bash腳本中的換行解釋

Question

我寫了一個小腳本來模擬某人在屏幕上輸入用戶輸入。

只要沒有換行符，它效果很好。我似乎無法弄清楚如何改變我的腳本來完成這項工作，而且我知道它必須簡單。

如果有人有更好的腳本編寫方式，我也可以進行完整的重構。

#!/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

您的代碼只讀取一行。這遍歷所有行。

#!/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
