- 前面的數字是Git的commit id。
當前的最新版本是append GPL，想要回到add distribute版本，使用$ git reset --hard HEAD^命令，其中HEAD是當前版本，HEAD^ 是上一個版本，HEAD^^是上上個版本，往上第100個版本是HEAD~100.
$ git reset --hard HEAD^
HEAD is now at 31e5220 add distributed
- 此時的readme.txt中已經是add distributed那一版。
想要再恢復到append GPL這一版，可以用git reset --hard 509c3,其中509c3是commit id的前幾位。當不知道這個id但是又想回復到新版本時，使用git reflog命令可以查看每一次的命令, 可以看到append GPL當前的id
$ git reflog
31e5220 (HEAD -> master) HEAD@{0}: reset: moving to HEAD^
509c390 HEAD@{1}: reset: moving to 509c3
31e5220 (HEAD -> master) HEAD@{2}: reset: moving to HEAD^
509c390 HEAD@{3}: commit: append GPL
31e5220 (HEAD -> master) HEAD@{4}: commit: add distributed
f19662e HEAD@{5}: commit (initial): wrote a readme file
