+/**
+ * The `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('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 `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.

+         *
+         * 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

+         * 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('child_process').fork('subprocess.js');
+         *
+         * // Open up the server object and send the handle.
+         * const server = require('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 `net` module, `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, currently 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('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('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

+     * Use `cwd` to specify the working directory from which the process is spawned.
+     * If not given, the default is to inherit the current working directory. If given,
+     * but the path does not exist, the child process emits an `ENOENT` error
+     * and exits immediately. `ENOENT` is also emitted when the command
+     * does not exist.
+     *
+     * Use `env` to specify environment variables that will be visible to the new
+     * process, the default is `process.env`.
+     *
+     * `undefined` values in `env` will be ignored.
+     *
+     * Example of running `ls -lh /usr`, capturing `stdout`, `stderr`, and the
+     * exit code:
+     *
+     * ```js
+     * const { spawn } = require('child_process');
+     * const ls = spawn('ls', ['-lh', '/usr']);
+     *

+     * ls.on('close', (code) => {
+     *   console.log(`child process exited with code ${code}`);
+     * });
+     * ```

+     * const { spawn } = require('child_process');
+     * const ps = spawn('ps', ['ax']);

+     *     console.log(`ps process exited with code ${code}`);
+     *   }
+     *   grep.stdin.end();
+     * });
+     *
+     * grep.stdout.on('data', (data) => {

+     * grep.stderr.on('data', (data) => {
+     *   console.error(`grep stderr: ${data}`);

+     *   if (code !== 0) {
+     *     console.log(`grep process exited with code ${code}`);
+     *   }
+     * });
+     * ```
+     *
+     * Example of checking for failed `spawn`:
+     *
+     * ```js
+     * const { spawn } = require('child_process');
+     * const subprocess = spawn('bad_command');
+     *
+     * subprocess.on('error', (err) => {
+     *   console.error('Failed to start subprocess.');
+     * });
+     * ```
+     *
+     * Certain platforms (macOS, Linux) will use the value of `argv[0]` for the process
+     * title while others (Windows, SunOS) will use `command`.
+     *
+     * Node.js currently overwrites `argv[0]` with `process.execPath` on startup, so`process.argv[0]` in a Node.js child process will not match the `argv0`parameter passed to `spawn` from the parent,
+     * retrieve it with the`process.argv0` property instead.
+     *
+     * If the `signal` option is enabled, calling `.abort()` on the corresponding`AbortController` is similar to calling `.kill()` on the child process except
+     * the error passed to the callback will be an `AbortError`:
+     *
+     * ```js
+     * const { spawn } = require('child_process');
+     * const controller = new AbortController();
+     * const { signal } = controller;
+     * const grep = spawn('grep', ['ssh'], { signal });
+     * grep.on('error', (err) => {
+     *   // This will be called with err being an AbortError if the controller aborts
+     * });
+     * controller.abort(); // Stops the child process
+     * ```
+     * @since v0.1.90
+     * @param command The command to run.

+     * recommended.
+     *
+     * By default, `child_process.fork()` will spawn new Node.js instances using the `process.execPath` of the parent process. The `execPath` property in the`options` object allows for an alternative
+     * execution path to be used.
+     *
+     * Node.js processes launched with a custom `execPath` will communicate with the
+     * parent process using the file descriptor (fd) identified using the
+     * environment variable `NODE_CHANNEL_FD` on the child process.
+     *
+     * Unlike the [`fork(2)`](http://man7.org/linux/man-pages/man2/fork.2.html) POSIX system call, `child_process.fork()` does not clone the
+     * current process.
+     *
+     * The `shell` option available in {@link spawn} is not supported by`child_process.fork()` and will be ignored if set.
+     *
+     * If the `signal` option is enabled, calling `.abort()` on the corresponding`AbortController` is similar to calling `.kill()` on the child process except

+ * module instead, which allows running multiple application threads within a single Node.js instance.

+ * The cluster module allows easy creation of child processes that all share
+ * server ports.
+ *
+ * ```js

+ * import http from 'node:http';
+ * import { availableParallelism } from 'node:os';
+ * import process from 'node:process';
+ *
+ * const numCPUs = availableParallelism();
+ *

+ *   console.log(`Primary ${process.pid} is running`);
+ *
+ *   // 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 {
+ *   // Workers can share any TCP connection
+ *   // In this case it is an HTTP server
+ *   http.createServer((req, res) => {

+ *   }).listen(8000);
+ *
+ *   console.log(`Worker ${process.pid} started`);
+ * }
+ * ```
+ *
+ * Running Node.js will now share port 8000 between the workers:
+ *
+ * ```console
+ * $ node server.js
+ * Primary 3596 is running
+ * Worker 4324 started
+ * Worker 4520 started
+ * Worker 6056 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`](https://nodejs.org/docs/latest-v18.x/api/process.html#processstdout) and
+ * [`process.stderr`](https://nodejs.org/docs/latest-v18.x/api/process.html#processstderr). 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`](https://nodejs.org/docs/latest-v18.x/api/process.html#a-note-on-process-io) 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 `Console` class with methods such as `console.log()`, `console.error()` and `console.warn()` that can be used to write to any Node.js stream.

+         * ```js
+         * console.log('hello world');
+         * // Prints: hello world, to stdout
