If you have a setup script add the following to set this automatically:
defaults write com.apple.finder FXDefaultSearchScope -string "SCcf"
I'm interested in what you mean by "setup script" - I assume you have a script of some sort you run when / if you re-install the OS? I'd love to hear more about this!
Look up dotfiles on GitHub - for example https://github.com/mathiasbynens/dotfiles/blob/main/.macos
I added a PR to fix rsync, mosh, and some other tools, since they will be broken out of the box.
But it seems this project has fallen behind on PRs.
If you would like to have this fix, you can do this after cloning the repo:
git clone https://github.com/mathiasbynens/dotfiles && cd dotfiles
git fetch origin "+refs/pull/*/head:refs/remotes/origin/pr/*" && git cherry-pick origin/pr/963
