The dmesg command can also be used to print and control the kernel ring buffer.
dmesg 命令也可用于打印和控制内核环缓冲区。
Note that kernel output goes to the kernel ring buffer and not to stdout, because stdout is process specific.
注意,内核的输出进到了内核回环缓冲区中,而不是打印到stdout上,这是因为stdout是进程特有的环境。
You may display the kernel ring buffer using the dmesg command, which displays these messages on standard output.
