src bash :noeval
sudo rm -rf /

When doing C-c C-c to attempt to run the code, the following message is produced:

Evaluation of this bash code block is disabled.
  • FWIW I experienced an issue where :noeval was not preventing the code block from executing for some odd reason. Switched to :eval no and it worked.
