powershell - 如何在 Powershell 中组合两个列表的每个元素

Question

假设我有两个这样的数组：

$greetings = "hello","hola","namaste"

$names = "jon","jim"

如果我需要这样的输出：

hello jon
hola jon
namaste jon
hello jim
hola jim
namaste jim

我该怎么办？

我试过这个：

$greetings | % { $_ + " " + $names}

这只是给我这样的输出：

hello jon jim
hola jon jim
namaste jon jim

Answer 1

一条线：

$names | % { foreach($greeting in $greetings) { "$greeting $_" }}

Answer 2

你需要一个嵌套循环：

$greetings = "hello","hola","namaste"

$names = "jon","jim"

Foreach ($name in $names)
 {
  Foreach ($greeting in $greetings)
   {
    "$greeting $name"
   }
 }
