# Get the path to an executable bin file

`Bun.which` finds the absolute path of an executable file, like the `which` command on Unix-like systems.

```ts foo.ts icon="https://mintcdn.com/bun-1dd33a4e-farm-e3947f67-bump-ci-service-containers/G_XhN1oDVgnSqFyt/icons/typescript.svg?fit=max&auto=format&n=G_XhN1oDVgnSqFyt&q=85&s=81c6f421ff8ec17a56b2e6b6fac3027d" theme={"theme":{"light":"github-light","dark":"dracula"}}
Bun.which("sh"); // => "/bin/sh"
Bun.which("notfound"); // => null
Bun.which("bun"); // => "/home/user/.bun/bin/bun"
```
