Module kotlin-exec¶

Kotlin JVM process execution primitives with bounded capture, structured failures, explicit environment policy, and clear process ownership.

Use Exec.exec or Exec.execBlocking for managed foreground commands. Managed execution owns the child process lifecycle and terminates the process tree on timeout, cancellation, output-limit failure, or cleanup failure.

Use Exec.spawn or Exec.spawnBlocking when the caller needs a running process handle and wants timeouts on later waits to be non-destructive.

JVM-specific APIs are marked with @PlatformSpecificExecApi. Prefer the portable ExecSpec and SpawnSpec types unless a call site needs JVM-only features such as java.nio.file.Path, InputStream, OutputStream, Charset, raw Process, or virtual-thread policy control.
