git-miner mines a commit SHA that has the given prefix.
It does so by inserting a series of invisible spaces at the end of the commit message.
This command produces a new commit object based on the latest commit, such that it has a commit SHA that matches the given prefix:
git-miner --prefix 000000 --threads 8
Output:
Using 8 threads
Computed 31070000 hashes. Effective rate = 0.091 us per hash
Found after 31618507 tries!
Time taken: 2.89 s
Average time per hash: 0.091 us

This commit is now available in the git object database.
If you wish git-miner
to replace the latest commit with this new commit
automatically, you can specify the --amend
flag.
For kicks, this repository has decided to make its commit SHAs be always increasing starting from 0000001 (when viewing just the first 7 bytes, of course). This is the post commit hook:
#!/bin/bash
git-miner --prefix $(printf "%07d" $(git rev-list --count HEAD)) --threads=8 --amend
