为什么 "Here Strings" 被称为 "Here Strings"？
Why are "Here Strings" called "Here Strings"?
这个名字背后的原因是什么？
SS64 解释 PowerShell 中的字符串如下：
A here string is a single-quoted or double-quoted string which can span multiple lines.
Expressions in single-quoted strings are not evaluated.
All the lines in a here-string are interpreted as strings, even though they are not enclosed in quotation marks.
$myHereString = @'
some text with "quotes" and variable names $printthis
some more text
'@
它们在 PowerShell 中有这个名称，因为它是从 Unix 风格的 shell 中借用的，就像 PowerShell 中的许多其他元素和概念一样：
Here documents originate in the Unix shell, and are found in sh, csh, ksh, bash and zsh, among others.
至于为什么最初使用那个名字，文章并没有严格涵盖词源，而是基于这样的描述：
In computing, a here document (here-document, here-text, heredoc, hereis, here-string or here-script) is a file literal or input stream literal: it is a section of a source code file that is treated as if it were a separate file. The term is also used for a form of multiline string literals that use similar syntax, preserving line breaks and other whitespace (including indentation) in the text.
名称的“此处”部分指的是“此处”包含的文件（例如，此时）似乎合乎逻辑。
为了完整起见，值得注意的是 PowerShell 还支持在单引号和双引号 [string] 中直接换行，如下所示：
$myString = 'some text with "quotes" and variable names $printthis
some more text'
这里字符串有用的一个更好的例子是当你需要两种类型的引号时：
$myHereString = @'
some text with "quotes" and variable names $printthis
some more text
and my grandma's soup
'@
如果那只是一个单引号字符串，grandma's 中的 ' 需要转义。
如果它是双引号字符串，您需要转义 " 和 的实例，您需要转义 $如果您不想要变量扩展。
有趣的是：here-strings 的解释方式之间的差异构成了 this demonstration of writing a bash/powershell/win batch polyglot（其内容可以在任何这些环境中执行的脚本）的基础。
