如何从文件中逐行读取并执行内部内容

Question

如何逐行读取文件中的内容并执行该行的一部分

例如，我的文件中有以下内容

Hello world $(echo 9923,3443,434,344 | cut -d"," -f4)
Hello world $(echo 9923,3443,434,344 | cut -d"," -f2)
Hello world $(echo 9923,3443,434,344 | cut -d"," -f1)

我的预期结果将是

Hello world 344
Hello world 3443
Hello world 9223

我得到的是通过while循环回显

Hello world $(echo 9923,3443,434,344 | cut -d"," -f4)
Hello world $(echo 9923,3443,434,344 | cut -d"," -f2)
Hello world $(echo 9923,3443,434,344 | cut -d"," -f1)

我的代码将类似于

while read LINE
do
     echo $LINE
done < FILE

我尝试了几个东西，比如使用反引号，双引号，eval似乎没什么用。

试试这个：

while read line; do
    eval "echo $line";
done < FILE
