Could I change my name and surname in all previous commits?
GitGit Filter-BranchGit Problem Overview
I would like to change my name, surname and email in my all commits, is it possible?
Git Solutions
Solution 1 - Git
Use git-filter-branch
.
git filter-branch --commit-filter 'if [ "$GIT_AUTHOR_NAME" = "Josh Lee" ];
then export GIT_AUTHOR_NAME="Hobo Bob"; export [email protected];
fi; git commit-tree "$@"'
This only affects the author, not the committer (which for most commits will be the same as the author). If you want to rewrite those as well, set the GIT_COMMITTER_NAME
and GIT_COMMITTER_EMAIL
variables.
The standard warning about rewriting history applies; only do it to history that has not yet been shared.
June 2018 Update
The manual now includes a solution, using --env-filter
, in its examples: https://git-scm.com/docs/git-filter-branch#_examples :
git filter-branch --env-filter '
if test "$GIT_AUTHOR_EMAIL" = "root@localhost"
then
GIT_AUTHOR_EMAIL[email protected]
fi
if test "$GIT_COMMITTER_EMAIL" = "root@localhost"
then
GIT_COMMITTER_EMAIL[email protected]
fi
' -- --all
Solution 2 - Git
To rewrite both author and commiter in all selected commits:
git filter-branch --commit-filter \
'if [ "$GIT_AUTHOR_NAME" = "OldAuthor Name" ]; then \
export GIT_AUTHOR_NAME="Author Name";\
export GIT_AUTHOR_EMAIL[email protected];\
export GIT_COMMITTER_NAME="Commmiter Name";\
export GIT_COMMITTER_EMAIL[email protected];\
fi;\
git commit-tree "$@"'
Solution 3 - Git
If there are no other authors, you can do:
git filter-branch --commit-filter 'export GIT_AUTHOR_NAME="authorname"; \
export GIT_AUTHOR_EMAIL[email protected]; git commit-tree "$@"'
Solution 4 - Git
Save the script below as e.g. ~/.bin/git-replace-author
and run it using, e.g:
git replace-author "John Ssmith" "John Smith" "[email protected]"
With no arguments, it updates all commits with your name to use your current email address according to Git config.
DEFAULT_NAME="$(git config user.name)"
DEFAULT_EMAIL="$(git config user.email)"
export OLD_NAME="${1:-$DEFAULT_NAME}"
export NEW_NAME="${2:-$DEFAULT_NAME}"
export NEW_EMAIL="${3:-$DEFAULT_EMAIL}"
echo "Old:" $OLD_NAME "<*>"
echo "New:" "$NEW_NAME <$NEW_EMAIL>"
echo "To undo, use: git reset $(git rev-parse HEAD)"
git filter-branch --env-filter \
'if [ "$GIT_AUTHOR_NAME" = "${OLD_NAME}" ]; then
export GIT_AUTHOR_NAME="${NEW_NAME}"
export GIT_AUTHOR_EMAIL="${NEW_EMAIL}"
export GIT_COMMITTER_NAME="${NEW_NAME}"
export GIT_COMMITTER_EMAIL="${NEW_EMAIL}"
fi'

Solution 5 - Git
Only if you haven't pushed your commits to the world. Other wise everyone else has your old name in their repo which is unlikely you can change everyone's.
Solution 6 - Git
With Git 2.24 (Q4 2019), git filter-branch
(and BFG) is deprecated.
The equivalent would be, using newren/git-filter-repo
, and its example section:
cd repo
git filter-repo --mailmap my-mailmap
with my-mailmap
:
Correct Name <correct@email.com> <old@email.com>
That would replace the author name and email of any commit done by anyone with <[email protected]>
