dmesg -T

直接用dmesg显示系统信息，很难看

显示的时间没有办法看。

使用dmesg —help看到，如下：

Usage:
dmesg [options]

Display or control the kernel ring buffer.

Options:
-C, —clear clear the kernel ring buffer
-c, —read-clear read and clear all messages
-D, —console-off disable printing messages to console
-E, —console-on enable printing messages to console
-F, —file use the file instead of the kernel log buffer
-f, —facility restrict output to defined facilities
-H, —human human readable output
-k, —kernel display kernel messages
-L, —color[=] colorize messages (auto, always or never)
colors are enabled by default
-l, —level restrict output to defined levels
-n, —console-level set level of messages printed to console
-P, —nopager do not pipe output into a pager
-r, —raw print the raw message buffer
-S, —syslog force to use syslog(2) rather than /dev/kmsg
-s, —buffer-size buffer size to query the kernel ring buffer

Suspending/resume will make ctime and iso timestamps inaccurate.
