推荐答案
读
从默认的标准输入,它被重定向到文件读取,因此它得到线从该文件。你可以回重定向到终端:
read
reads from standard input by default, which is redirected to the file, so it's getting the line from the file. You can redirect back to the terminal:
read -p "Press Enter to continue" </dev/tty
另一种选择是使用不同的FD的文件重定向
Another option would be to use a different FD for the file redirection
while read -u 3
do
...
done 3< test.txt
