Practice safe-sudo'ing with ssudo. Removes elevated priveleges after a command is run to avoid those accidental shutdowns.

ssudo.sh

# Throw this in your .zshrc (.bashrc may work too)
safe_sudo() {
 cmd="${@: 1}"
 if [ "" = "$cmd" ]; then 
  echo "Missing parameters!";
  return 1
 fi

 sudo ${@: 1};
 sudo -k;
 echo "Sudo permissions removed from this terminal."
}
alias ssudo=safe_sudo
