Note that on Linux and macOS, shell scripts must be marked as executable: not doing so for these scripts will result in a permission error during the GitHub Action. Windows does not have such a permission system, but you can mark a script nonetheless with git:
git update-index --chmod=+x {name_of_script}Then commit and push.
