Question

我写了一个小脚本，模拟某人在屏幕上输入用户输入。

只要没有换行符，它就会很好用。我似乎无法弄清楚如何改变我的脚本以使其工作，我知道它必须简单。

如果有人有更好的脚本编写方法，我也愿意进行彻底的重构。

#!/bin/bash
#Displays input as if someone were typing it

read the_input_line

while [ -n "$the_input_line" ]
        do
                printf "%c" "$the_input_line"
                sleep .1
                the_input_line=${the_input_line#?}
done

Answer 1

您的代码只读一行。这会遍历所有行。

#!/bin/bash
#Displays input as if someone were typing it

while read the_input_line
do
  while [ -n "$the_input_line" ]
  do
    printf "%c" "$the_input_line"
    sleep .1
    the_input_line=${the_input_line#?}
  done
  printf "\n"
done
