## Obliterated AgainDescription:
I realized that the previous command had a mistake. It should be right this time...?
```bash$ git filter-branch --index-filter "git rm -f --ignore-unmatch *flag" --prune-empty -- --all$ git reflog expire --expire=now --all$ git gc --aggressive --prune=now```
Using `git log` and `git show` didn't find anything
I google about "git restore after git filter-branch", I found something in [this link](https://stackoverflow.com/questions/14542326/undo-git-filter-branch)
After running `git reset --hard refs/original/refs/heads/master` command, we get the flag back!```bashroot@2Real:~/Downloads/TSGCTF/Obliterated_again/easy_web# git reset --hard refs/original/refs/heads/masterHEAD is now at 1c80e25 enable production moderoot@2Real:~/Downloads/TSGCTF/Obliterated_again/easy_web# lsproblem  README.mdroot@2Real:~/Downloads/TSGCTF/Obliterated_again/easy_web# cd problem/root@2Real:~/Downloads/TSGCTF/Obliterated_again/easy_web/problem# lsdata.db  flag  lib  main.cr README.md  shard.lock  shard.yml  src```Using the same script:```pythonimport zlibf = open('easy_web/problem/flag')print zlib.decompress(f.read())```
