嵌入式Linux体系上提取有用的体系信息

下面的脚本可以一次性获取嵌入式Linux系统上有用的系统信息，包括网络信息，存储信息，环境信息等等。 它一同支撑周期性工作，可以用于系统监测，比如检查内存泄露等。 注：由于我用的busybox中的top不支撑-n 选项，因此使用了后台工作，一定时辰后再杀死top进程的办法。 top 指令如果支撑-n 选项就非常简略了。 使用办法： $ sysinfo.sh -h usage: sysinfo.sh http://www.aaafaipiao.com/linked/20130315.do  [options]     show system information.     Without option, it will show all information. options:     -c  : show how many times.     -d: show disk information.     -e: show environment.     -g: show general information.     -i : show information every  seconds.     -m: show memory information.     -n: show network information.     -p: show process information.     -r: show release information.     -h: show help #!/bin/sh
