我正在尝试对以下文字进行排序：

Tue 2014 Nov 25 07:44:44 berlin VPN connection succeed
Tue 2014 Nov 25 08:01:12 paris VPN connection succeed
Tue 2014 Nov 25 08:44:45 berlin VPN connection succeed
Tue 2014 Nov 25 09:01:18 paris VPN connection succeed
Tue 2014 Nov 25 09:12:52 london VPN connection succeed
Tue 2014 Nov 25 09:44:45 berlin VPN connection succeed
Tue 2014 Nov 25 10:44:50 berlin VPN connection succeed
Tue 2014 Nov 25 10:57:34 dallas VPN connection succeed
Tue 2014 Nov 25 11:35:56 london VPN connection succeed
Tue 2014 Nov 25 11:47:05 amsterdam VPN connection succeed
Tue 2014 Nov 25 11:57:34 dallas VPN connection succeed
Tue 2014 Nov 25 12:47:06 amsterdam VPN connection succeed
Tue 2014 Nov 25 12:57:33 dallas VPN connection succeed
Tue 2014 Nov 25 13:47:06 amsterdam VPN connection succeed
Tue 2014 Nov 25 13:57:33 dallas VPN connection succeed
Tue 2014 Nov 25 14:47:07 amsterdam VPN connection succeed
Tue 2014 Nov 25 14:57:33 dallas VPN connection succeed
Tue 2014 Nov 25 09:14:07 london VPN connection disconnected
Tue 2014 Nov 25 09:35:05 paris VPN connection disconnected
Tue 2014 Nov 25 10:57:26 amsterdam VPN connection disconnected
Tue 2014 Nov 25 11:35:41 berlin VPN connection disconnected
Tue 2014 Nov 25 11:39:00 london VPN connection disconnected

我想按2个标准排序：
1.首先排序第6列（城市名称）
2.然后按时间排序（第5列）

该文本来自一个名为text.txt的文件，我使用cat命令。

我使用以下命令：

cat text.txt | sort -k6 -k5,1n

然而，它产生以下输出（它对城市名称进行排序，但不对时间字段进行排序）：

Tue 2014 Nov 25 10:57:26 amsterdam VPN connection disconnected
Tue 2014 Nov 25 11:47:05 amsterdam VPN connection succeed
Tue 2014 Nov 25 12:47:06 amsterdam VPN connection succeed
Tue 2014 Nov 25 13:47:06 amsterdam VPN connection succeed
Tue 2014 Nov 25 14:47:07 amsterdam VPN connection succeed
Tue 2014 Nov 25 11:35:41 berlin VPN connection disconnected
Tue 2014 Nov 25 07:44:44 berlin VPN connection succeed
Tue 2014 Nov 25 08:44:45 berlin VPN connection succeed
Tue 2014 Nov 25 09:44:45 berlin VPN connection succeed
Tue 2014 Nov 25 10:44:50 berlin VPN connection succeed
Tue 2014 Nov 25 10:57:34 dallas VPN connection succeed
Tue 2014 Nov 25 11:57:34 dallas VPN connection succeed
Tue 2014 Nov 25 12:57:33 dallas VPN connection succeed
Tue 2014 Nov 25 13:57:33 dallas VPN connection succeed
Tue 2014 Nov 25 14:57:33 dallas VPN connection succeed
Tue 2014 Nov 25 09:14:07 london VPN connection disconnected
Tue 2014 Nov 25 11:39:00 london VPN connection disconnected
Tue 2014 Nov 25 09:12:52 london VPN connection succeed
Tue 2014 Nov 25 11:35:56 london VPN connection succeed
Tue 2014 Nov 25 09:35:05 paris VPN connection disconnected
Tue 2014 Nov 25 08:01:12 paris VPN connection succeed
Tue 2014 Nov 25 09:01:18 paris VPN connection succeed

如何解决此问题，以便我可以对1.城市名称进行排序，然后在时间字段上进行排序？

有人可以帮我这个吗？

您可以简化sort。这个有效：

sort -k6,6 file
Tue 2014 Nov 25 10:57:26 amsterdam VPN connection disconnected

这是有效的，因为您的时间戳使用HH:MM:SS格式。

答案 1 :(得分：1)

如果您执行sort -k 6，则会对字段6，然后是7,8,9等进行排序。从手册中：

  

KEYDEF是F [.C] [OPTS] [，F [.C] [OPTS]]的开始和停止位置，   其中F是字段编号，C是字段中的字符位置;   两者都是原点1，停止位置默认为该行   端

如果您只想对字段6进行排序，请将其明确设置为开始和停止字段：

sort -k 6,6

如果要对6进行排序，然后对5进行排序，请执行以下操作：

sort -k 6,6 -k 5,5
