I ran a git pull that ended in a conflict. I resolved the conflict and everything is fine now (I used mergetool also).
git pull
When I commit the resolved file
You can use git commit -i for most cases but in case it doesn't work
git commit -i
You need to do git commit -m "your_merge_message". During a merge conflict you cannot merge one single file so you need to
git commit -m "your_merge_message"
git add your_file.txt
