[root@localhost ~]# ls
anaconda-ks.cfg studypy
[root@localhost ~]# cd studypy/
[root@localhost studypy]# ls
README.md
6.創建新文件push到github中
[root@localhost studypy]# touch test.md
[root@localhost studypy]# ls
README.md test.md
[root@localhost studypy]# git add test.md
[root@localhost studypy]# git commit -m "add test.md"
