 dv.setUint16(1, 513);
-// [0x11, 0x10, 0x1, 0x0]

+```ts
+import { readdir } from "node:fs/promises";
+
+// read all the files in the current directory
+const files = await readdir(import.meta.dir);
+```
+
+#### Reading directories recursively
+
+To recursively read a directory in Bun, use `readdir` with `recursive: true`.
+
+```ts
+import { readdir } from "node:fs/promises";
+
+// read all the files in the current directory, recursively
+const files = await readdir("../", { recursive: true });
+```
+
+### Creating directories (mkdir)
+
+To recursively create a directory, use `mkdir` in `node:fs`:

+```ts

+
+```ts

 **Note** — Currently, the `--compile` flag can only accept a single entrypoint at a time and does not support the following flags:

-- `--external`

 {% /callout %}
 
+## Deploying to production
+
+Compiled executables reduce memory usage and improve Bun's start time.
+
+Normally, Bun reads and transpiles JavaScript and TypeScript files on `import` and `require`. This is part of what makes so much of Bun "just work", but it's not free. It costs time and memory to read files from disk, resolve file paths, parse, transpile, and print source code. 
+
+With compiled executables, you can move that cost from runtime to build-time.
+
+When deploying to production, we recommend the following:
+
+```sh
+bun build --compile --minify --sourcemap ./path/to/my/app.ts --outfile myapp
+```
+
+**What do these flags do?**
+
+The `--minify` argument optimizes the size of the transpiled output code. If you have a large application, this can save megabytes of space. For smaller applications, it might still improve start time a little.
+
+The `--sourcemap` argument embeds a sourcemap compressed with zstd, so that errors & stacktraces point to their original locations instead of the transpiled location. Bun will automatically decompress & resolve the sourcemap when an error occurs.
+
+## SQLite
+
+You can use `bun:sqlite` imports with `bun build --compile`.
+
+By default, the database is resolved relative to the current working directory of the process.
+
+```js
+import db from './my.db' with {type: "sqlite"};
+
+console.log(db.query("select * from users LIMIT 1").get());
+```
+
+That means if the executable is located at `/usr/bin/hello`, the user's terminal is located at `/home/me/Desktop`, it will look for `/home/me/Desktop/my.db`.
+
+```
+$ cd /home/me/Desktop
+$ ./hello

+
+console.log(myEmbeddedDb.query("select * from users LIMIT 1").get());
+```
+
+This database is read-write, but all changes are lost when the executable exits (since it's stored in memory).
+
+### Embedding N-API Addons
+
+As of Bun v1.0.23, you can embed `.node` files into executables.
+
+```js
+const addon = require("./addon.node");
+
+console.log(addon.hello());
+```
+
+Unfortunately, if you're using `@mapbox/node-pre-gyp` or other similar tools, you'll need to make sure the `.node` file is directly required or it won't bundle correctly.

 ## Minification
 
 To trim down the size of the executable a little, pass `--minify` to `bun build --compile`. This uses Bun's minifier to reduce the code size. Overall though, Bun's binary is still way too big and we need to make it smaller.

-Bundling is currently an important mechanism for building complex web apps.
-
-Modern apps typically consist of a large number of files and package dependencies. Despite the fact that modern browsers support [ES Module](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Modules) imports, it's still too slow to fetch each file via individual HTTP requests. _Bundling_ is the process of concatenating several source files into a single large file that can be loaded in a single request.
-
-{% callout %}
-**On bundling** — Despite recent advances like [`modulepreload`](https://developer.mozilla.org/en-US/docs/Web/HTML/Attributes/rel/modulepreload) and [HTTP/3](https://en.wikipedia.org/wiki/HTTP/3), bundling is still the most performant approach.
-{% /callout %}
-
-## Bundling your app
-
-Bun's approach to bundling is a little different from other bundlers. Start by passing your app's entrypoint to `bun bun`.
-
-```bash
-$ bun bun ./app.js
-```
-
-Your entrypoint can be any `js|jsx|ts|tsx|html` file. With this file as a starting point, Bun will construct a graph of imported files and packages, transpile everything, and generate a file called `node_modules.bun`.
-
-## What is `.bun`?
-
-{% callout %}
-**Note** — [This format may change soon](https://github.com/oven-sh/bun/issues/121)
-{% /callout %}
-
-A `.bun` file contains the pre-transpiled source code of your application, plus a bunch of binary-encoded metadata about your application's structure. as a contains:
-
-- all the bundled source code
-- all the bundled source code metadata
-- project metadata & configuration
-
-Here are some of the questions `.bun` files answer:
-
-- when I import `react/index.js`, where in the `.bun` is the code for that? (not resolving, just the code)
-- what modules of a package are used?
-- what framework is used? (e.g., Next.js)
-- where is the routes directory?
-- how big is each imported dependency?
-- what is the hash of the bundle’s contents? (for etags)
-- what is the name & version of every npm package exported in this bundle?
-- what modules from which packages are used in this project? ("project" is defined as all the entry points used to generate the .bun)
-
-All in one file.
-
-It’s a little like a build cache, but designed for reuse across builds.
-
-{% details summary="Position-independent code" %}
-
-From a design perspective, the most important part of the `.bun` format is how code is organized. Each module is exported by a hash like this:
-
-```js
-// preact/dist/preact.module.js
-export var $eb6819b = $$m({
-  "preact/dist/preact.module.js": (module, exports) => {
-    let n, l, u, i, t, o, r, f, e = {}, c = [], s = /acit|ex(?:s|g|n|p|$)|rph|grid|ows|mnc|ntw|ine[ch]|zoo|^ord|itera/i;
-    // ... rest of code
-```
-
-This makes bundled modules [position-independent](https://en.wikipedia.org/wiki/Position-independent_code). In theory, one could import only the exact modules in-use without reparsing code and without generating a new bundle. One bundle can dynamically become many bundles comprising only the modules in use on the webpage. Thanks to the metadata with the byte offsets, a web server can send each module to browsers [zero-copy](https://en.wikipedia.org/wiki/Zero-copy) using [sendfile](https://man7.org/linux/man-pages/man2/sendfile.2.html). Bun itself is not quite this smart yet, but these optimizations would be useful in production and potentially very useful for React Server Components.
-
-To see the schema inside, have a look at [`JavascriptBundleContainer`](./src/api/schema.d.ts#:~:text=export%20interface-,JavascriptBundleContainer,-%7B). You can find JavaScript bindings to read the metadata in [src/api/schema.js](./src/api/schema.js). This is not really an API yet. It’s missing the part where it gets the binary data from the bottom of the file. Someday, I want this to be usable by other tools too.
-{% /details %}
-
-## Where is the code?
-
-`.bun` files are marked as executable.
-
-To print out the code, run `./node_modules.bun` in your terminal or run `bun ./path-to-node_modules.bun`.
-
-Here is a copy-pastable example:
-
-```bash
-$ ./node_modules.bun > node_modules.js
-```
-
-This works because every `.bun` file starts with this:
-
-```
-#!/usr/bin/env bun
-```
-
-To deploy to production with Bun, you’ll want to get the code from the `.bun` file and stick that somewhere your web server can find it (or if you’re using Vercel or a Rails app, in a `public` folder).
-
-Note that `.bun` is a binary file format, so just opening it in VSCode or vim might render strangely.
-
-## Advanced
-
-By default, `bun bun` only bundles external dependencies that are `import`ed or `require`d in either app code or another external dependency. An "external dependency" is defined as, "A JavaScript-like file that has `/node_modules/` in the resolved file path and a corresponding `package.json`".
-
-To force Bun to bundle packages which are not located in a `node_modules` folder (i.e., the final, resolved path following all symlinks), add a `bun` section to the root project’s `package.json` with `alwaysBundle` set to an array of package names to always bundle. Here’s an example:
-
-```json
-{
-  "name": "my-package-name-in-here",
-  "bun": {
-    "alwaysBundle": ["@mybigcompany/my-workspace-package"]
-  }
-}
-```
-
-Bundled dependencies are not eligible for Hot Module Reloading. The code is served to browsers & Bun.js verbatim. But, in the future, it may be sectioned off into only parts of the bundle being used. That’s possible in the current version of the `.bun` file (so long as you know which files are necessary), but it’s not implemented yet. Longer-term, it will include all `import` and `export` of each module inside.
-
-## What is the module ID hash?
-
-The `$eb6819b` hash used here:
-
-```js
-export var $eb6819b = $$m({
-```
-
-Is generated like this:
-
-1. Murmur3 32-bit hash of `package.name@package.version`. This is the hash uniquely identifying the npm package.
-2. Wyhash 64 of the `package.hash` + `package_path`. `package_path` means "relative to the root of the npm package, where is the module imported?". For example, if you imported `react/jsx-dev-runtime.js`, the `package_path` is `jsx-dev-runtime.js`. `react-dom/cjs/react-dom.development.js` would be `cjs/react-dom.development.js`
-3. Truncate the hash generated above to a `u32`
-
-The implementation details of this module ID hash will vary between versions of Bun. The important part is the metadata contains the module IDs, the package paths, and the package hashes, so it shouldn’t really matter in practice if other tooling wants to make use of any of this.

-### Zig
-
-Bun pins a version of Zig. As the compiler is still in development, breaking changes happen often that will break the build. It is recommended to use [Zigup](https://github.com/marler8997/zigup/releases) as it can quickly switch to any version by name, but you can also [manually download Zig](https://ziglang.org/download/).

-```bash

-
 {% callout %}
-We last updated Zig on **October 26th, 2023**
+It is not recommended to install `ninja` / `cmake` into your global path, because you may run into a situation where you try to build bun without .\scripts\env.ps1 sourced.
 {% /callout %}
 
-### Codegen
-
-On Unix platforms, we depend on an existing build of Bun to generate code for itself. Since the Windows build is not stable enough for this to run the code generators, you currently need to use another computer or WSL to generate this:
-
-```bash
-$ wsl --install # run twice if it doesnt install
-# in the linux environment
-$ sudo apt install unzip
-$ curl -fsSL https://bun.sh/install | bash
-```
-
-Whenever codegen-related things are updated, please re-run
-
-```ps1
-$ .\scripts\codegen.ps1
-```
-
 ## Building
 
 ```ps1
-npm install
+bun install
 
 .\scripts\env.ps1
-.\scripts\update-submodules.ps1
-.\scripts\all-dependencies.ps1
-.\scripts\codegen.ps1
+.\scripts\update-submodules.ps1 # this syncs git submodule state
+.\scripts\all-dependencies.ps1 # this builds all dependencies
+.\scripts\make-old-js.ps1 # runs some old code generators
 
-cd build # this was created by the codegen.ps1 script in the prerequisites
+# Configure build environment
+cmake -Bbuild -GNinja -DCMAKE_BUILD_TYPE=Debug
 
-cmake .. -G Ninja -DCMAKE_BUILD_TYPE=Debug
-ninja
+# Build bun
+ninja -Cbuild
 ```
 
 If this was successful, you should have a `bun-debug.exe` in the `build` folder.
 
 ```ps1
-.\bun-debug.exe --version
+.\build\bun-debug.exe --revision
+```
+
+You should add this to `$Env:PATH`. The simplest way to do so is to open the start menu, type "Path", and then navigate the environment variables menu to add `C:\.....\bun\build` to the user environment variable `PATH`. You should then restart your editor (if it does not update still, log out and log back in).
+
+## Extra paths
+
+- WebKit is extracted to `build/bun-webkit`
+- Zig is extracted to `.cache/zig/zig.exe`
+
+## Tests
+
+You can run the test suite either using `bun test`, or by using the wrapper script `packages\bun-internal-test`. The internal test package is a wrapper cli to run every test file in a separate instance of bun.exe, to prevent a crash in the test runner from stopping the entire suite.
+
+```ps1
+# Setup
+bun i --cwd packages\bun-internal-test
+
+# Run the entire test suite with reporter
+# the package.json script "test" uses "build/bun-debug.exe" by default
+bun run test
+
+# Run an individual test file:
+bun-debug test node\fs
+bun-debug test "C:\bun\test\js\bun\resolve\import-meta.test.js"

+## `bun run`
+
+The `bun run` command can be configured under the `[run]` section. These apply to the `bun run` command and the `bun` command when running a file or executable or script.
+
+Currently, `bunfig.toml` isn't always automatically loaded for `bun run` in a local project (it does check for a global `bunfig.toml`), so you might still need to pass `-c` or `-c=bunfig.toml` to use these settings.
+
+### `run.shell` - use the system shell or Bun's shell
+
+The shell to use when running package.json scripts via `bun run` or `bun`. On Windows, this defaults to `"bun"` and on other platforms it defaults to `"system"`.
+
+To always use the system shell instead of Bun's shell (default behavior unless Windows):
+
+```toml
+[run]
+# default outside of Windows
+shell = "system"
+```
+
+To always use Bun's shell instead of the system shell:
+
+```toml
+[run]
+# default on Windows
+shell = "bun"
+```
+
+### `run.bun` - auto alias `node` to `bun`
+
+When `true`, this prepends `$PATH` with a `node` symlink that points to the `bun` binary for all scripts or executables invoked by `bun run` or `bun`.
+
+This means that if you have a script that runs `node`, it will actually run `bun` instead, without needing to change your script. This works recursively, so if your script runs another script that runs `node`, it will also run `bun` instead. This applies to shebangs as well, so if you have a script with a shebang that points to `node`, it will actually run `bun` instead.
+
+By default, this is enabled if `node` is not already in your `$PATH`.
+
+```toml
+[run]
+# equivalent to `bun --bun` for all `bun run` commands
+bun = true
+```
+
+You can test this by running:
+
+```sh
+$ bun --bun which node # /path/to/bun
+$ bun which node # /path/to/node
+```
+
+This option is equivalent to prefixing all `bun run` commands with `--bun`:
+
+```sh
+bun --bun run dev
+bun --bun dev
+bun run --bun dev
+```
+
+If set to `false`, this will disable the `node` symlink.
+
+### `run.silent` - suppress reporting the command being run
+
+When `true`, suppresses the output of the command being run by `bun run` or `bun`.
+
+```toml
+[run]
+silent = true
+```
+
+Without this option, the command being run will be printed to the console:
+
+```sh
+$ bun run dev
+> $ echo "Running \"dev\"..."
+Running "dev"...
+```
+
+With this option, the command being run will not be printed to the console:
+
+```sh
+$ bun run dev
+Running "dev"...
+```
+
+This is equivalent to passing `--silent` to all `bun run` commands:
+
+```sh
+bun --silent run dev
+bun --silent dev
+bun run --silent dev
+```

+Bun Shell makes shell scripting with JavaScript & TypeScript fun. It's a cross-platform bash-like shell with seamless JavaScript interop.
+
+{% callout type="note" %}
+**Alpha-quality software**: Bun Shell is an unstable API still under development. If you have feature requests or run into bugs, please open an issue. There may be breaking changes in the future.
+{% /callout %}
+
+Quickstart:
+
+```js
+import { $ } from "bun";
+
+const response = await fetch("https://example.com");
+
+// Use Response as stdin.
+await $`cat < ${response} | wc -c`; // 1256
+```
+
+## Features:
+
+- **Cross-platform**: works on Windows, Linux & macOS. Instead of `rimraf` or `cross-env`', you can use Bun Shell without installing extra dependencies. Common shell commands like `ls`, `cd`, `rm` are implemented natively.
+- **Familiar**: Bun Shell is a bash-like shell, supporting redirection, pipes, environment variables and more.
+- **Globs**: Glob patterns are supported natively, including `**`, `*`, `{expansion}`, and more.
+- **Template literals**: Template literals are used to execute shell commands. This allows for easy interpolation of variables and expressions.
+- **Safety**: Bun Shell escapes all strings by default, preventing shell injection attacks.
+- **JavaScript interop**: Use `Response`, `ArrayBuffer`, `Blob`, `Bun.file(path)` and other JavaScript objects as stdin, stdout, and stderr.
+
+## Getting started
+
+The simplest shell command is `echo`. To run it, use the `$` template literal tag:
+
+```js
+import { $ } from "bun";
+
+await $`echo "Hello World!"`; // Hello World!
+```
+
+By default, shell commands print to stdout. To quiet the output, call `.quiet()`:
+
+```js
+import { $ } from "bun";
+
+await $`echo "Hello World!"`.quiet(); // No output
+```
+
+What if you want to access the output of the command as text? Use `.text()`:
+
+```js
+import { $ } from "bun";
+
+// .text() automatically calls .quiet() for you
+const welcome = await $`echo "Hello World!"`.text();
+
+console.log(welcome); // Hello World!\n
+```
+
+To get stdout, stderr, and the exit code, use await or `.run`:
+
+```js
+import { $ } from "bun";
+
+const { stdout, stderr, exitCode } = await $`echo "Hello World!"`.quiet();
+
+console.log(stdout); // Buffer(6) [ 72, 101, 108, 108, 111, 32 ]
+console.log(stderr); // Buffer(0) []
+console.log(exitCode); // 0
+```
+
+## Redirection
+
+A command's _input_ or _output_ may be _redirected_ using the typical Bash operators:
+
+- `<` redirect stdin
+- `>` or `1>` redirect stdout
+- `2>` redirect stderr
+- `&>` redirect both stdout and stderr
+- `>>` or `1>>` redirect stdout, _appending_ to the destination, instead of overwriting
+- `2>>` redirect stderr, _appending_ to the destination, instead of overwriting
+- `&>>` redirect both stdout and stderr, _appending_ to the destination, instead of overwriting
+- `1>&2` redirect stdout to stderr (all writes to stdout will instead be in stderr)
+- `2>&1` redirect stderr to stdout (all writes to stderr will instead be in stdout)
+
+Bun Shell also supports redirecting from and to JavaScript objects.
+
+### Example: Redirect output to JavaScript objects (`>`)
+
+To redirect stdout to a JavaScript object, use the `>` operator:
+
+```js
+import { $ } from "bun";
+
+const buffer = Buffer.alloc(100);
+const result = await $`echo "Hello World!" > ${buffer}`;
+
+console.log(result.exitCode); // 0
+console.log(buffer.toString()); // Hello World!\n
+```
+
+The following JavaScript objects are supported for redirection to:
+
+- `Buffer`, `Uint8Array`, `Uint16Array`, `Uint32Array`, `Int8Array`, `Int16Array`, `Int32Array`, `Float32Array`, `Float64Array`, `ArrayBuffer`, `SharedArrayBuffer` (writes to the underlying buffer)
+- `Bun.file(path)`, `Bun.file(fd)` (writes to the file)
+
+### Example: Redirect input from JavaScript objects (`<`)
+
+To redirect the output from JavaScript objects to stdin, use the `<` operator:
+
+```js
+import { $, file } from "bun";
+
+const response = new Response("hello i am a response body");
+
+const result = await $`cat < ${response}`.text();
+
+console.log(result); // hello i am a response body
+```
+
+The following JavaScript objects are supported for redirection from:
+
+- `Buffer`, `Uint8Array`, `Uint16Array`, `Uint32Array`, `Int8Array`, `Int16Array`, `Int32Array`, `Float32Array`, `Float64Array`, `ArrayBuffer`, `SharedArrayBuffer` (reads from the underlying buffer)
+- `Bun.file(path)`, `Bun.file(fd)` (reads from the file)
+- `Response` (reads from the body)
+
+### Example: Redirect stdin -> file
+
+```js
+import { $ } from "bun";
+
+await $`cat < myfile.txt`;
+```
+
+### Example: Redirect stdout -> file
+
+```js
+import { $ } from "bun";
+
+await $`echo bun! > greeting.txt`;
+```
+
+### Example: Redirect stderr -> file
+
+```js
+import { $ } from "bun";
+
+await $`bun run index.ts 2> errors.txt`;
+```
+
+### Example: Redirect stdout -> stderr
+
+```js
+import { $ } from "bun";
+
+// redirects stderr to stdout, so all output
+// will be available on stdout
+await $`bun run ./index.ts 2>&1`;
+```
+
+### Example: Redirect stderr -> stdout
+
+```js
+import { $ } from "bun";
+
+// redirects stdout to stderr, so all output
+// will be available on stderr
+await $`bun run ./index.ts 1>&2`;
+```
+
+## Piping (`|`)
+
+Like in bash, you can pipe the output of one command to another:
+
+```js
+import { $ } from "bun";
+
+const result = await $`echo "Hello World!" | wc -w`.text();
+
+console.log(result); // 2\n
+```
+
+You can also pipe with JavaScript objects:
+
+```js
+import { $ } from "bun";
+
+const response = new Response("hello i am a response body");
+
+const result = await $`cat < ${response} | wc -w`.text();
+
+console.log(result); // 6\n
+```
+
+## Environment variables
+
+Environment variables can be set like in bash:
+
+```js
+import { $ } from "bun";
+
+await $`FOO=foo bun -e 'console.log(process.env.FOO)'`; // foo\n
+```
+
+You can use string interpolation to set environment variables:
+
+```js
+import { $ } from "bun";
+
+const foo = "bar123";
+
+await $`FOO=${foo + "456"} bun -e 'console.log(process.env.FOO)'`; // bar123456\n
+```
+
+Input is escaped by default, preventing shell injection attacks:
+
+```js
+import { $ } from "bun";
+
+const foo = "bar123; rm -rf /tmp";
+
+await $`FOO=${foo} bun -e 'console.log(process.env.FOO)'`; // bar123; rm -rf /tmp\n
+```
+
+### Changing the environment variables
+
+By default, `process.env` is used as the environment variables for all commands.
+
+You can change the environment variables for a single command by calling `.env()`:
+
+```js
+import { $ } from "bun";
+
+await $`echo $FOO`.env({ ...process.env, FOO: "bar" }); // bar
+```
+
+You can change the default environment variables for all commands by calling `$.env`:
+
+```js
+import { $ } from "bun";
+
+$.env({ FOO: "bar" });
+
+// the globally-set $FOO
+await $`echo $FOO`; // bar
+
+// the locally-set $FOO
+await $`echo $FOO`.env({ FOO: "baz" }); // baz
+```
+
+You can reset the environment variables to the default by calling `$.env()` with no arguments:
+
+```js
+import { $ } from "bun";
+
+$.env({ FOO: "bar" });
+
+// the globally-set $FOO
+await $`echo $FOO`; // bar
+
+// the locally-set $FOO
+await $`echo $FOO`.env(undefined); // ""
+```
+
+### Changing the working directory
+
+You can change the working directory of a command by passing a string to `.cwd()`:
+
+```js
+import { $ } from "bun";
+
+await $`pwd`.cwd("/tmp"); // /tmp
+```
+
+You can change the default working directory for all commands by calling `$.cwd`:
+
+```js
+import { $ } from "bun";
+
+$.cwd("/tmp");
+
+// the globally-set working directory
+await $`pwd`; // /tmp
+
+// the locally-set working directory
+await $`pwd`.cwd("/"); // /
+```
+
+## Reading output
+
+To read the output of a command as a string, use `.text()`:
+
+```js
+import { $ } from "bun";
+
+const result = await $`echo "Hello World!"`.text();
+
+console.log(result); // Hello World!\n
+```
+
+### Reading output as JSON
+
+To read the output of a command as JSON, use `.json()`:
+
+```js
+import { $ } from "bun";
+
+const result = await $`echo '{"foo": "bar"}'`.json();
+
+console.log(result); // { foo: "bar" }
+```
+
+### Reading output line-by-line
+
+To read the output of a command line-by-line, use `.lines()`:
+
+```js
+import { $ } from "bun";
+
+for await (let line of $`echo "Hello World!"`.lines()) {
+  console.log(line); // Hello World!
+}
+```
+
+You can also use `.lines()` on a completed command:
+
+```js
+import { $ } from "bun";
+
+const search = "bun";
+
+for await (let line of $`cat list.txt | grep ${search}`.lines()) {
+  console.log(line);
+}
+```
+
+### Reading output as a Blob
+
+To read the output of a command as a Blob, use `.blob()`:
+
+```js
+import { $ } from "bun";
+
+const result = await $`echo "Hello World!"`.blob();
+
+console.log(result); // Blob(13) { size: 13, type: "text/plain" }
+```
+
+## Builtin Commands
+
+For cross-platform compatibility, Bun Shell implements a set of builtin commands, in addition to reading commands from the PATH environment variable.
+
+- `cd`: change the working directory
+- `ls`: list files in a directory
+- `rm`: remove files and directories
+- `echo`: print text
+- `pwd`: print the working directory
+- `bun`: run bun in bun
+
+**Partially** implemented:
+
+- `mv`: move files and directories (missing cross-device support)
+
+**Not** implemented yet, but planned:
+
+- `mkdir`: create directories
+- `cp`: copy files and directories
+- `cat`: concatenate files
+
+## Utilities
+
+Bun Shell also implements a set of utilities for working with shells.
+
+### `$.braces` (brace expansion)
+
+This function implements simple [brace expansion](https://www.gnu.org/software/bash/manual/html_node/Brace-Expansion.html) for shell commands:
+
+```js
+import { $ } from "bun";
+
+await $.braces(`echo {1,2,3}`);
+// => ["echo 1", "echo 2", "echo 3"]
+```
+
+### `$.escape` (escape strings)
+
+Exposes Bun Shell's escaping logic as a function:
+
+```js
+import { $ } from "bun";
+
+console.log($.escape('$(foo) `bar` "baz"'));
+// => \$(foo) \`bar\` \"baz\"
+```
+
+If you do not want your string to be escaped, wrap it in a `{ raw: 'str' }` object:
+
+```js
+import { $ } from "bun";
+
+await $`echo ${{ raw: '$(foo) `bar` "baz"' }}`;
+// => bun: command not found: foo
+// => bun: command not found: bar
+// => baz
+```
+
+## .sh file loader
+
+For simple shell scripts, instead of `/bin/sh`, you can use Bun Shell to run shell scripts.
+
+To do so, just run the script with `bun` on a file with the `.bun.sh` extension.
+
+```sh#script.bun.sh
+echo "Hello World! pwd=$(pwd)"
+```
+
+```sh
+$ bun ./script.bun.sh
+Hello World! pwd=/home/demo
+```
+
+Scripts with Bun Shell are cross platform, which means they work on Windows:
+
+```
+PS C:\Users\Demo> bun .\script.bun.sh
+Hello World! pwd=C:\Users\Demo
+```
