# 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-dc5e99a7-serve-route-target-normalization/irnPaIf5BInKUovc/icons/typescript.svg?fit=max&auto=format&n=irnPaIf5BInKUovc&q=85&s=749f5ca3fc8733d63266eddb19569000" theme={null}
console.log(Bun.argv);
```

***

Running this file with arguments results in the following:

```sh terminal icon="terminal" theme={null}
bun run cli.ts --flag1 --flag2 value
```

```txt theme={null}
[ '/path/to/bun', '/path/to/cli.ts', '--flag1', '--flag2', 'value' ]
```

***

To parse `argv` into a more useful format, `util.parseArgs` would be helpful.

Example:

```ts cli.ts icon="https://mintcdn.com/bun-1dd33a4e-farm-dc5e99a7-serve-route-target-normalization/irnPaIf5BInKUovc/icons/typescript.svg?fit=max&auto=format&n=irnPaIf5BInKUovc&q=85&s=749f5ca3fc8733d63266eddb19569000" theme={null}
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);
```

***

then it outputs

```sh terminal icon="terminal" theme={null}
bun run cli.ts --flag1 --flag2 value
```

```txt theme={null}
{
  flag1: true,
  flag2: "value",
}
[ "/path/to/bun", "/path/to/cli.ts" ]
```
