# Get the path to an executable bin file

`Bun.which` is a utility function to find the absolute path of an executable file. It is similar to the `which` command in Unix-like systems.

```ts foo.ts icon="https://mintcdn.com/bun-1dd33a4e/nIz6GtMH5K-dfXeV/icons/typescript.svg?fit=max&auto=format&n=nIz6GtMH5K-dfXeV&q=85&s=5d73d76daf7eb7b158469d8c30d349b0" theme={"theme":{"light":"github-light","dark":"dracula"}}
Bun.which("sh"); // => "/bin/sh"
Bun.which("notfound"); // => null
Bun.which("bun"); // => "/home/user/.bun/bin/bun"
```
