Using p4merge to resolve conflicts

When you run into a conflict when merging simply run:

$ git mergetool
  • You will be prompted to run "p4mergetool", hit enter and the visual merge editor will launch.
  • Using the merge tool you can resolve the conflict and then save the file.
  • After you exit the merge tool take a look back at your terminal. You will be asked if the merge was successful, choose yes if all is well or no if you need to start over.
  • This prompting is happening because the "trustExitCode" option is turned off. Personally I always like to be asked, but you can have git just trust the exit code from the merge tool.
