Which command would provide a summarized report on detected hardware errors at the kernel level in Red Hat systems?

The command that provides a summarized report on detected hardware errors at the kernel level in Red Hat systems is related to the Automatic Bug Reporting Tool (ABRT). This tool helps to handle and report system crashes, including those due to hardware failures. When a crash occurs and is detected by the kernel, ABRT collects relevant information and can summarize the errors, which is essential for troubleshooting and addressing hardware issues.

This makes ABRT particularly useful in environments where system reliability and performance need to be closely monitored, as it aids in identifying underlying hardware problems that may not be immediately apparent.

The other commands listed serve different purposes and do not provide summaries of hardware errors. For instance, 'lsblk' is used for listing block devices, 'lpq' relates to printing jobs in a printer queue, and 'lpr' is a command for submitting print jobs. These commands do not interact with kernel error reporting or provide diagnostics related to hardware failures.
