Git change name or email in commit history
This is brilliant: Git, rewrite previous commit usernames and emails - Stack Overflow
TL;DR
git config --global alias.change-commits '!'"f() { VAR=\$1; OLD=\$2; NEW=\$3; shift 3; git filter-branch --env-filter \"if \\\"\$\`echo \$VAR\`\\\" = '\$OLD' ; then export \$VAR='\$NEW'; fi\" \$@; }; f"
Then
git change-commits GIT_AUTHOR_NAME "old name" "new name"
# last 10 commits
git change-commits GIT_AUTHOR_EMAIL "old@email.com" "new@email.com" HEAD~10..HEAD
Depending on why I need this, I may need also GIT_COMMITTER_[NAME/EMAIL]
For multiple times, I created an change-commit-f that forces overwiriting the backup:
git config --global alias.change-commits-f '!'"f() { VAR=\$1; OLD=\$2; NEW=\$3; shift 3; git filter-branch -f --env-filter \"if \\\"\$\`echo \$VAR\`\\\" = '\$OLD' ; then export \$VAR='\$NEW'; fi\" \$@; }; f"
A quick tldr from other answer, may be better but untested:
git config alias.change-commits '!'"f() { VAR=\$1; OLD=\$2; NEW=\$3; shift 3; git filter-branch --env-filter \"if \\\"\$\`echo \$VAR\`\\\" = '\$OLD' ; then export \$VAR='\$NEW'; fi\" \$@; }; f "
git change-commits GIT_AUTHOR_NAME "<Old Name>" "<New Name>" -f
git change-commits GIT_AUTHOR_EMAIL <old@email.com> <new@email.com> -f
git change-commits GIT_COMMITTER_NAME "<Old Name>" "<New Name>" -f
git change-commits GIT_COMMITTER_EMAIL <old@email.com> <new@email.com> -f

Nel mezzo del deserto posso dire tutto quello che voglio.
