# 教程：查看有关任务和使用 AWS CLI 执行任务的信息
<a name="mw-cli-tutorial-task-info"></a>

本教程演示了如何使用 AWS Command Line Interface (AWS CLI) 查看有关您已完成的维护时段任务的详细信息。

如果您直接从 [教程：使用 AWS CLI 创建和配置维护时段](maintenance-windows-cli-tutorials-create.md) 继续，请确保您已为维护时段留出足够时间至少运行一次，以查看其执行结果。

在按照本教程中的步骤操作时，请将以斜体*红色*文本显示的值替换为您自己的选项和 ID。例如，请将维护时段 ID *mw-0c50858d01EXAMPLE* 和实例 ID *i-02573cafcfEXAMPLE* 替换为您创建的资源的 ID。

**要查看有关任务和使用 AWS CLI 执行任务的信息**

1. 运行以下命令，查看特定维护时段的任务执行列表。

------
#### [ Linux & macOS ]

   ```
   aws ssm describe-maintenance-window-executions \
       --window-id "mw-0c50858d01EXAMPLE"
   ```

------
#### [ Windows ]

   ```
   aws ssm describe-maintenance-window-executions ^
       --window-id "mw-0c50858d01EXAMPLE"
   ```

------

   系统返回类似于以下内容的信息。

   ```
