Finding developers who recently made changes to a component with git

A few git commands to list the developers with recent commits in a specific folder. I find that this is a good/quick way to find out who you need to talk to if you have questions about a specific code component or feature.

chinhdo@ubuntu2:~/v/tmp/converted2$ git shortlog -sn
    10  Chinh Do
     6  cdo
     5  Vas Gábor

Use git log and –pretty to show more columns:

$ git log --after='2020-01-01' --no-merges --abbrev-commit --pretty="format: %h (%an - %cr) - %s" -- .

 ...

List recent authors sorted by number of commits:

$ git log --after='2019-06-01' --no-merges -- . | grep Author: | sort | uniq -c | sort -bgr
       9 Author: George Kalpakas [email protected]
       7 Author: Joey Perrott [email protected]
       3 Author: Paul Gschwendtner [email protected]
       2 Author: Michael Prentice [email protected]
       2 Author: Judy Bogart [email protected]
