whiptail 命令

常用示例

说明

whiptail displays text-based dialog boxes from shell scripts, providing a user-friendly interface for input and selection. It creates ncurses-based dialogs that work in terminal environments, supporting various dialog types including messages, input boxes, menus, and progress bars. Output from input dialogs goes to stderr, requiring file descriptor redirection (3>&1 1>&2 2>&3) to capture in shell variables. Exit codes indicate user choices (0 for OK/Yes, 1 for Cancel/No).
