学习shell做的第一个脚本,感谢云知梦李强强老师的shell编程教程
创建shell脚本文件:
touch menu.sh
touch index.sh
touch welcome.sh
赋予脚本文件可执行权限:
chmod a+x menu.sh index.sh welcome.sh
menu.sh
#!/bin/bash #menu.sh function menu(){ title="My Home" name="Randy" time=`date +%Y-%m-%d` cat << qaz ####################################################################### ## ***`echo -e "\e[32m $title \e[0m"`*** ## ####################################################################### ## 1)Add a user ## ## 2)View all users ## ## 3)Set passwd for user ## ## 4)Delete a user ## ## 5)Print disk space ## ## 6)Print mem space ## ## 7)Retrun menu ## ## 8)Logout ## ## 9)Quit ## ####################################################################### ## Name:$name Date:$time ## ####################################################################### qaz }
4.index.sh
#!/bin/bash #index.sh function index() { clear . menu.sh menu while true do read -p "Please input a option:" option case $option in 1) read -p "Please input username:" name useradd $name &>/dev/null if [ $? -eq 0 ];then echo "user ${name} is created successfully!!!" else echo "user ${name} is created failly!!!" fi ;; 2) str=`cat /etc/passwd | awk -F: ‘{print $1}‘` echo -e "\e[32m$str\e[0m" ;; 3) read -p "input the username:" name read -p "set password for the user:" pass echo $pass | passwd --stdin $name &>/dev/null if [ $? -eq 0 ];then str="${name}‘s password is set successfully" echo -e "\033[30;47$str\033[0m" else str="${name}‘s password is set failly!!!" echo -e "\033[31;47m$str\033[0m" fi ;; 4) read -p "delete the user:" name userdel -r $name &>/dev/null if [ $? -eq 0 ];then str="user ${name} is delete successfully!!!" echo -e "\033[30;47m$str\033[0m" else str="user ${name} is delete failly!!!" echo -e "\033[31;47m$str\033[0m" fi ;; 5) str=`df -Th` echo -e "\033[30;47m$str\033[0m" ;; 6) str=`free -m` echo -e "\033[30;47m$str\033[0m" ;; 7) clear menu ;; 8) echo -e "\e[31mLogout ...\e[0m" sleep 1 break ;; 9) echo -e "\e[31mQuit successfully!!!\e[0m" exit ;; *) str="Input error please re-enter" echo -e "\033[30;47m$str\033[0m" ;; esac done }
5.welcome.sh
#!/bin/bash #welcome clear echo -e "\e[31mWelcome\e[0m" while true do read -p ‘Please enter user name (Quit please input "q") :‘ name if [ $name = "q" ] then break else read -p ‘Please enter user password:‘ password if [ $name = ‘admin‘ ] && [ $password = ‘admin‘ ] then str="Login successfully,Please Wait ......" echo -e "\e[31m$str\e[0m" sleep 2 . index.sh index else str="Login failly" echo -e "\e[31m$str\e[0m" fi fi done
