обобщить вывод git log (Summarize 'git log' output)
Описание (Description)
Summarizes git log output in a format suitable for inclusion in
release announcements. Each commit will be grouped by author and
title.
Additionally, "[PATCH]" will be stripped from the commit
description.
If no revisions are passed on the command line and either
standard input is not a terminal or there is no current branch,
git shortlog will output a summary of the log read from standard
input, without reference to the current repository.
