bash脚本中的换行解释

Question

我写了一个小脚本来模拟某人在屏幕上输入用户输入。

只要没有换行符，它效果很好。我似乎无法弄清楚如何改变我的脚本来完成这项工作，而且我知道它必须简单。

如果有人有更好的脚本编写方式，我也可以进行完整的重构。

#!/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

您的代码只读取一行。这遍历所有行。

#!/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
