bash - 使用 tput rc 时如何清除读取输入？

Question

$ cat test.sh
#!/bin/bash

sc=$(tput sc)
rc=$(tput rc)

printf "$sc%s\n" "Type word"
read -r word
printf "$rc%s\n" "Type word (again)"
read -r word_confirmation

$ ./test.sh
Type word (again)
test

我想test被清除。

tput ed将屏幕从当前光标位置清除到屏幕末尾（在 macOS 上中断，请参阅此答案）。

#!/bin/bash

tput sc
printf "%s\n" "Type word"
read -r word
tput rc
tput ed
printf "%s\n" "Type word (again)"
read -r word_confirmation

tput清屏
