使用lshw
# lshw --help
Hardware Lister (lshw) -
usage: lshw [-format] [-options ...]
lshw -version
-version print program version ()
format can be
-html output hardware tree as HTML
-xml output hardware tree as XML
-json output hardware tree as a JSON object
-short output hardware paths
-businfo output bus information
options can be
-class CLASS only show a certain class of hardware
-C CLASS same as '-class CLASS'
-c CLASS same as '-class CLASS'
-disable TEST disable a test (like pci, isapnp, cpuid, etc. )
-enable TEST enable a test (like pci, isapnp, cpuid, etc. )
-quiet don't display status
-sanitize sanitize output (remove sensitive information like serial numbers, etc.)
-numeric output numeric IDs (for PCI, USB, etc.)
-notime exclude volatile attributes (timestamps) from output
lshw > hardware.txt
会记录所有硬件的相关信息
但可以使用其他命令查看
例如内存相关可以使用lsmem和lshw中的显示内存部分是相同的
cpu可以使用lscpu查看
