When a script performs privileged or security-sensitive actions (e.g., deleting/installing application files in system directories), explicitly enforce the required authorization before proceeding. In shell scripts, gate the privileged logic with an effective-UID check (root/admin), and only show the “admin password required” message when the check fails (typically exit afterward). ```sh # Example pattern for privileged scripts if [ "$EUID" -ne 0 ]; then echo "This script requires administrator (root) privileges to remove the application files from system directories." exit 1 fi # Privileged operations go here # rm -rf /system/path/... ``` This prevents partial execution and reduces security risk by ensuring unauthorized users can’t reach code paths that modify protected locations.
