Git merge with data modified in one branch and nothing done in other branch

If we merge two branches such that in one branch I edit the whole file from start to end and in other branches, I do not change anything left the original content then what will be the final content of the file when I merge both branches?

Solution

The answer is probably it depends. It depends mostly on the shared parent of the 2 branches. And more things may get involved based on the merge strategy Git lands on.

The most likely answer will be:

Git will check the common parent where the file is still present.
Git will see that the file was deleted after branch created.
Git will merge with the branches and leave the file deleted.
