To give permission to an executable file in a Unix-based system, use the `chmod` command: 1. Open your terminal. 2. Navigate to the directory containing the file. 3. Type `chmod +x yourfile` to add execute permissions. Replace `yourfile` with your executable's name. This command allows the file to be executed by the user. Always ensure you're granting permissions responsibly to maintain system security.
