About to print KERNEL messages on terminal

Question

According to manual page it told that if priority of message's log level is higher than default set log level then it will be printed on terminal. But when I had used sentence like

printk(KERN_ALERT " MESSAGE ")

I am facing problem to print message on terminal. Because the default priority is set to 4 and KERN_ALERT has priority 1, which is higher.

So, how can I print message on terminal?

Answer 1

It should print messages to the console, not to the terminal. Sometimes the console and the terminal seems the same, but it is not. Edit /proc/sys/kernel/printk to set up the lowest priority to print in console
