If your question is about the scripting language itself, it belongs more on Stack Overflow. If your question is about automating a task, it belongs more on Super User, or on more specific sites such as Unix and Linux (for scripts running on unix and unix-like systems), Server Fault (for tasks related to administering multiple computers), and potentially Android Enthusiasts, Ask Different, Ask Ubuntu if your script is for these respective platforms.
If it's a unix shell scripting question, Unix and Linux gets a lot of those (generic shell questions, questions about specific shells, how to do stuff from the command line, etc). There are questions about the behavior of shells, both for scripting and interactiely, as well as questions asking how to script small tasks such as text processing, file management, renaming files, finding files, etc.
