How to configure the merge graphical tool on the git command line?

Question

When using git under the command line, merge is very inconvenient. How to configure the graphical tool?

Answer 1

[diff]
  tool = tortoisediff
[difftool]
  prompt = false
[merge]
  tool = tortoisemerge
[mergetool]
  prompt = false
  keepBackup = false

[difftool "tortoisediff"]
cmd = "TortoiseMerge.exe" -mine:"$REMOTE" -base:"$LOCAL"

[mergetool "tortoisemerge"]
cmd = "TortoiseMerge.exe" -base:"$BASE" -theirs:"$REMOTE" -mine:"$LOCAL" -merged:"$MERGED"

It’s really fun to use the command line with tortoisemerge

Answer 2

As long as the system has image operation, there are a lot of GUI Git clients, which can operate Git very conveniently. I recommend one of them: SourceTree, which is full-featured and cross-platform.
