I'm using GitHub-Codespaces in an enterprise subscription. The environment is preconfigured with a dev-container: https://docs.github.com/en/codespaces/setting-up-your-project-for-codespaces/configuring-codespaces-for-your-project
After successful startup, I want to execute a final command on shell, example: cat /etc/os-release with a standard output on the user-terminal.
Since there is no .bashrc or .bash_profile in GitHub-Codespaces, I'm not sure how to achieve this. Do you have an idea?
