## Variable de Entorno `PATH`

Hay una variable de entorno **especial** llamada **`PATH`** que es utilizada por los sistemas operativos (Linux, macOS, Windows) para encontrar programas a ejecutar.

El valor de la variable `PATH` es un string largo que consiste en directorios separados por dos puntos `:` en Linux y macOS, y por punto y coma `;` en Windows.

### Step 3: create a *path operation* { #step-3-create-a-path-operation }

#### Path { #path }

"Path" here refers to the last part of the URL starting from the first `/`.

So, in a URL like:

```
https://example.com/items/foo
```

...the path would be:

```
/items/foo
```

/// info

A "path" is also commonly called an "endpoint" or a "route".

## `PATH` 환경 변수

**`PATH`**라고 불리는, **특별한** 환경변수가 있습니다. 운영체제(Linux, Windows, macOS 등)에서 실행할 프로그램을 찾기위해 사용됩니다.

변수 `PATH`의 값은 Linux와 macOS에서는 콜론 `:`, Windows에서는 세미콜론 `;`으로 구분된 디렉토리로 구성된 긴 문자열입니다.

예를 들어, `PATH` 환경 변수는 다음과 같습니다:

//// tab | Linux, macOS

* Toma cada **request** que llega a tu aplicación.
* Puede entonces hacer algo a esa **request** o ejecutar cualquier código necesario.
* Luego pasa la **request** para que sea procesada por el resto de la aplicación (por alguna *path operation*).

     * @param path The path to match.
     * @return The matching FtpAuthentication object, or null if no match is found.
     */
    public FtpAuthentication get(final String path) {
        if (path == null) {
            return null;
        }

        for (final FtpAuthentication auth : authenticationList) {
            if (auth.matches(path)) {
                return auth;

tls              (on|off)    set to 'on' to enable TLS
tls_skip_verify  (on|off)    trust server TLS without verification, defaults to "on" (verify)
client_tls_cert  (path)      path to client certificate for mTLS auth
client_tls_key   (path)      path to client key for mTLS auth
queue_dir        (path)      staging dir for undelivered messages e.g. '/home/events'
queue_limit      (number)    maximum limit for undelivered messages, defaults to '100000'

    have prod supersource, even if they have none. GWT is happy to ignore us
    when we specify a nonexistent path.

    (I hope that this workaround does not cause its own problems in the future.)

"Mounting" means adding a completely "independent" application in a specific path, that then takes care of handling everything under that path, with the _path operations_ declared in that sub-application.

### Top-level application { #top-level-application }

First, create the main, top-level, **FastAPI** application, and its *path operations*:

{* ../../docs_src/sub_applications/tutorial001.py hl[3, 6:8] *}
