Bash Shell脚本，三组名称，每个组合

我正在尝试编写一个shell脚本，它包含三个名称列表，并从列表中找出每个组合，每个列表上可能有不同数量的名称

列表1
迈克
汤姆
哈利
史蒂夫

列表2
黛博拉
莎拉
珍妮弗

列表3
亚历克斯
乔
凯利
阿曼达
将
菲利普
大卫

它将从列表1中选择Mike，然后从列表2中选择Deborah，然后从列表3中选择所有的名字。然后是列表1中的迈克，列表2中的莎拉，然后是列表3中的所有名字，等等，直到找到所有可能的组合

在思考如何完成此任务时遇到一些困难，如有任何帮助，我们将不胜感激。

您可以使用for循环。设f1、f2和f3为包含三个列表的文件。然后：

for a in `cat f1`;do
 for b in `cat f2`;do
  for c in `cat f3`;do
   echo $a $b $c;
  done;
 done;
done

例如：

$ cat f1
red
green
cat

$ cat f2
rice
bread
cat f

$ cat f3
tomato
onion


$ for a in `cat f1`;do for b in `cat f2`;do for c in `cat f3`;do echo $a $b $c; done; done; done
red rice tomato
red rice onion
red bread tomato
red bread onion
green rice tomato
green rice onion
green bread tomato

根据存储列表x的方式，您可以简单地使用大括号扩展将所有三个列表排列在一起，例如：

printf "%s\n" {Mike,Tom,Harry,Steve}\
{Deborah,Sarah,Jennifer}\
{Alex,Joe,Kelly,Amanda,Will,Phillip,David}

如果您无法控制脚本本身中的列表，则循环解决方案可以正常工作。

您尝试了什么？你犯了什么错误？列表存储在哪里？您尝试了什么？你犯了什么错误？列表存储在哪里？这非常有效。特别选择这个，因为我以前使用过循环，所以我理解它。这非常有效。特别选择这个，因为我以前使用过循环，所以我理解它。
