There are 2 ways to do it: simplified on a single line or not simplified with more details.

Simplified form

$ git log --branches --not --remotes --simplify-by-decoration --decorate --oneline

output:

a0ea499 (HEAD, master) Fix html layout.
49f7b9c (hotfix) Fix javascript validation in contact form.
ff48529 (deletedusers) New model to admin deleted users.

Complete form

Simply remove the following: --oneline

$ git log --branches --not --remotes --simplify-by-decoration --decorate

output:

commit a0ea499... (HEAD, master)

    Fix html layout.

but... is so long write this each time, so... we will create an alias :)

Edit .gitconfig file

[alias]
        unpushed = log --branches --not --remotes --simplify-by-decoration --decorate --oneline

and then...

Use it!

$ git unpushed
