What would be the result of running a script without executing permissions?

When a script is run without executing permissions, the most expected outcome is that it will indeed display an error. This is because the operating system enforces permission restrictions to maintain security and control over what actions can be performed on files. Specifically, the execution permission must be set for the user attempting to run the script; if it’s not set, the system identifies this lack of permission and prevents execution.

Generally, executing a file requires that the file owner or user has been granted executable rights. Without these rights, attempting to run the script will typically lead to a message indicating that permission is denied or that the file cannot be executed. This behavior reinforces the importance of managing file permissions properly within a Linux environment to ensure both functionality and security.

Other options, such as the script running successfully or the system autonomously assigning permissions, do not align with how permission management is structured in Linux. Any prompts for permissions generally require user intervention, and only specific operations can modify permissions, not the system itself without explicit commands. Understanding these permission settings is crucial for anyone working within a Linux operating system.
