自动卸载打包安装的脚步

#!/bin/bash
###############################################################################

#功能：首先判断PTI是否运行，运行则停止。停止后卸载安装包(HUAbraspti)，接着删          #
#除安装目录并将以前打包生成的文件也进行删除。接着进行打包，首先执行pkgmk命令。          #
#执行过之后再执行pkgtrans命令，生成安装包文件(HUAbraspti.pkg)。执行安装包文件,       #
#进行安装该安装包。安装成功之后，紧接着更新安装目录下的conf目录中的配置文件。           #
#                                                                             #

#     Author  ChengYu                                                         #

#运行须知：如果在/opt/auto/ 目录下有conf目录则在安装完成之后将会覆盖安装路径下         #
#的conf目录，如果不存在则直接完成安装，在执行启动程序，需要手工修改配置文件。           #
