在cmd之前的管道前面的正斜杠是做什么去除回声的行尾？ [英] What does a forward slash before a pipe in cmd do to remove the line ending of an echo?

问题描述

此代码：

    @echo off
    echo/|set /p ="Executing backup...."
    echo/|set /p =" backup procedure"

...从回声在同一行，并在cmd窗口中产生以下输出：

... came from Echoing in the same line and produces the below output in a cmd window:

    Executing backup....backup procedure

然而，我似乎没有找到一个解释通过谷歌在正斜线对¿管道？导致 set 的输出为 echo ed code>

However, I cant seem to find an explanation through google on what the forward slash does to the ¿pipe? to cause set's output to be echoed to the console / stdout

如果任何人也可以建议一个好的网站学习更多关于 cmd / <$ c

If anyone could also suggest a good website for learning more about cmd / cmd programs' features like this, it would be appreciated.

推荐答案

护理

1）echo打印set / p = ...的结果，带/不带/之前的管道，所以我不知道你的问题是什么。

1) echo prints the result of set /p =... with or without the / before the pipe, so I'm not sure what your question is asking

2）（它也将打印set / p = ...回声之后随机垃圾，因为它读取管道的东西，而不是它接收的参数。）

2) (It will also print set /p =... with random junk after the echo, too, since it's reading the piped stuff and not the arguments it receives.)

因此，我建议您修改引用的SO职位，以防其他人混淆。

I will hence suggest edits to the referenced SO post, to prevent others confusion.
