Try a git reset HEAD yourFile, instead of a git rm --cached.
A mixed reset will remove your file from the index, without removing it from the working tree.
See "Undo 'git add' before commit".
In your case, a git stash would need to precede the git reset, and then a git stash pop would restore your changes in progress, after the reset.
Regarding the 'deleted' status after a git rm --cached, that command registers in the index the deletion of the file, which is why you see it recorded as 'deleted' for the next commit.
The OP Ferpega insists:
I am asking why the deleted status is there as resulting of git rm --cached because this command should has the same behavior than git reset HEAD <file> as you can see in git rm.
Well, no, a git rm has not the same behavior as a [git reset][8].
Both will affect the index, but:
- one (the
git rm) will record a file for deletion on the next commit, hence the 'deleted' status,
- the other (
git reset) will copy HEAD to the index, resetting said index back to what the file was in HEAD.
