- What is Linux Oops? Parse error message
- What is LinuxOops? To parse the error message, specific code examples are required. Introduction Linux Oops refers to an error message output by the Linux kernel when a serious error occurs, similar to the blue screen error of Windows systems. When the Linux kernel encounters a serious error that cannot be handled, it will stop running and output an error log called Oops information. By analyzing this information, the problem can be located and debugged. Oops information example The following is a simple Linux Oops information display
