CONFLICT (add/add): Merge conflict in middle.txt
Auto-merging middle.txt
error: could not apply db8237b... Added middle
Resolve all conflicts manually, mark them as resolved with
"git add/rm <conflicted_files>", then run "git rebase --continue".
You can instead skip this commit: run "git rebase --skip".
To abort and get back to the state before "git rebase", run "git rebase --abort".
Could not apply db8237b... Added middle
sahan@sahan-Lenovo-YOGA-C930-ubuntu:test$ git status
interactive rebase in progress; onto d237400
Last command done (1 command done):
   pick db8237b Added middle
No commands remaining.
You are currently rebasing branch 'master' on 'd237400'.
  (fix conflicts and then run "git rebase --continue")
  (use "git rebase --skip" to skip this patch)
  (use "git rebase --abort" to check out the original branch)

Unmerged paths:
  (use "git restore --staged <file>..." to unstage)
  (use "git add <file>..." to mark resolution)
	both added:      middle.txt

no changes added to commit (use "git add" and/or "git commit -a")
