Command line test for merge conflicts

[diegohb]

How can I simulate a merge from main into a branch for the purpose of knowing if there is or isn't any merge-conflicts (which I plan to persist as a branch attribute) ? It's essentially what happens with automatic merge in teamcity using the plugin but I'd like to not actually perform the merge into main.

 

The merge would typically be 2-5 branches at a time into a single commit (also don't know how to do this via command line) and after some thought, was thinking maybe there's a way to accomplish this into a shelveset at main that would serve as the dry-run of the merge which would also provide the binary output "can all outstanding branches be merged without conflict".
