有如下的日志/var/log/message.log,要求把最新时间的日志打印出来。
Time,Entity,Severity,Node,Desc 00:00:01 04/25/2016 ,Node,Info,0,IMG Control Link is Up 00:00:01 04/25/2016 ,Node,Info,0,HostAlarm(Software License Verified) 00:00:01 04/25/2016 ,Node,Info,0,HostAlarm(Software Versions Matched) 11:16:45 04/25/2016 ,Node,Info,0,IMG Control Link is Up 11:16:45 04/25/2016 ,Node,Info,0,HostAlarm(Software License Verified) 11:16:45 04/25/2016 ,Node,Info,0,HostAlarm(Software Versions Matched) 12:11:46 04/25/2016 ,Node,Info,0,IMG Control Link is Up 12:11:46 04/25/2016 ,Node,Info,0,HostAlarm(Software License Verified) 12:11:46 04/25/2016 ,Node,Info,0,HostAlarm(Software Versions Matched)
比如,这里最新时间的日志应该是:
12:11:46 04/25/2016 ,Node,Info,0,IMG Control Link is Up 12:11:46 04/25/2016 ,Node,Info,0,HostAlarm(Software License Verified) 12:11:46 04/25/2016 ,Node,Info,0,HostAlarm(Software Versions Matched)
将这一段打印出来,命令精简越好。
grep "`grep [^0-9] /var/log/message.log |cut -d , -f 1|uniq|tail -1`" /var/log/message.log grep "`grep [^0-9] /var/log/message.log |awk -F ‘,‘ ‘{print $1}‘|uniq |tail -1`" /var/log/message.log grep "`tail -1 /var/log/message.log |awk -F ‘,‘ ‘{print $1}‘`" /var/log/message.log
我感觉写的好臃肿,但是目前是实现了。在改进吧。
