问题
I am using git to track a large LaTeX document which I write using Kile on different machines.
Kile writes to its .kilepr config file when closing Kile. The problem I often run into is that I commit before closing Kile. So I commit and push, work on the other machine, and when I come back and want to pull I get a merge conflict because the .kilepr file contains the cursor position (which obviously changed now).
My question: Is there a way to add a merge rule to git config for a specific file (always use --theirs)? Using .gitignore is not an option since the .kilepr file contains important information such as files in the project.
回答1:
All possible ways to simulate a merge -s theirs are listed in "git command for making one branch like another".
But for one file, all you need is a merge driver, declared in a .gitattributes file, with a keepTheir script like:
mv -f $3 $2
exit 0
See "“git merge -s theirs” needed — but I know it doesn't exist" for a concrete example of a custom merge driver (including my own version).

2018 solution: Merge Drivers
In git config you can add custom merge drivers:
[merge "my-custom-driver"]
name = A custom merge driver used to resolve conflicts in certain files
driver = my-merge-tool.sh %O %A %B
but you can also just return 'true' for the driver which will always keep local changes:
[merge "keep-local-changes"]
name = A custom merge driver which always keeps the local changes
driver = true
Then in .gitattributes you can define which file types use which custom merge drivers:
/folder/**/*.fileExtension merge=keep-local-changes
