Predict git commit id and commit a file which contains that commit id
git
Solution
That is cryptographically impossible.
The git commit ID is an SHA1 hash of the contents of the commit. Any change you make in the commit will also affect the ID.
Problem
How to do something like this: Create a with following content: $ cat testfile.txt This file will be committed with this id: 83b90a07620ef578450c40a6d38bacc42de7ad2d Commit testfile.txt $ git add testfile.txt $ git commit -m 'Thank you' Execute git log to verify predicted commit id: $ git log commit 83b90a07620ef578450c40a6d38bacc42de7ad2d Author: rohit01 <*@gmail.com> Date: Fri Feb 21 23:46:52 2014 +0530 Basically, predict the next git commit id and commit a file which contains that commit id.
