Git：删除意外添加到存储库的文件。

Posted 2021-02-26

Note that you don't actually need a temporary branch, you can do this with a 'detached HEAD', but you need to take a note of the commit id generated by the git commit --amend step to supply to the git rebase command rather than using the temporary branch name.

# create and check out a temporary branch at the location of the bad merge
git checkout -b tmpfix <sha1-of-merge>
 
# remove the incorrectly added file
git rm somefile.orig
 
# commit the amended merge
git commit --amend
 
# go back to the master branch
git checkout master
 
# replant the master branch onto the corrected merge
git rebase tmpfix
 
# delete the temporary branch
git branch -d tmpfix
