Restoring file mtimes with git
Sometimes is useful to restore the modification times from their last commits - i.e. you're creating a tarball, building a static site which depends on mtimes, etc.
Great news is that there's a part of git-tools which does exactly that. It's very like that you have it in your distro repos (i.e.
apt install git-restore-mtime on Debian/Ubuntu).
Now you just need to go into the repository and run it there:
cd my-repo git restore-mtime
If you can't (or don't want) to install additional packages, you can try something like this:
for f in $(git ls-tree -r -t --name-only --full-name) ; do touch -d $(git log --pretty=format:%cI -- "$f") "$f"; done
(we're listing files with
git ls-tree, then calling
touch -d with the formatted result of
git log on every file)
