How to find which files have not changed since commit?

Question

In git, how can one find out which files in directory have NOT changed since some commit?

Answer 1

IMO a far easier way to generate your list would be the following command chain:

git ls-files --full-name | grep -v "$(git diff --name-only <REF>)"

Where <REF> is the hash of the commit from which you want the unchanged files since.

---

git ls-files list, as you could expect, all versioned files and then you grep all files which aren't in the list of changed files since the specified commit.

Answer 2

Use git diff --name-only $REV to get the list of files that have changed. Use git -C $(git rev-parse --show-toplevel) ls-tree -r HEAD --name-only to get the list of all files. Use grep to separate the sets:

git diff ${REV?must specify a REV} --name-only > /tmp/list
git -C $(git rev-parse --show-toplevel) ls-tree -r HEAD  --name-only |
     grep -f /tmp/list -v

Prior to executing those commands, you'll need to specify a rev in the variable REV. eg, REV=HEAD~6 or REV=branch-name~~
