Spawns a shell then executes the command within that shell, buffering any generated output. The command string passed to the exec function is processed directly by the shell and special characters (vary based on shell) need to be dealt with accordingly:

external fun exec(command: String, options: ExecStringOptions): ChildProcess

external fun exec(command: String, options: ExecBufferOptions, callback: (error: ExecException?, stdout: Buffer, stderr: Buffer) -> Unit = definedExternally): ChildProcess

external fun exec(command: String, options: ExecObjectEncodingOptions?, callback: (error: ExecException?, stdout: Any, stderr: Any) -> Unit = definedExternally): ChildProcess

external fun exec(command: String, options: ExecOptions, callback: (error: ExecException?, stdout: String, stderr: String) -> Unit = definedExternally): ChildProcess

external fun exec(command: String, options: ExecStringOptions, callback: (error: ExecException?, stdout: Any, stderr: Any) -> Unit = definedExternally): ChildProcess

external fun exec(command: String, options: ExecStringOptions, callback: (error: ExecException?, stdout: String, stderr: String) -> Unit = definedExternally): ChildProcess

execFile

external fun execFile(file: String): ChildProcess

The child_process.execFile() function is similar to {@link exec} except that it does not spawn a shell by default. Rather, the specified executable file is spawned directly as a new process making it slightly more efficient than {@link exec}.

external fun execFile(file: String, args: ReadonlyArray<String>? = definedExternally): ChildProcess

external fun execFile(file: String, callback: (error: ExecFileException?, stdout: String, stderr: String) -> Unit): ChildProcess

external fun execFile(file: String, options: ExecFileObjectEncodingOptions?): ChildProcess

external fun execFile(file: String, args: ReadonlyArray<String>?, callback: (error: ExecFileException?, stdout: String, stderr: String) -> Unit): ChildProcess

external fun execFile(file: String, args: ReadonlyArray<String>?, options: ExecFileObjectEncodingOptions?): ChildProcess

external fun execFile(file: String, options: ExecFileObjectEncodingOptions?, callback: (error: ExecFileException?, stdout: Any, stderr: Any) -> Unit?): ChildProcess

external fun execFile(file: String, options: ExecFileOptions, callback: (error: ExecFileException?, stdout: String, stderr: String) -> Unit): ChildProcess

external fun execFile(file: String, options: ExecFileOptionsWithBufferEncoding, callback: (error: ExecFileException?, stdout: Buffer, stderr: Buffer) -> Unit): ChildProcess

external fun execFile(file: String, options: ExecFileOptionsWithOtherEncoding, callback: (error: ExecFileException?, stdout: Any, stderr: Any) -> Unit): ChildProcess

external fun execFile(file: String, options: ExecFileOptionsWithStringEncoding, callback: (error: ExecFileException?, stdout: String, stderr: String) -> Unit): ChildProcess

external fun execFile(file: String, args: ReadonlyArray<String>?, options: ExecFileObjectEncodingOptions?, callback: (error: ExecFileException?, stdout: Any, stderr: Any) -> Unit?): ChildProcess

external fun execFile(file: String, args: ReadonlyArray<String>?, options: ExecFileOptions, callback: (error: ExecFileException?, stdout: String, stderr: String) -> Unit): ChildProcess

external fun execFile(file: String, args: ReadonlyArray<String>?, options: ExecFileOptionsWithBufferEncoding, callback: (error: ExecFileException?, stdout: Buffer, stderr: Buffer) -> Unit): ChildProcess

external fun execFile(file: String, args: ReadonlyArray<String>?, options: ExecFileOptionsWithOtherEncoding, callback: (error: ExecFileException?, stdout: Any, stderr: Any) -> Unit): ChildProcess

external fun execFile(file: String, args: ReadonlyArray<String>?, options: ExecFileOptionsWithStringEncoding, callback: (error: ExecFileException?, stdout: String, stderr: String) -> Unit): ChildProcess

execFileSync

external fun execFileSync(file: String): Buffer

The child_process.execFileSync() method is generally identical to {@link execFile} with the exception that the method will not return until the child process has fully closed. When a timeout has been encountered and killSignal is sent, the method won't return until the process has completely exited.

external fun execFileSync(file: String, args: ReadonlyArray<String>): Buffer

external fun execFileSync(file: String, options: ExecFileSyncOptions = definedExternally): Any

external fun execFileSync(file: String, options: ExecFileSyncOptionsWithBufferEncoding): Buffer

external fun execFileSync(file: String, options: ExecFileSyncOptionsWithStringEncoding): String

external fun execFileSync(file: String, args: ReadonlyArray<String> = definedExternally, options: ExecFileSyncOptions = definedExternally): Any

external fun execFileSync(file: String, args: ReadonlyArray<String>, options: ExecFileSyncOptionsWithBufferEncoding): Buffer

external fun execFileSync(file: String, args: ReadonlyArray<String>, options: ExecFileSyncOptionsWithStringEncoding): String

execSync

external fun execSync(command: String): Buffer

The child_process.execSync() method is generally identical to {@link exec} with the exception that the method will not return until the child process has fully closed. When a timeout has been encountered and killSignal is sent, the method won't return until the process has completely exited. If the child process intercepts and handles the SIGTERM signal and doesn't exit, the parent process will wait until the child process has exited.

external fun execSync(command: String, options: ExecSyncOptions = definedExternally): Any

external fun execSync(command: String, options: ExecSyncOptionsWithBufferEncoding): Buffer

external fun execSync(command: String, options: ExecSyncOptionsWithStringEncoding): String

fork

external fun fork(modulePath: String): ChildProcess

external fun fork(modulePath: String, args: ReadonlyArray<String> = definedExternally, options: ForkOptions = definedExternally): ChildProcess

external fun fork(modulePath: URL, args: ReadonlyArray<String> = definedExternally, options: ForkOptions = definedExternally): ChildProcess

external fun fork(modulePath: URL): ChildProcess

external fun fork(modulePath: String, options: ForkOptions = definedExternally): ChildProcess

external fun fork(modulePath: URL, options: ForkOptions = definedExternally): ChildProcess

The child_process.fork() method is a special case of {@link spawn} used specifically to spawn new Node.js processes. Like {@link spawn}, a ChildProcess object is returned. The returned ChildProcess will have an additional communication channel built-in that allows messages to be passed back and forth between the parent and child. See subprocess.send() for details.

spawn

external fun spawn(command: String): ChildProcessWithoutNullStreams

external fun spawn(command: String, options: SpawnOptions): ChildProcess

external fun spawn(command: String, options: SpawnOptionsWithStdioTuple<StdioNull, StdioNull, StdioNull>): ChildProcessByStdio<Nothing?, Nothing?, Nothing?>

external fun spawn(command: String, options: SpawnOptionsWithoutStdio = definedExternally): ChildProcessWithoutNullStreams

The child_process.spawn() method spawns a new process using the given command, with command-line arguments in args. If omitted, args defaults to an empty array.

spawnSync

external fun spawnSync(command: String): SpawnSyncReturns<Buffer>

The child_process.spawnSync() method is generally identical to {@link spawn} with the exception that the function will not return until the child process has fully closed. When a timeout has been encountered and killSignal is sent, the method won't return until the process has completely exited. If the process intercepts and handles the SIGTERM signal and doesn't exit, the parent process will wait until the child process has exited.
