grep 是一个强大的文本搜索工具,用于搜索包含指定模式的行。 -e 选项后面跟的是要搜索的模式,可以指定多个模式,用 | 分隔。在这个例子中,要搜索的模式是 'kill'、'oom' 和 'out of memory'。 过滤模式: 'kill|oom|out of memory':这个模式表示搜索包含 'kill'、'oom' 或 'out of memory' 的行。这...

dmesg命令: 友好的显示log时间信息: dmesg -T 清空dmesg: dmesg -c 查看OOM: dmesg -T | grep ‘Out of memory’
5. 搜索包含特定字符串的被检测到的硬件(dmesg -T打印时间) 由于‘dmesg’命令的输出实在太长了,在其中搜索某个特定的字符串是非常困难的。因此,有必要过滤出一些包含‘usb’ ‘dma’ ‘tty’ ‘memory’等字符串的日志行。grep 命令 的‘-i’选项表示忽略大小写。 [root@localhost ~]# dmesg...
dmesg -T | grep -i oom 1、如果发现自己的java进程悄无声息的消失了,几乎没有留下任何线索,那么dmesg一发,很有可能有你想要的。 1 2 3 4 5 6 7 8 9 10 11 [root@host-172-21-210-40 ~]# dmesg -T |grep score [Thu Oct 29 08:09:25 2020] Out of memory: Kill process 13062 (tidb-...
