基本断网，设计conky
生活 conky linux 桌面 美化
他丫的广电Cable猫上网又必须用Win-only客户端了，多次交涉无果，准备换电信联通的。
不开客户端只能随机地上一小部分网站，可喜的是包括google、is-programmer。开着网页代理能维持基本上网需要。
周末了无聊，就设计conky。连不上网缺乏素材啊缺乏素材~~~，所以也没设计啥高端功能：
下面是conkyrc，严重依赖我的硬件：

我的系统上有两个hwmon（监控硬件状态）设备，开机时内核分配的编号不确定，所以无法用conky的hwmon解决。就写了个脚本，在运行conky前先调用这个脚本，选择适当hwmon链接到一个固定目录：
#!/bin/sh
mkdir -p /tmp/.conky
rm -rf /tmp/.conky/hwmon
if [ -e "/sys/class/hwmon/hwmon0/name" ]; then
ln -s "/sys/class/hwmon/hwmon0" /tmp/.conky/hwmon
else
ln -s "/sys/class/hwmon/hwmon1" /tmp/.conky/hwmon
fi
工具getnum是用来从文本文件中读取数字的，用法是：getnum 文件 A B，最后输出的结果是文件中读取的浮点数字N/B，保留A位输出。
在网上看到的例子是用cat和echo解决的，但我怕效率低，就自己写了个：
#include <stdio.h>
#include <stdlib.h>
int main (int argc, char *argv[])
{
freopen(argv[1], "r", stdin);
if (argc != 4)
exit(1);
float num;
scanf("%f", &num);
num /= atoi(argv[3]);
char fm[8];
snprintf(fm, 8, "%%.%sf", argv[2]);
printf(fm, num);
return 0;
}
