Shell:

alias cdg='cd "$(git root)"'

~/.gitconfig:

[alias]
  root = rev-parse --show-toplevel

Sadly it is not possible to do so with a git alias, c.f. https://stackoverflow.com/questions/19032372/git-alias-for-shell-command-to-cd-into-git-root-not-working-as-expected:

Your shell is invoking Git, and Git is invoking another shell in which to run your cd command. This command is successful, and this changes the working directory of the child shell, but it does not change the working directory of Git, nor of the parent shell.

In order to do this you need to run the command in your current shell, which means that invoking Git will not be able to accomplish this. You will have to continue using a shell alias.

Since we cannot change directory with a git alias, then at least we can use one to print the repository root.
