Few days back one of my friend came up to me and asked if I can tell him a command to view details of hardware on his Linux machine. Given my knowledge all I could recall was, using /proc/cpuinfo to get information about CPU, using /proc/meminfo to get information about Memory and using commands like lspci and lsusb to get information about PCI and USB devices. However yesterday just out of curiosity I looked up at my system and found a command lshw. This command helps in generating entire system report and provides good enough details about various components of the system. It was even able to find out vendor id for my optical drive ! One thing which I couldn't decipher though was the fact that the command always complained about running under root credentials. Why would such a command have to be executed under root credentials ?
