How to Get the Current Operating System Architecture In Elixir?

2 minutes read

In Elixir, you can get the current operating system architecture by using the :erlang.system_info function with the :system_architecture atom as an argument. This function will return a string representing the current architecture of the operating system running the Elixir program. You can use this information to perform platform-specific operations or to gather information about the system the program is running on.


How to obtain the system architecture information in Elixir code?

You can obtain the system architecture information in Elixir code using the System module, which provides functions for interacting with the system on which the Elixir runtime is running.


One way to obtain system architecture information is by using the System.get_arch/0 function, which returns the architecture of the current system as an atom. You can use this function like so:

1
2

arch = System.get_arch()
IO.puts("System architecture: #{arch}")


This will output the architecture of the current system, such as :x86_64 for a 64-bit system or :arm for an ARM-based system.


Additionally, you can get information about the CPU architecture by using the System.cmd/3 function and running a system command to get the CPU architecture:

1
2

output = System.cmd("uname", ["-p"])
IO.puts("CPU architecture: #{output}")


This will output the CPU architecture of the current system, such as x86_64 for a 64-bit system.


By using these functions, you can obtain system architecture information in Elixir code.


How to write a function that returns the system architecture in Elixir?

You can use the :erlang.system_info/1 function in Elixir to get information about the system architecture. Here is an example of a function that returns the system architecture:

1
2
3

def get_system_architecture do
  :erlang.system_info(:system_architecture)
end


You can call this function in your Elixir code to get the system architecture of the current system. For example:

1

IO.inspect(get_system_architecture())


This will output the system architecture information.


What is the output format of the system architecture in Elixir?

In Elixir, the output format of the system architecture is typically represented in a diagram or a visual representation that shows the different components of the system and how they interact with each other. This can include the various layers of the system, such as the presentation layer, business logic layer, and data layer, as well as the communication protocols, data flow, and dependencies between components. The output format may vary depending on the specific tools or frameworks used to design and document the system architecture.
