git-vanity-commit

This tool finds commit hash prefixes. It does this by appending a commit header with a number, incremented until the given hash prefix is found. Without either of -reset or -write specified, nothing is written to the repository.

Installation

go install github.com/jsageryd/git-vanity-commit@latest

Usage

$ git-vanity-commit -h
Usage of git-vanity-commit:
  -commit string
        Starting point (default "HEAD")
  -key string
        Key used in the commit header (defaults to the prefix)
  -prefix string
        Desired hash prefix (mandatory)
  -print
        Print the commit hash found to stdout
  -quiet
        Suppress log output
  -reset
        If set, reset to the new commit (implies -write)
  -start int
        Iteration to start from
  -write
        If set, write the new commit to the repository (hash-object -w)
