字符串替换在批处理文件 [英] String replacement in batch file

问题描述

我们可以替换使用下面的命令在批处理文件中的字符串

We can replace strings in a batch file using the following command

set str="jump over the chair"
set str=%str:chair=table%

这些线做工精细，并切换到跳在桌子上串在椅子跳。现在我想用一些变量字符串中替换单词椅子，我不知道该怎么办了。

These lines work fine and change the string "jump over the chair" to "jump over the table". Now I want to replace the word "chair" in the string with some variable and I don't know how to do it.

set word=table
set str="jump over the chair"
??

任何想法？

推荐答案

您可以使用！，但你必须有ENABLEDELAYEDEXPANSION开关设置。

You can use !, but you must have the ENABLEDELAYEDEXPANSION switch set.

setlocal ENABLEDELAYEDEXPANSION
set word=table
set str="jump over the chair"
set str=%str:chair=!word!%
