My cheat codes
To find the first commit in a branch that is not present in the parent of the branch (i.e., the first unique commit in the branch), you can use the following command:
git log --graph --oneline --boundary <branch> ^<branch>^@ --pretty='%C(cyan)%ad %C(yellow)%h %C(cyan)%d %Creset%s'Replace with the name of your branch. This command utilizes the --boundary option to display commits that are in the branch but not in the parent of the branch. The ^ symbol is used to negate the commit (indicating "not in the parent"), and ^@ represents all reachable commits from the specified commit. This will provide a graphical visualization and a summarized list of commits that are unique to the branch, showing the first commit different from the branch's parent.
A -- E - F - G master - B - C - D fix
git log master..fix B C D
git log master...fixB C D and E F G
git <orig>..<dest> --graph --date-order --pretty='%C(cyan)%ad %C(yellow)%h %C(cyan)%d %Creset%s'
