How to find the number of files changed from one commit to another in git

Question

I am working on a git repository which contains huge number of files changed b/w one commit to another, how to extract the number of files changes b/w commits.

Answer 1

git show --stat

This gives the list of files changed like this:

1 file changed, 1 insertion(+), 1 deletion(-)

Optionally you can add the commit code if you don't want to get the information from the latest.

git show --stat {commit code without brackets}

Answer 2

Apart from the above listed methods you can do this too:

git diff HEAD^..HEAD --name-only - will give the list of files changed between HEAD and one revision before HEAD (HEAD^). You can replace HEAD^ with a SHA1 of the "from" commit and HEAD with the SHA1 of the "to" commit:

git diff <SHA1-of-from-commit>..<SHA1-of-to-commit> --name-only

So if you pipe the output to wc -l it should give you the number of files changed between commits.

Answer 3

In windows:

git whatchanged -1 --format=oneline | find /v /c ""

The important windows-specific piece is that you must replace the wc command used in other solutions with this:

  | find /v /c ""

Answer 4

use this:

git log --oneline --name-status <HASH> -1

eg:

$ git log --oneline --name-status bb3ae49 -1
M       .vim/spell/en.utf-8.add
M       .vim/spell/en.utf-8.add.spl

this works just like

git whatchanged --oneline --name-status <HASH> -1

Answer 5

EDIT: "this will always count the files plus one, cause the --format=oneline includes the commit-hash/header" as mentioned by c00kiemon5ter

The git whatchanged tool shows you a summary of files that were modified. By itself it lists all commits, but you can also limit it to just the recent n commits:

git whatchanged -1

To count files:

git whatchanged -1 --format=oneline | wc -l

See git help whatchanged for details.
