Export only modified and added files with folder structure in Git

Issue

I would like to get a list of modified and added files in an specific commit so that I can export them and generate a package with the file structure.

The idea is to get the package and extract it on the server. For many reasons I can’t create a hook to pull the repo automatically and the easiest way I have to keep the server updated is generating this package.

Solution

git diff-tree -r --no-commit-id --name-only --diff-filter=ACMRT $commit_id

1. git diff-tree -r $commit_id:

   Take a diff of the given commit to its parent(s) (including all subdirectories, not just the top directory).

2. --no-commit-id --name-only:

   Do not output the commit SHA1. Output only the names of the affected files instead of a full diff.

3. --diff-filter=ACMRT:

   Only show files added, copied, modified, renamed or that had their type changed (eg. file → symlink) in this commit. This leaves out deleted files.

UPDATE FROM THE COMMENT:
Base on the question context and the comments below, with the following command, you can get the ACMRT files as a .tar file with their folder structure.

git diff-tree -r --no-commit-id --name-only --diff-filter=ACMRT $commit_id | tar -czf file.tgz -T -
