# deno-which

[![deno doc](https://jsr.io/badges/@david/which)](https://jsr.io/@david/which)

Finds the path to the specified command.

```sh

> deno add @david/which

```

```ts

import { which, whichSync } from "@david/which";

const pathToCurl = await which("curl");

```

## Custom Environment

If you want to use this with an fake or in memory environment, then you can

provide a custom environment as the second parameter.

For example:

```ts

const pathToCurl = await which("curl", {

  os: "windows",

  async fileExists(filePath: string) {

    // implement this

  },

  env(key: string) {

    // implement getting an environment variable

  },

  // optional method for requesting broader permissions for a folder

  requestPermission(folderPath: string): void {

    Deno.permissions.requestSync({

      name: "read",

      path: folderPath,

    });

  },

});

```
