Hunter的大杂烩 技术学习笔记

最近尝试用jenkins在定时构建环节统计开发人员的代码变更情况，统计方法参考http://qa.blog.163.com/blog/static/19014700220142131203191/。结果实际运行时遇到一个奇怪的问题，在命令行中明明运行很好的git shortlog命令，放到jenkins里面运行，总是无输出，在度娘上搜了一个下午，一开始以为是环境变量问题（参考https://blog.csdn.net/zzusimon/article/details/57080337），加上”#!/bin/bash -ilex”后，仍然不行，最后还是bing搜索给力，在stackoverflow上找到解决方案（https://stackoverflow.com/questions/43041659/git-shortlog-does-not-show-output-in-jenkins-shell），最后成型的脚本如下，供参考（btw:博客黏贴代码时缩进没了，请自行处理吧~~）：
