Git is a distributed version control system. Git is free software distributed under the GPL. Git has a mutable index called stage. A B note: 1、git diff 比较本地与stage区;git diff --cached 比较stage与版本库中 2、git rm并git commit了的东西,为何在git reflog中无法查看 3、git log是啥 4、如果以mxw登陆记录修改? 5、只要把每台电脑的Key都添加到GitHub,就可以在每台电脑上往GitHub推送(所以一个SSH密钥对应一台电脑?) ggg ggg_fixbug1
