交互式自动化脚本模板

作为一个运维人员，免不了会做很多自动化的脚本，服务器安装的自动化，服务环境搭建自动化，服务启动关闭自动化，数据备份恢复自动化等等。

有部分是直接放置在crontab里面按照时间来定运行周期的，还有一部分是手动操作的，对于手动操作这部分，自认最好是交互式的，根据初期定义的功能类型，根据选择的需求完成自动化的部署和实现。

下面就是工作中用的两种比较普遍的交互式自动化脚本的大致框架。

第一种：case函数是实现的交互式

#!/usr/bin/env bash #===============================================================================#          FILE: deploy.sh#         USAGE: ./deploy.sh #   DESCRIPTION: Interactive automated deployment script#       OPTIONS: ---#  REQUIREMENTS: ---#         NOTES: ---#        AUTHOR: Eric Wu, mesopodamia@gmail.com#       CREATED: 01/25/2014 11:44#      REVISION:  ---#===============================================================================function example001() {echo "example001"}function example002() {echo "example002"}function example003() {echo "example003"}echo " ----------------------------------------"echo " "echo "Please insert function Number:"echo " "echo "  [1] function001 "echo "  [2] function002 "echo "  [3] function003 "echo " "echo " ----------------------------------------"read Number;case "$Number" in    1)        example001 && exit 0;;;2)        example002 && exit 0;;;3)        example003 && exit 0;;;    *)        echo $"Usage: $0 {function001|function002|function003}"        exit 2esac

第二种：dialog函数是实现的交互式

#!/usr/bin/env bash #===============================================================================#                 FILE: deploy.sh#                USAGE: ./deploy.sh #   DESCRIPTION: Interactive automated deployment script#          OPTIONS: ---#  REQUIREMENTS: ---#                NOTES: ---#               AUTHOR: Eric Wu, mesopodamia@gmail.com#          CREATED: 01/25/2014 11:44#         REVISION:  ---#===============================================================================command -v dialogif [[ $? != 0 ]]; then yum install -y dialogfi function example001() {        echo "example001"}function example002() {        echo "example002"}function example003() {        echo "example003"}if dialog --title "Auto Deploy System" --radiolist "Choose one function" 20 60 14 1 "function001" on 2 "function002" off 3 "function003" off 2>output; then        select=`cat output`        if [ $select -eq 1 ]; then                example001        elif [ $select -eq 2 ]; then                example002        elif [ $select -eq 3 ]; then                example003        else                echo "Your select is wrong!!! please try again!"   fifi
