Sys

The Sys module is a collection of operating-system utility submodules, each offering a self-contained piece of functionality:

• Sys.Console reads from and writes to the console.
• Sys.Env accesses environment variables, command-line arguments, and system properties.
• Sys.Exit terminates the running JVM.
• Sys.Process starts and manages external processes, with Sys.ProcessHandle and the Sys.StdIn, Sys.StdOut, and Sys.StdErr stream wrappers.
