## Tạo và Sử dụng các Biến Môi Trường

Bạn có thể **tạo** và sử dụng các biến môi trường trong **shell (terminal)**, mà không cần sử dụng Python:

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

<div class="termy">

```console
// Bạn có thể tạo một biến môi trường MY_NAME với
$ export MY_NAME="Wade Wilson"

// Sau đó bạn có thể sử dụng nó với các chương trình khác, như
$ echo "Hello $MY_NAME"

            //
            // So that is why we cancel only in the case of CAS success.
            taskFuture.cancel(false);
          }
        };
    // Adding the listener to both futures guarantees that newFuture will always be set. Adding to
    // taskFuture guarantees completion if the callable is invoked, and adding to outputFuture
    // propagates cancellation if the callable has not yet been invoked.

        TestScriptEngine engine1 = new TestScriptEngine("engine1");
        TestScriptEngine engine2 = new TestScriptEngine("engine2");

        engine1.register();
        engine2.register();

        // Verify both engines are registered
        ScriptEngine retrieved1 = scriptEngineFactory.getScriptEngine("engine1");
        ScriptEngine retrieved2 = scriptEngineFactory.getScriptEngine("engine2");

        assertNotNull(retrieved1);

        FessJsonResourceProvider provider1 = new FessJsonResourceProvider();
        FessJsonResourceProvider provider2 = new FessJsonResourceProvider();

        assertNotSame(provider1, provider2);

        // Both instances should have the same behavior
        assertEquals(provider1.isNullsSuppressed(), provider2.isNullsSuppressed());
        assertEquals(provider1.isPrettyPrintSuppressed(), provider2.isPrettyPrintSuppressed());
