//// tab | Linux, macOS

```plaintext
/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin
```

Isso significa que o sistema deve procurar programas nos diretórios:

* `/usr/local/bin`
* `/usr/bin`
* `/bin`
* `/usr/sbin`
* `/sbin`

////

//// tab | Windows

```plaintext
C:\Program Files\Python312\Scripts;C:\Program Files\Python312;C:\Windows\System32

예를 들어, `PATH` 환경 변수는 다음과 같습니다:

//// tab | Linux, macOS

```plaintext
/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin
```

이는 시스템이 다음 디렉토리에서 프로그램을 찾아야 함을 의미합니다:

-   `/usr/local/bin`
-   `/usr/bin`
-   `/bin`
-   `/usr/sbin`
-   `/sbin`

////

//// tab | Windows

```plaintext
C:\Program Files\Python312\Scripts;C:\Program Files\Python312;C:\Windows\System32
```

```plaintext
/home/user/code/awesome-project/.venv/bin/python
```

and use that one.

////

//// tab | Windows

```plaintext
C:\Users\user\code\awesome-project\.venv\Scripts;C:\Windows\System32
```

That means that the system will now start looking first for programs in:
