git: change one line in file for the complete history
When I started my git repo I commited a few files as initial commit to it. Now, many commits later, I noticed that I included in those files a line with information which I do not want to publish (unlike the rest of the code). So I want to remove/change this one line and keep the rest of the code.
Searching around I found this solution: Insert an empty commit as initial commit (described here: Insert a commit before the root commit in Git?), do a rebase on it and then edit the old first commit via amend. Unfortunately, many cruel merge conflicts arise during rebase (as described here: git: solving conflicts caused by rebase).
- How to find out what causes file permissions to change when checking out files with git?
- Git - how to fix child branch after parent rebase
- how to log out of one Github account and use another account?
- svn to git conversion (how to check the repository quality)
- GitHub - prevent collaborators from using push -f
- Curl Initialization error with git pre-push hook
Is there a different way to solve my problem or do have to rebase and edit all conflicts by hand?
Thanks in advance 🙂

Here’s a command that will remove an offending line from a file’s history in all your branches:
git filter-branch --tree-filter 'sed -i "/sensitive information/ d" filename' -- --all
This checks out every revision, runs the
sed command on it, then commits that revision back.
sed command in this case matches any lines containing the pattern
sensitive information in the file named
filename and deletes those lines.
Note: it’s good if you have a backup, and try the
sed script on its own first to make sure it’s doing what you want, because it can take quite a while to run on a long history.
I made this command that doesn’t error out when a file doesn’t exist:
filename=./path/to/your/filename filter=your_regex_here git filter-branch --tree-filter 'test -f $filename && sed -i.bak "/$filter/d" $filename || echo “skipping file“' -- --all
