Puedes **crear** y usar variables de entorno en la **shell (terminal)**, sin necesidad de Python:

//// tab | Linux, macOS, Windows Bash

<div class="termy">

```console
// Podrías crear una env var MY_NAME con
$ export MY_NAME="Wade Wilson"

// Luego podrías usarla con otros programas, como
$ echo "Hello $MY_NAME"

Hello Wade Wilson
```

</div>

////

//// tab | Windows PowerShell

<div class="termy">

### 3. Setup MinIO with etcd

MinIO server expects environment variable for etcd as `MINIO_ETCD_ENDPOINTS`, this environment variable takes many comma separated entries.

```
export MINIO_ETCD_ENDPOINTS=http://localhost:2379
minio server /data
```
