+/**
+ * The `node:child_process` module provides the ability to spawn subprocesses in
+ * a manner that is similar, but not identical, to [`popen(3)`](http://man7.org/linux/man-pages/man3/popen.3.html). This capability
+ * is primarily provided by the {@link spawn} function:
+ *
+ * ```js
+ * const { spawn } = require('node:child_process');
+ * const ls = spawn('ls', ['-lh', '/usr']);
+ *
+ * ls.stdout.on('data', (data) => {
+ * console.log(`stdout: ${data}`);
+ * });
+ *
+ * ls.stderr.on('data', (data) => {
+ * console.error(`stderr: ${data}`);
+ * });
+ *
+ * ls.on('close', (code) => {
+ * console.log(`child process exited with code ${code}`);
+ * });
+ * ```
+ *
+ * By default, pipes for `stdin`, `stdout`, and `stderr` are established between
+ * the parent Node.js process and the spawned subprocess. These pipes have
+ * limited (and platform-specific) capacity. If the subprocess writes to
+ * stdout in excess of that limit without the output being captured, the
+ * subprocess blocks waiting for the pipe buffer to accept more data. This is
+ * identical to the behavior of pipes in the shell. Use the `{ stdio: 'ignore' }`option if the output will not be consumed.
+ *
+ * The command lookup is performed using the `options.env.PATH` environment
+ * variable if `env` is in the `options` object. Otherwise, `process.env.PATH` is
+ * used. If `options.env` is set without `PATH`, lookup on Unix is performed
+ * on a default search path search of `/usr/bin:/bin` (see your operating system's
+ * manual for execvpe/execvp), on Windows the current processes environment
+ * variable `PATH` is used.
+ *
+ * On Windows, environment variables are case-insensitive. Node.js
+ * lexicographically sorts the `env` keys and uses the first one that
+ * case-insensitively matches. Only first (in lexicographic order) entry will be
+ * passed to the subprocess. This might lead to issues on Windows when passing
+ * objects to the `env` option that have multiple variants of the same key, such as`PATH` and `Path`.
+ *
+ * The {@link spawn} method spawns the child process asynchronously,
+ * without blocking the Node.js event loop. The {@link spawnSync} function provides equivalent functionality in a synchronous manner that blocks
+ * the event loop until the spawned process either exits or is terminated.
+ *
+ * For convenience, the `node:child_process` module provides a handful of
+ * synchronous and asynchronous alternatives to {@link spawn} and {@link spawnSync}. Each of these alternatives are implemented on
+ * top of {@link spawn} or {@link spawnSync}.
+ *
+ * * {@link exec}: spawns a shell and runs a command within that
+ * shell, passing the `stdout` and `stderr` to a callback function when
+ * complete.
+ * * {@link execFile}: similar to {@link exec} except
+ * that it spawns the command directly without first spawning a shell by
+ * default.
+ * * {@link fork}: spawns a new Node.js process and invokes a
+ * specified module with an IPC communication channel established that allows
+ * sending messages between parent and child.
+ * * {@link execSync}: a synchronous version of {@link exec} that will block the Node.js event loop.
+ * * {@link execFileSync}: a synchronous version of {@link execFile} that will block the Node.js event loop.
+ *
+ * For certain use cases, such as automating shell scripts, the `synchronous counterparts` may be more convenient. In many cases, however,
+ * the synchronous methods can have significant impact on performance due to
+ * stalling the event loop while spawned processes complete.
+ * @see [source](https://github.com/nodejs/node/blob/v20.2.0/lib/child_process.js)

+ * // Send SIGHUP to process.

+ * ```
+ *
+ * The `ChildProcess` object may emit an `'error'` event if the signal
+ * cannot be delivered. Sending a signal to a child process that has already exited
+ * is not an error but may have unforeseen consequences. Specifically, if the
+ * process identifier (PID) has been reassigned to another process, the signal will
+ * be delivered to that process instead which can have unexpected results.
+ *
+ * While the function is called `kill`, the signal delivered to the child process
+ * may not actually terminate the process.
+ *
+ * See [`kill(2)`](http://man7.org/linux/man-pages/man2/kill.2.html) for reference.
+ *
+ * On Windows, where POSIX signals do not exist, the `signal` argument will be
+ * ignored, and the process will be killed forcefully and abruptly (similar to`'SIGKILL'`).
+ * See `Signal Events` for more details.
+ *
+ * On Linux, child processes of child processes will not be terminated
+ * when attempting to kill their parent. This is likely to happen when running a
+ * new process in a shell or with the use of the `shell` option of `ChildProcess`:
+ *
+ * ```js
+ * 'use strict';
+ * const { spawn } = require('node:child_process');
+ *
+ * const subprocess = spawn(
+ * 'sh',
+ * [
+ * '-c',
+ * `node -e "setInterval(() => {

+ * }, 500);"`,
+ * ], {
+ * stdio: ['inherit', 'inherit', 'inherit'],
+ * },
+ * );
+ *
+ * setTimeout(() => {
+ * subprocess.kill(); // Does not terminate the Node.js process in the shell.
+ * }, 2000);
+ * ```

+ /**
+ * When an IPC channel has been established between the parent and child (
+ * i.e. when using {@link fork}), the `subprocess.send()` method can
+ * be used to send messages to the child process. When the child process is a
+ * Node.js instance, these messages can be received via the `'message'` event.
+ *
+ * The message goes through serialization and parsing. The resulting
+ * message might not be the same as what is originally sent.
+ *
+ * For example, in the parent script:
+ *
+ * ```js
+ * const cp = require('node:child_process');
+ * const n = cp.fork(`${__dirname}/sub.js`);
+ *
+ * n.on('message', (m) => {
+ * console.log('PARENT got message:', m);
+ * });
+ *
+ * // Causes the child to print: CHILD got message: { hello: 'world' }
+ * n.send({ hello: 'world' });
+ * ```
+ *
+ * And then the child script, `'sub.js'` might look like this:
+ *
+ * ```js
+ * process.on('message', (m) => {
+ * console.log('CHILD got message:', m);
+ * });
+ *
+ * // Causes the parent to print: PARENT got message: { foo: 'bar', baz: null }
+ * process.send({ foo: 'bar', baz: NaN });
+ * ```
+ *
+ * Child Node.js processes will have a `process.send()` method of their own
+ * that allows the child to send messages back to the parent.
+ *
+ * There is a special case when sending a `{cmd: 'NODE_foo'}` message. Messages
+ * containing a `NODE_` prefix in the `cmd` property are reserved for use within
+ * Node.js core and will not be emitted in the child's `'message'` event. Rather, such messages are emitted using the`'internalMessage'` event and are consumed internally by Node.js.
+ * Applications should avoid using such messages or listening for`'internalMessage'` events as it is subject to change without notice.
+ *
+ * The optional `sendHandle` argument that may be passed to `subprocess.send()` is
+ * for passing a TCP server or socket object to the child process. The child will
+ * receive the object as the second argument passed to the callback function
+ * registered on the `'message'` event. Any data that is received
+ * and buffered in the socket will not be sent to the child.
+ *
+ * The optional `callback` is a function that is invoked after the message is
+ * sent but before the child may have received it. The function is called with a
+ * single argument: `null` on success, or an `Error` object on failure.
+ *
+ * If no `callback` function is provided and the message cannot be sent, an`'error'` event will be emitted by the `ChildProcess` object. This can
+ * happen, for instance, when the child process has already exited.
+ *
+ * `subprocess.send()` will return `false` if the channel has closed or when the
+ * backlog of unsent messages exceeds a threshold that makes it unwise to send
+ * more. Otherwise, the method returns `true`. The `callback` function can be
+ * used to implement flow control.
+ *
+ * #### Example: sending a server object
+ *
+ * The `sendHandle` argument can be used, for instance, to pass the handle of
+ * a TCP server object to the child process as illustrated in the example below:
+ *
+ * ```js
+ * const subprocess = require('node:child_process').fork('subprocess.js');
+ *
+ * // Open up the server object and send the handle.
+ * const server = require('node:net').createServer();
+ * server.on('connection', (socket) => {
+ * socket.end('handled by parent');
+ * });
+ * server.listen(1337, () => {
+ * subprocess.send('server', server);
+ * });
+ * ```
+ *
+ * The child would then receive the server object as:
+ *
+ * ```js
+ * process.on('message', (m, server) => {
+ * if (m === 'server') {
+ * server.on('connection', (socket) => {
+ * socket.end('handled by child');
+ * });
+ * }
+ * });
+ * ```
+ *
+ * Once the server is now shared between the parent and child, some connections
+ * can be handled by the parent and some by the child.
+ *
+ * While the example above uses a server created using the `node:net` module,`node:dgram` module servers use exactly the same workflow with the exceptions of
+ * listening on a `'message'` event instead of `'connection'` and using`server.bind()` instead of `server.listen()`. This is, however, only
+ * supported on Unix platforms.
+ *
+ * #### Example: sending a socket object
+ *
+ * Similarly, the `sendHandler` argument can be used to pass the handle of a
+ * socket to the child process. The example below spawns two children that each
+ * handle connections with "normal" or "special" priority:
+ *
+ * ```js
+ * const { fork } = require('node:child_process');
+ * const normal = fork('subprocess.js', ['normal']);
+ * const special = fork('subprocess.js', ['special']);
+ *
+ * // Open up the server and send sockets to child. Use pauseOnConnect to prevent
+ * // the sockets from being read before they are sent to the child process.
+ * const server = require('node:net').createServer({ pauseOnConnect: true });
+ * server.on('connection', (socket) => {
+ *
+ * // If this is special priority...
+ * if (socket.remoteAddress === '74.125.127.100') {
+ * special.send('socket', socket);
+ * return;
+ * }
+ * // This is normal priority.
+ * normal.send('socket', socket);
+ * });
+ * server.listen(1337);
+ * ```
+ *
+ * The `subprocess.js` would receive the socket handle as the second argument
+ * passed to the event callback function:
+ *
+ * ```js
+ * process.on('message', (m, socket) => {
+ * if (m === 'socket') {
+ * if (socket) {
+ * // Check that the client socket exists.
+ * // It is possible for the socket to be closed between the time it is
+ * // sent and the time it is received in the child process.
+ * socket.end(`Request handled with ${process.argv[2]} priority`);
+ * }
+ * }
+ * });
+ * ```
+ *
+ * Do not use `.maxConnections` on a socket that has been passed to a subprocess.
+ * The parent cannot track when the socket is destroyed.
+ *
+ * Any `'message'` handlers in the subprocess should verify that `socket` exists,
+ * as the connection may have been closed during the time it takes to send the
+ * connection to the child.
+ * @since v0.5.9

+ *
+ * // Fork workers.
+ * for (let i = 0; i < numCPUs; i++) {
+ * cluster.fork();
+ * }
+ *
+ * cluster.on('exit', (worker, code, signal) => {
+ * console.log(`worker ${worker.process.pid} died`);
+ * });
+ * } else {

+ * Primary 3596 is running
+ * Worker 4324 started
+ * Worker 4520 started

+/**
+ * The `node:console` module provides a simple debugging console that is similar to
+ * the JavaScript console mechanism provided by web browsers.
+ *
+ * The module exports two specific components:
+ *
+ * * A `Console` class with methods such as `console.log()`, `console.error()`, and`console.warn()` that can be used to write to any Node.js stream.
+ * * A global `console` instance configured to write to `process.stdout` and `process.stderr`. The global `console` can be used without calling`require('node:console')`.
+ *
+ * _**Warning**_: The global console object's methods are neither consistently
+ * synchronous like the browser APIs they resemble, nor are they consistently
+ * asynchronous like all other Node.js streams. See the `note on process I/O` for
+ * more information.
+ *
+ * Example using the global `console`:
+ *
+ * ```js
+ * console.log('hello world');
+ * // Prints: hello world, to stdout
+ * console.log('hello %s', 'world');
+ * // Prints: hello world, to stdout
+ * console.error(new Error('Whoops, something bad happened'));
+ * // Prints error message and stack trace to stderr:
+ * // Error: Whoops, something bad happened
+ * // at [eval]:5:15
+ * // at Script.runInThisContext (node:vm:132:18)
+ * // at Object.runInThisContext (node:vm:309:38)
+ * // at node:internal/process/execution:77:19
+ * // at [eval]-wrapper:6:22
+ * // at evalScript (node:internal/process/execution:76:60)
+ * // at node:internal/main/eval_string:23:3
+ *
+ * const name = 'Will Robinson';
+ * console.warn(`Danger ${name}! Danger!`);
+ * // Prints: Danger Will Robinson! Danger!, to stderr
+ * ```
+ *
+ * Example using the `Console` class:
+ *
+ * ```js
+ * const out = getStreamSomehow();
+ * const err = getStreamSomehow();
+ * const myConsole = new console.Console(out, err);
+ *
+ * myConsole.log('hello world');
+ * // Prints: hello world, to out
+ * myConsole.log('hello %s', 'world');
+ * // Prints: hello world, to out
+ * myConsole.error(new Error('Whoops, something bad happened'));
+ * // Prints: [Error: Whoops, something bad happened], to err
+ *
+ * const name = 'Will Robinson';
+ * myConsole.warn(`Danger ${name}! Danger!`);

+ * * A global `console` instance configured to write to `process.stdout` and `process.stderr`. The global `console` can be used without calling`require('console')`.
+ *
+ * _**Warning**_: The global console object's methods are neither consistently
+ * synchronous like the browser APIs they resemble, nor are they consistently
+ * asynchronous like all other Node.js streams. See the `note on process I/O` for
+ * more information.
+ *
+ * Example using the global `console`:
+ *
+ * ```js
+ * console.log('hello world');
+ * // Prints: hello world, to stdout
+ * console.log('hello %s', 'world');
+ * // Prints: hello world, to stdout
+ * console.error(new Error('Whoops, something bad happened'));

+ * // at [eval]:5:15
+ * // at Script.runInThisContext (node:vm:132:18)
+ * // at Object.runInThisContext (node:vm:309:38)

+ * // at node:internal/main/eval_string:23:3
+ *
+ * const name = 'Will Robinson';
+ * console.warn(`Danger ${name}! Danger!`);

+ * ```
+ *
+ * Example using the `Console` class:

+ * const err = getStreamSomehow();
+ * const myConsole = new console.Console(out, err);
+ *
+ * myConsole.log('hello world');
