如何解析和替换awk中的GPU日志？

Question

我有grep输出：

Nov 07 16:03:23 SA1789 miner[1397]: GPU4 not responding                   
Nov 07 16:03:23 SA1789 miner[1397]: Thread(s) not responding. Restarting.
Nov 07 16:02:25 SA0888 miner[1505]: GPU12 not responding                            
Nov 07 16:02:25 SA0888 miner[1505]: Thread(s) not responding. Restarting.           
Nov 07 16:04:17 SA0888 miner[1505]: GPU12 not responding                       
Nov 07 16:04:17 SA0888 miner[1505]: Thread(s) not responding. Restarting.

想要得到这个：

Nov 07 16:03:23 ==> GPU4
Nov 07 16:02:25 ==> GPU12
Nov 07 16:04:17 ==> GPU12

awk '/GPU/{s=index($7,":"); $7=substr($7,s+1,length($7)-s-1); print $1" "$2" "$3" => "$7}'

很抱歉，我只是菜鸟，只需要专家的快速解决方案即可。

简单的awk表达式：

$ awk '/GPU/{ print $1, $2, $3, "==>", $6 }' file
Nov 07 16:03:23 ==> GPU4
Nov 07 16:02:25 ==> GPU12
Nov 07 16:04:17 ==> GPU12
