批处理脚本中的符号^是什么意思? [英] What does symbol ^ mean in Batch script?

问题描述

在此命令中:

FOR /F %%A IN ('TYPE "%InFile%"^|find /v /c ""')DO SET "Till=%%A"

^是什么意思?

推荐答案

^符号(也称为插入符号或抑扬符)是Batch脚本中的转义字符.使用该字符时，下一个字符将被解释为普通字符.

The ^ symbol (also called caret or circumflex) is an escape character in Batch script. When it is used, the next character is interpreted as an ordinary character.

在脚本中，将TYPE命令的输出写为FIND命令的输入.
如果您没有在|之前使用转义字符^，则|的常规含义是

In your script, the output of the TYPE command to be written as the input to the FIND command.
If you don't use the escape character ^ before the |, then the regular meaning of | is a pipe character.

文档说:

要在使用echo时显示竖线(|)或重定向字符(<或>)，请在竖线或重定向字符之前使用尖号字符(例如^>，^<或^ | ).如果需要使用插入符号(^)，请键入两个(^^).

To display a pipe (|) or redirection character (< or >) when you are using echo, use a caret character immediately before the pipe or redirection character (for example, ^>, ^<, or ^| ). If you need to use the caret character (^), type two (^^).
