When I first heard some countries did this it was like 20 years ago. I thought at the time it was news because they’d stopped - clearly I was wrong :/

I forsee a requirement that only “approved” OS are allowed to connect to mobile networks, citing security issues.

git() {
  if [ "$1" = "cd" ]; then
    shift
    cd "./$(command git rev-parse --show-cdup)$*"
  else
    command git "$@"
  fi
}

This lets you run git cd to go to the root of your repo, or git cd foo/bar to go to a path relative to that root. You can’t do it as an alias because it’s conditional, and you can’t do it as a git-cd command because that wouldn’t affect the current shell.
