Using The Console Interactively

The console of devices running Linux can sometimes be flooded with system and kernel logs, making it difficult to use interactively.

If you’re using the console interactively, you may want to run dmesg -n 1 to prevent all messages, except emergency (panic) messages. Run dmesg -n 4 to restore the default behavior, and run dmesg -n 7 to log all messages to the console.
