M project5/css/style.css\n\nSo we know the previous version but not the subsequent version of that file.\n\nCould you check again that there is no subsequent version with something like:\n\ngit log --raw --all --full-history -- project5/css/style.css | grep e187557\n\n?\n\n[...]\n\n> 5-here is my problem,how can I looking at those older and newer\n> versions(Could someone point me to which commands I should look at?

The log above showed that the missing\nblob was created on the 15th of December (Sun Dec 15 23:40:39 2013\n+0800). Haven't you pushed your repo somewhere since that day? If you\ndid push, it's probably easier to get the missing blob from where you\npushed.\n\nRegards,\nChristian.\n"}]}
