我想知道是否有任何方法可以一次读取一行嵌套的 while 循环中的两个输入文件。例如，假设我有两个文件FileA和FileB.

文件A：

[jaypal:~/Temp] cat filea
this is File A line1
this is File A line2
this is File A line3

文件B：

[jaypal:~/Temp] cat fileb
this is File B line1
this is File B line2
this is File B line3

当前示例脚本：

[jaypal:~/Temp] cat read.sh 
#!/bin/bash
while read lineA
    do echo $lineA 
    while read lineB
        do echo $lineB 
        done < fileb
done < filea

执行：

[jaypal:~/Temp] ./read.sh 
this is File A line1
this is File B …
