How can I view the branch history and check the current branch status using Git commands in the VSCode terminal?

I would like to know the Git commands to:

1. View the commit history of the current branch.
2. Check the current branch status (which branch you’re on and if it’s ahead/behind the remote).
3. List all merged branches.

I’ve used basic Git commands like git log and git status, but I need more detailed information, specifically a concise and formatted view of the branch history.
