一、GIT发展史

同生活中的许多伟大事件一样，Git 诞生于一个极富纷争大举创新的年代。Linux 内核开源项目有着为数众广的参与者。绝大多数的 Linux 内核维护工作都花在了提交补丁和保存归档的繁琐事务上（1991－2002年间）。到 2002 年，整个项目组开始启用分布式版本控制系统 BitKeeper 来管理和维护代码。

到 2005 年的时候，开发 BitKeeper 的商业公司同 Linux 内核开源社区的合作关系结束，他们收回了免费使用 BitKeeper 的权力。这就迫使 Linux 开源社区（特别是 Linux 的缔造者 Linus Torvalds ）不得不吸取教训，只有开发一套属于自己的版本控制系统才不至于重蹈覆辙。他们对新的系统订了若干目标：
