This guide introduces four essential Linux commands—lsmod, lsof, lspci, and lsscsi—detailing their purpose, syntax, useful options, and practical output examples, helping system administrators quickly diagnose kernel modules, open files, PCI devices, and SCSI devices.
This guide introduces four essential Linux commands—lsmod, lsof, lspci, and lsscsi—detailing their purpose, syntax, key options, example outputs, and how to interpret each column for effective system monitoring and troubleshooting.
Learn how to use essential Linux commands—lsmod, lsof, lspci, and lsscsi—to inspect kernel modules, open files, PCI devices, and SCSI devices, including syntax, useful options, and practical examples that illustrate interpreting their output for effective system administration.
This article explains how PCIe width, speed, Max Payload Size, and Max Read Request affect network adapter performance, shows how to query and adjust these attributes with lspci and setpci, and provides formulas and examples for calculating the resulting PCIe bandwidth limits.
This article explains how PCIe width, speed, Max Payload Size, and Max Read Request affect network adapter performance, shows how to verify and adjust these settings with lspci and setpci commands, and provides formulas for calculating the resulting PCIe bandwidth limits.
This guide explains how to use the lspci command to display all PCI bus information, interpret its common options, and provides practical examples for listing devices, showing detailed info, and filtering by vendor, class, or connection type.
