如何在 Swift 中获得标准输入/输出/错误的“管道”？

Question

When using Process in Swift, if you do not specify the .standardInput , .standardOutput , or .standardError properties, the Process inherits the standard input/output/error of the caller, which can be quite useful. But let's say that, for example, I want to tell a Process to send its output to the inherited standard error. It seems to me I would want to do something like process.standardOutput = ProcessInfo.processInfo.standardError , but ProcessInfo has no standardError property. How am I supposed to do something like this?

Of course I find the answer to this immediately after posting this question.

The desired objects are FileHandle.standardInput , FileHandle.standardOutput , and FileHandle.standardError .
