How to find a component with the most commits?

Question

As a tester, in the past, I was often able to find a defect-prone component in our system but looking for those which were often changed. In SVN, I knew how to do it but in GitHub, I cannot seem to find the way.

Answer 1

As mentioned in "Finding most changed files in Git", you do have the git-extras/git-effort or git-most scripts (which, if it is in your PATH, you can call with git effort or git most, like any git-xxx script).
But you need to clone the GitHub repo first.

Example:

C:\Users\vonc\data\git\git>git most
......... [wait a long time] .........
1585    Makefile
1060    cache.h
748     gitweb/gitweb.perl
730     refs/files-backend.c
714     diff.c
670     Documentation/config.txt
659     refs.c
624     git-svn.perl
600     sha1_file.c
517     contrib/completion/git-completion.bash
501     builtin/apply.c
499     Documentation/git.txt
491     GIT-VERSION-GEN
433     git-p4.py
413     git.c
407     builtin/pack-objects.c
401     revision.c
376     builtin/commit.c
336     merge-recursive.c
...

That doesn't translate directly to GitHub, where you have the statistics API, focused on the number of changes, not the actual list of files.
