推荐答案
我认为问题是您正在从重定向的STDIN中读取(因为您< file.txt)
I think the problem is you are reading from a redirected STDIN (because you <file.txt)
$ perl -e 'system("stty -echo");' </tmp/foo
stty: standard input: Inappropriate ioctl for device
您可能应该将文件作为参数传递给脚本.
You should probably pass your file as a parameter to your script.
