dmesg: Show kernel error messages.
$ dmesg --level err
try on your machine
The command "dmesg --level err" is used to display kernel error messages from the last boot in a Linux system.
Here is a breakdown of each component:
- "dmesg" is a command-line utility in Linux used to display the kernel ring buffer, which contains important messages from the kernel.
- "--level err" is an option that filters the output of dmesg to only show error-level messages. In this case, it only displays kernel error messages.
By running this command, you can get a list of error messages that occurred during the last boot, which can be helpful for troubleshooting and diagnosing issues in the system.
