Determine Operating System in Kotlin

This article explores different ways to programmatically determine the current operating system from Kotlin.

We can access the System’s environment variables with the System.getProperty() function. The idea is to get the os.name system property to determine the operating system.

Following is a simple example demonstrating this:

enum class OS {

WINDOWS, LINUX, MAC, SOLARIS

}

fun getOS(): OS? {

val os = System.getProperty("os.name").toLowerCase()

return when {

os.contains("win") -> {

OS.WINDOWS

}

os.contains("nix") || os.contains("nux") || os.contains("aix") -> {

OS.LINUX

}

os.contains("mac") -> {

OS.MAC

}

os.contains("sunos") -> {

OS.SOLARIS

}

else -> null

}

fun main() {

when (getOS())

{

OS.WINDOWS -> println("Windows Operating System")

OS.LINUX -> println("Linux Operating System")

OS.MAC -> println("Mac Operating System")

OS.SOLARIS -> println("Solaris Operating System")

else -> println("Unknown Operating System")

}

Output (may vary):

Windows Operating System

That’s all about checking the operating system in Kotlin.
