如果您的用户支持支持Unicode的终端，则可以执行以下操作:

If your user supports a Unicode-aware terminal, then, you could do something like:

printf '\u2500\u252c\u2500\nf%sO%so\n\u2500\u2534\u2500\n' \
  "$(tput setf red)" "$(tput setf black)"

将 \ u2500 替换为水平条，将 \ u252c 替换为带有向下的三通的水平条，将 \ u2534 带有一个向上的三通的单杠等等.

The \u2500s get replaced with horizontal bars, the \u252c with a horizontal bar with a tee pointing down, the \u2534 with a horizontal bar with a tee pointing up, etc.

将％s s替换为相应的参数-"$(tput setf red)" ，以使前景文本变为红色(或者，如果没有字符，当前的终端不支持彩色)，"$(tput setf black)" ...好吧，明显的事情.

The %ss get replaced with corresponding arguments -- "$(tput setf red)" to make the foreground text red (or no character at all, if the current terminal doesn't support color), the "$(tput setf black)"... well, does the obvious thing.
