Print out kernel message or control ring buffer

Print out kernel message or control ring buffer

dmesg [ -c ] [ -n level ] [ -s bufsize ]

Options

-c
Clear the ring buffer contents after printing.
-sbufsize
Use a buffer of size bufsize to query the kernel ring buffer. This is 16392 by default. (The default kernel syslog buffer size was 4096 at first, 8192 since 1.3.54, 16384 since 2.1.113.) If you have set the kernel buffer to be larger than the default then this option can be used to view the entire buffer.
-nlevel
Set the level at which logging of messages is done to the console. For example, -n 1 prevents all messages, expect panic messages, from appearing on the console. All levels of messages are still written to /proc/kmsg, so syslogd(8) can still be used to control exactly where kernel messages appear. When the -n option is used, dmesg will not print or clear the kernel ring buffer.

When both options are used, only the last option on the command line will have an effect.
