## Crear y Usar Variables de Entorno { #create-and-use-env-vars }

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

called "MLCI" that makes testing more convenient: it can execute any full CI job
against a pending change. Search for "MLCI" internally to find it.

You may invoke a CI script of your choice by following these instructions:

```bash
cd tensorflow-git-dir

# Here is a single-line example of running a script on Linux to build the
# GPU version of TensorFlow for Python 3.12, using the public TF bazel cache and
# a local build cache:

#!/bin/bash

if [ -n "$TEST_DEBUG" ]; then
	set -x
fi

pkill minio
pkill kes
rm -rf /tmp/xl

go install -v github.com/minio/mc@master
cp -a $(go env GOPATH)/bin/mc ./mc

if [ ! -f ./kes ]; then
	wget --quiet -O kes https://github.com/minio/kes/releases/latest/download/kes-linux-amd64 &&
		chmod +x kes
fi

if ! openssl version &>/dev/null; then
	apt install openssl || sudo apt install opensssl
fi

## Umgebungsvariablen erstellen und verwenden { #create-and-use-env-vars }

Sie können Umgebungsvariablen in der **Shell (Terminal)** erstellen und verwenden, ohne Python zu benötigen:

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

<div class="termy">

```console
// Sie können eine Umgebungsvariable MY_NAME erstellen mit
$ export MY_NAME="Wade Wilson"

// Dann können Sie sie mit anderen Programmen verwenden, etwa
$ echo "Hello $MY_NAME"
