如何从 Openstack nova 列表中仅获取 ID 名称和网络字段
How to get only ID Name and Networks fields from Openstack nova list
我的 nova 列表输出为：
# nova list
+--------------------------------------+---------------+--------+------------+-------------+-----------------------------------------------------------------------------------------+
| ID | Name | Status | Task State | Power State | Networks |
+--------------------------------------+---------------+--------+------------+-------------+-----------------------------------------------------------------------------------------+

+--------------------------------------+---------------+--------+------------+-------------+-----------------------------------------------------------------------------------------+
我只想提取 ID 名称网络。
# nova list | sed 's/ //g'| cut -d'|' -f 2,3,7
+--------------------------------------+---------------+--------+------------+-------------+-----------------------------------------------------------------------------------------+
ID|Name|Networks

问题：
我的 table 格式乱七八糟 up.how 只得到如下所示的 ID 名称和网络字段。

最简单的方法是使用 --fields，如：
$ nova list --fields name,networks
+--------------------------------------+--------------------------------------------+--------------------------------------------------------------+

+--------------------------------------+--------------------------------------------+--------------------------------------------------------------+
如果您更喜欢使用较新的客户端 openstack 客户端，选项为：
openstack server list -c Name -c Networks -f html
-f 允许您选择输出格式 csv、html、json、table、value、yaml。
