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

UNAME="uname -a"

printf "Gathering system information with the $UNAME command:\n\n"

$UNAME

#Command

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
