# Run a Shell Command

Bun Shell is a cross-platform bash-like shell built into Bun.

It runs shell commands from JavaScript and TypeScript. To get started, import the `$` function from the `bun` package.

```ts foo.ts icon="https://mintcdn.com/bun-1dd33a4e-farm-ad2450b3-transpiler-cache-version-namespa/pVrMBuZvntvIe2NO/icons/typescript.svg?fit=max&auto=format&n=pVrMBuZvntvIe2NO&q=85&s=81fcaf3ac2cead5d758f3588a492f46a" theme={"theme":{"light":"github-light","dark":"dracula"}}
import { $ } from "bun";

await $`echo Hello, world!`; // => "Hello, world!"
```

***

The `$` function is a tagged template literal that runs the command and returns a promise that resolves with the command's output.

```ts foo.ts icon="https://mintcdn.com/bun-1dd33a4e-farm-ad2450b3-transpiler-cache-version-namespa/pVrMBuZvntvIe2NO/icons/typescript.svg?fit=max&auto=format&n=pVrMBuZvntvIe2NO&q=85&s=81fcaf3ac2cead5d758f3588a492f46a" theme={"theme":{"light":"github-light","dark":"dracula"}}
import { $ } from "bun";

const output = await $`ls -l`.text();
console.log(output);
```

***

To get each line of the output as an array, use the `lines` method.

```ts foo.ts icon="https://mintcdn.com/bun-1dd33a4e-farm-ad2450b3-transpiler-cache-version-namespa/pVrMBuZvntvIe2NO/icons/typescript.svg?fit=max&auto=format&n=pVrMBuZvntvIe2NO&q=85&s=81fcaf3ac2cead5d758f3588a492f46a" theme={"theme":{"light":"github-light","dark":"dracula"}}
import { $ } from "bun";

for await (const line of $`ls -l`.lines()) {
  console.log(line);
}
```
