【Shell剧本练习】得出的结论是当前用户

推断是否当前用户root。假设是暗示root用户，假设而不是提示对于普通用户

#!/bin/bash

#title: testus.sh

#author: orangleliu

#date: 2014-08-09

#desc: get current user, if it is root user, tell us it is super user or tell us is a common user

#================

#Function CheckUser

#================

CheckUser()

{

	check_user=`whoami`

	if [ "$check_user" == "root" ]

	then

		echo "You are $check_user user"

		echo "You are a super amdin"

	else

		echo "You are $check_user user"

		echo "You are a common user"

	fi

}

#================

#Function Main

#================

Main()

{

	CheckUser

}

Main

运行结果

[orangle@localhost shell]$ bash testus.sh
You are orangle user
You are a common user
[orangle@localhost shell]$ su - root
Password:
[root@localhost ~]# bash /home/orangle/shell/testus.sh
You are root user
You are a super amdin

一方面之前没有系统的写过shell脚本。一方面是通过小案例来学习和总结shell。

而不是通过各种语法的学习然后再去写脚本。
