bashrc bit to start mergetool on conflict automatically

.bashrc

git() 
{ 
  if [[ $1 == "merge" ]] || [[ $1 == "rebase" ]] || [[ $1 == "pull" ]]; then 
    command git "$@" 
    rc=$?
    if [[ $rc == 1 ]]; then
      echo "There are conflicts, better run git-mergetool!!!"
      # There might be some other condition that returns a '1',
      # if so you can add another check like this:
      # if grep Conflicts $(git --git-dir)/MERGE_MSG;
      command git mergetool
    fi
  else 
    command git "$@"
  fi
}
