Hi, How can I stop script execution if certain condition is not met? exit() does not work here as it exit julia.

I usually avoid scripts and pack things into functions. In that way I can gracefully return if a condition is met (or not). You can also break to exit for loops, without exiting the function that contains those for loops. Hope this helps.

What do you mean by script and how did you run it? Did you mean including a file?

Hi @yuyichao Sometimes conditions cannot be met by the input provided by the user. In this case, there is no point of continuing running the code, and I would rather exit with a message. I am looking for something similar to return in MATLAB.

Something like this? function main() # code if break_condition return end # more code end main() An other advantage is that this avoids global variables, which are bad for performance.

I asked that on stack overflow once and there isn’t really a satisfactory solution to it, besides just throwing an error: https://stackoverflow.com/questions/35226337/how-to-quit-exit-from-withing-included-file-file

That isn’t what I asked. The question is what you meant by “script execution”. If you indeed mean by includeing a file, then no there’s no global control flow. You could throw an error to abort execution but you should just use a function instead.

I think that I understand the question from @hmemy Java, Python, C/C++, Fortran, etc. provide a system function that will immediately exit to the resident operating system. Python: sys.exit(n). Java: System.exit(n). It doesn’t matter if the caller is the main program, a function, or an included …
