每天写点shell脚本 （持续更新）

1、显示系统信息脚本

#!/bin/bash
#A system information gathering script
#Command 1
UNAME="uname -a"
printf "Gathering system information with the $UNAME command:\n\n"
$UNAME

#Command 2
DISKSPACE="df -h"
printf "Gathering diskspace information with the $DISKSPACE command: \n\n"
$DISKSPACE
~           

 以上实例运行结果：

$ sh test4.sh
