I want to copy a large SVN repo and hash all committer/author names as they are confidential. I want to maintain the working repo, with all revision and be able to tell each committer apart but with a hashed(or obscured) author name.

So far I have used git-svn to copy the repo to git and I'm looking into using git filter-branch --env-filter to do this. However, it seems more suitable for replacing one specific author rather than all authors (there is likely hundreds). I want to change all of the names without having to enter each one manually into an if statement.

Can anyone give me advice on how to approach this problem? I'm not sure how best to proceed.

The following is the script i'm aware of but which would require manual processing of each author:

I have a repository on bitbucket which is aligned with the online repository (origin), while using Atlassian Sourcetree as tool for managing it.

Let's say it has 20 commits.

Sourcetree for some reason haves its share of fun changing project settings and I wrongly pushed 2 commits (let's say commit 15 and 16 as some other coworker which uses the machine too.

I want to put my name and mail in those commits.

Let's imagine the tree like this (without branches, just master)

Commit number -> comment -> commit id -> author/mail

• 18 -> commit comment blabla -> 29huh23 -> me me@mycompany.com
• 17 -> commit 17 feature XYZ -> abs2881 -> me me@mycompany.com
• 16 -> commit 16 feature KWZ -> anu2716 -> someone other@othercompany.com
• 15 -> commit 15 feature IHZ -> 11suhs2 -> someone other@othercompany.com
• 14 -> commit 14 feature UYZ -> 1uuhw87 -> me me@mycompany.com

someone other@othercompany.com should become me.

I'm admin on the repo.

How to do it in a simple way? It's possible from Sourcetree? Should I do it from the terminal?

Could it be a workable solution to manually modify files in the .git folder and create a new repo and commit there?

Question is not duplicate as suggeste duplicate answers does not work well.

EDIT - CORRECT PROCEDURE FOR ANYONE LOOKING HOW TO DO IT WITHOUT TOO MUCH RESEARCH

Since everyone is marking this as duplicate while is not, as other procedures are INCOMPLETE and leave someone (like me) who is not very cool with git with problems and questions, the correct procedure is:

From SourceTree, launch terminal with the terminal button on top right when the repo is open.

Then paste this and execute, with the substitutions suitable for your case

The question may seem odd, but I have issues syncing git history after rewriting over 100 commits.

On the machine I did rewrite from, a simple git fetch synced it all.

On another mac machine, git sync did not help, but after a random deleting of local .git/ log and refs files and then issuing git pull, history got refreshed.

However, no matter what I do on the Windows machine, I cannot refresh project history. Tried it all:

• git reset --hard HEAD & git fetch
• git fetch --all
• git pull
• etc

Each time on Windows machines, I get duplicated entries (I changed Author fields) of the same commit with a different author.

I followed massive history rewrite using this tutorial:
