bash - 如何从 bash 中读取整行

Question

我有一个文件file.txt，内容如下

i love this world

I hate stupid managers
I love linux

I have MS

当我执行以下操作时:

for line in `cat file.txt`; do
echo $line
done

输出类似

I
love
this
world
I
..
..

但我需要像下面这样整行的输出——有什么想法吗？

i love this world

I hate stupid managers
I love linux

I have MS

Answer 1

while read -r line; do echo "$line"; done < file.txt
