hwconfig命令详解

最近经常要测试新硬件，了解硬件的具体型号和参数就非常重要，过去经常透过lspci, dmidecode, dmesg, ethtool, lshal, megacli等命令和各种/proc信息来了解，需要对这些工具很熟悉, 貌似比较不方便和准确。

今天看到某同学用的hwconfig感觉信息很专业，推荐给大家。这里可以下载, 感谢微博@frostwatcher同学.

hwconfig透过收集上面提到的各种信息, 然后根据wiki或者厂家公布的设备识别码, 进一步加工,给用户一个直观的信息.

不废话,效果如下：

$ uname -r

2.6.18-164.el5

$ hwconfig  -h

usage:  hwconfig [-dhnv] [-t timeout] [-r file] [-x file] [-o file]

        -d  show debugging information

        -h  show usage

        -n  don't break output lines

        -o  write output to file (- for stdout)

        -r  write raw source to file (- for stdout)

        -t  abort after timeout seconds

        -v  show version

        -x  write xml to file (- for stdout)

##简约模式

$ sudo hwconfig   

hwconfig: warning: could not run megarc; please yinst megarc

##这个是非常详细的模式, 了解到各个设备的细节.

$ sudo hwconfig -x cfg.xml

$ less cfg.xml

</system>

看着信息还是很专业的，结果微博上有同学反映是个脚本，我看了下原来hwconfig真的是个脚本：

#!/usr/bin/perl -w

# $Id$

$ENV{PATH} = "/etc/bin:/sbin:/usr/sbin:/bin:/usr/bin:/usr/local/bin:/usr/local/sbin:/home/opt:/opt/MegaRAID/MegaCli:/usr/StorMan";

use strict 'vars';

use Getopt::Std;

use POSIX;

...

$ cat `which hwconfig `|wc -l    

9101

挺佩服这帮人的，脚本也能有这样的耐心，写这么长。

祝大家玩得开心！
