9 Un­cover sys­tem in­for­ma­tion

Linux Format - - ESCAPE WINDOWS -

The Ter­mi­nal pro­vides a host of tools for di­vulging key info about your hard­ware. Start with the fol­low­ing com­mand for a ta­ble-like sum­mary of your hard­ware (list hard­ware): $ sudo lshw -short You can also out­put a full-blown de­tailed re­port for view­ing in your web browser: $ sudo lshw -html > sys­info.html Other re­lated tools in­clude lscpu (list pro­ces­sor in­for­ma­tion), ls­blk (list block stor­age), lspci (list in­ter­nal hard­ware) and lsusb (USB de­vices). They all work slightly dif­fer­ently – for ex­am­ple, sudo lspci -v pro­vides a handy sum­mary, while lsusb works best if you first identify the de­vice you wish to check out via sudo lsusb , then use the fol­low­ing com­mand based on its bus and de­vice num­ber: $ sudo lsusb -D /dev/bus/usb/00x/00y One fi­nal tool – dmide­code – can pro­vide use­ful in­for­ma­tion via the -t flag and key­words in­clud­ing bios, base­board (moth­er­board), pro­ces­sor, mem­ory and chas­sis – for ex­am­ple, sudo dmide­code -t mem­ory . Be warned, how­ever, as the DMI ta­bles it polls aren’t al­ways ac­cu­rate, so don’t be shocked if things don’t stack up.

Use lshw to cre­ate a HTML file sum­maris­ing your PC’s hard­ware.
