Question

我的个人资料中有以下功能定义：

// alias for inner query
MyEntity inner = null;
// this alias is for outer query, and will be used in 
// inner query as a condition in the HAVING clause
MyEntity outer = null;

var minIdSubquery = QueryOver.Of<MyEntity>(() => inner)
    .SelectList(l => l
        .SelectGroup(() => inner.Ref) // here we GROUP BY
        .SelectMin(() => inner.Id)
    )
    // HAVING to get just Min(id) match
    .Where(Restrictions.EqProperty(
      Projections.Min<MyEntity>(i => i.Id),
      Projections.Property(() => outer.Id)
    ));

// outer query
var query = session.QueryOver<MyEntity>(() => outer)
    .WithSubquery
    // we can now use EXISTS, because we applied match in subquery
    .WhereExists(minIdSubquery);

但是当我执行函数function design { Set-Location $env:CC72\Designer .\RunDesigner.bat }时，PowerShell会执行两次批处理RunDesigner.bat并启动它的两个实例：

design

为什么？

批次的内容如下：
PS C:\Users\s3201> design Starting Designer... Starting Designer... PS C:\customer\Designer>

如果我从提到批处理的目录启动Vim，那么它们同时启动 - Vim和批处理文件因此，问题开始时消息的原因很明显 - PowerShell尝试首先启动该批处理，找不到它，写入消息并启动Vim。但为什么它首先尝试启动该批次呢？显然，根本原因在于某些PowerShell定义。哪个？（我检查了别名）。

PowerShell启动批处理两次
