@unix

Given @unix? a : b, do a on Unix systems (including Linux and OS X) and b elsewhere. See documentation for Handling Platform Variations in the Calling C and Fortran Code section of the manual.

Examples

The @unix macro in Julia allows you to execute code specifically on Unix systems (including Linux and OS X) and provides an alternative code to execute on other platforms. Here are some examples and considerations for using the @unix macro:

Execute code on Unix systems:
```
julia> @unix println("This code runs on Unix systems")
This code runs on Unix systems
```
This example demonstrates how to execute code specified within the @unix macro on Unix systems.

Execute code on non-Unix systems:

julia> @unix println("This code runs on Unix systems") : println("This code runs on non-Unix systems")
This code runs on non-Unix systems

In this case, the code after the : is executed on non-Unix systems, such as Windows.

Using variables and expressions within @unix:

julia> @unix begin
           a = 10
           println("Value of a on Unix systems: ", a)
       end : begin
           a = 20
           println("Value of a on non-Unix systems: ", a)
       end
Value of a on non-Unix systems: 20

You can include multiple statements or expressions within the @unix macro, including variable assignments and complex code blocks.

It's important to note that the behavior of @unix is dependent on the underlying operating system. Therefore, it's crucial to consider the platform variations and test your code on different systems to ensure it behaves as expected.

For more detailed information and examples, refer to the "Handling Platform Variations in the Calling C and Fortran Code" section of the Julia manual.
