# Parse command-line arguments

The *argument vector* is the list of arguments passed to the program when it is run. It is available as `Bun.argv`.

```ts cli.ts icon="https://mintcdn.com/bun-1dd33a4e-farm-47265618-file-slice-stream-hang/ZiIlD0efumrA_ap0/icons/typescript.svg?fit=max&auto=format&n=ZiIlD0efumrA_ap0&q=85&s=d3ea8d53d37fb8d8e83641ee2f63f641" theme={"theme":{"light":"github-light","dark":"dracula"}}
console.log(Bun.argv);
```

***

Running this file with arguments results in the following:

```sh terminal icon="terminal" theme={"theme":{"light":"github-light","dark":"dracula"}}
bun run cli.ts --flag1 --flag2 value
```

```txt theme={"theme":{"light":"github-light","dark":"dracula"}}
[ "/path/to/bun", "/path/to/cli.ts", "--flag1", "--flag2", "value" ]
```

***

To parse `argv` into a more useful format, use `util.parseArgs`.

```ts cli.ts icon="https://mintcdn.com/bun-1dd33a4e-farm-47265618-file-slice-stream-hang/ZiIlD0efumrA_ap0/icons/typescript.svg?fit=max&auto=format&n=ZiIlD0efumrA_ap0&q=85&s=d3ea8d53d37fb8d8e83641ee2f63f641" theme={"theme":{"light":"github-light","dark":"dracula"}}
import { parseArgs } from "util";

const { values, positionals } = parseArgs({
  args: Bun.argv,
  options: {
    flag1: {
      type: "boolean",
    },
    flag2: {
      type: "string",
    },
  },
  strict: true,
  allowPositionals: true,
});

console.log(values);
console.log(positionals);
```

***

Running `cli.ts` with the same arguments prints the parsed values.

```sh terminal icon="terminal" theme={"theme":{"light":"github-light","dark":"dracula"}}
bun run cli.ts --flag1 --flag2 value
```

```txt theme={"theme":{"light":"github-light","dark":"dracula"}}
[Object: null prototype] {
  flag1: true,
  flag2: "value",
}
[ "/path/to/bun", "/path/to/cli.ts" ]
```
