晋太元中,武陵人捕鱼为业。缘溪行,忘路之远近。忽逢桃花林,夹岸数百步,中无杂树,芳草鲜美,落英缤纷。渔人甚异之,复前行,欲穷其林。 林尽水源,便得一山,山有小口,仿佛若有光。便舍船,从口入。初极狭,才通人。复行数十步,豁然开朗。土地平旷,屋舍俨然,有良田、美池、桑竹之属。阡陌交通,鸡犬相闻。其中往来种作,男女衣着,悉如外人。黄发垂髫,并怡然自乐。 见渔人,乃大惊,问所从来。具答之。便要还家,设酒杀鸡作食。村中闻有此人,咸来问讯。自云先世避秦时乱,率妻子邑人来此绝境,不复出焉,遂与外人间隔。问今是何世,乃不知有汉,无论魏晋。此人一一为具言所闻,皆叹惋。余人各复延至其家,皆出酒食。停数日,辞去。此中人语云:“不足为外人道也。”(间隔 一作:隔绝) 既出,得其船,便扶向路,处处志之。及郡下,诣太守,说如此。太守即遣人随其往,寻向所志,遂迷,不复得路。 南阳刘子骥,高尚士也,闻之,欣然规往。未果,寻病终。后遂无问津者。

lshw: HardWare LiSter for Linux
===============================
lshw is a small tool to provide detailed information on the hardware configuration of the machine. It can report exact memory configuration, firmware version, mainboard configuration, CPU version and speed, cache configuration, bus speed, etc. on DMI-capable x86 or EFI (IA-64) systems and on some ARM and PowerPC machines (PowerMac G4 is known to work).
Information can be output in plain text, XML or HTML.
It currently supports DMI (x86 and EFI only), OpenFirmware device tree
(PowerPC only), PCI/AGP, ISA PnP (x86), CPUID (x86), IDE/ATA/ATAPI, PCMCIA
(only tested on x86), USB and SCSI.
Installation
------------
1. Requirements
- Linux 2.4.x, 2.6.x, 3.x or 4.x (2.2.x might work, though)
- a PA-RISC-, Alpha-, IA-64- (Itanium-), PowerPC-, ARM- or x86- based machine
- cmake, GNU make or Ninja
- an ANSI (or close enough to ANSI compliance) C++ compiler (tested with g++ 2.95.4 and 3.x)
- for the (optional) GTK+ graphical user interface, you will need a
complete GTK+ development environment (gtk3-devel on RedHat/Fedora derivatives)
- for optional SQLite feature install SQLite
- for optional zlib feature install zlib and gzip
2. Use cmake options to decide feature set:
- -DGUI=OFF - disable graphical user interface version og lshw
- -DZLIB=ON - enable reading of gzipped datafiles
- -DSQLITE=ON - enable SQLite support
- -DPOLICYKIT=ON - enable PolicyKit integration
- -DNOLOGO=ON - don't install logos with copyright
3. Do configuration and build by
$ mkdir build && cd build
$ cmake .. -GNinja <options>
$ ninja-build
4. If you want to install the result, do:
$ ninja-build install
Getting help
------------
1. the lshw home page is http://lshw.ezix.org/
2. bug reports and feature requests: http://ezix.org/project/newticket?component=lshw
Please make sure you include enough information in your bug report: XML output from lshw is preferred over text or HTML, indicate the affected version of lshw, your platform (i386, x86-64, PA-RISC, PowerPC, etc.) and your distribution.
NOTE TO DISTRIBUTIONS
---------------------
By default, lshw includes its own lists of PCI IDs, USB IDs, etc. but will also look for this information in
/usr/share/lshw/,
/usr/local/share/,
/usr/share/,
/etc/,
/usr/share/hwdata/,
/usr/share/misc/
If compiled with zlib support, lshw will look for `file`.gz first, then for `file`.
Statically-linked and/or compressed binaries can be built by using
$ mkdir build && cd build
$ cmake .. -DSTATIC=ON
$ ninja
or
$ mkdir build && cd build
$ cmake .. -GNinja
$ ninja compressed
Building compressed binaries requires `upx` (cf. https://upx.github.io/).
Release management and data files maintenance
---------------------------------------------
Create release tarball,
1. Edit CMakeLists.txt to set version
2. Run
$ mkdir build && cd build
$ cmake .. -DMAKE_RELEASE=ON
$ make release
Update hwdata files:
$ make refresh_hwdata
