When I attempt to use git rm --cached
I receive the following error:
error: the following file has staged content different from both the file and the HEAD:
I know that I can circumvent this error with git rm --cached -f <filename>
. But normally when I unstage files with git rm --cached
I do not get this error.
My question is what does it mean that the file has different staged content from the HEAD
.
Typically, you get this status for an item that is "staged and modified", that is: it was modified in the first place, then it was staged and then it was modified again.
This status must be handled with care, otherwise lead to a lot of misconception if you now run a commit, since only staged changes will be committed (yes, even in the same file context, only staged changes will be committed), and not staged changes will be kept in the non-staging area for a future commit (if staged).
There are three places (for changes) worth to be distinguished:
Only the first two matter, when you edit and commit files. Of the two (unstaged vs staged) git status
shows you, what type of change you have.
