现有字符串

 "真好呀!!!"

如何替换成 "真好呀@@@" 这是我的测试代码:

setlocal  ENABLEDELAYEDEXPANSION
for /f %%a in (1.txt) do (
set str=%%a
set str=!str:^!=@!
echo !str!
pause)

set /? Environment variable substitution has been enhanced as follows: %PATH:str1=str2% would expand the PATH environment variable, substituting each occurrence of "str1" in the expanded result with "str2". "str2" can be the empty string to effectively delete all occurrences of "str1" from the expanded output. "str1" can begin with an asterisk, in which case it will match everything from the beginning of the expanded output to the first occurrence of the remaining portion of str1.

多谢了为什么我直接在CMD窗口中行的如果该字符串是在文本中,我用FOR去读取,再替换,怎么不成??

认真看了一下,学了不少! 有些地方还是不太懂!! 但测试来测试去,还是不得解,这代码到底该怎么写呀?

for /f %%a in (1.txt) do ( set "str=%%a" setlocal ENABLEDELAYEDEXPANSION set str=!str:^!=@! echo !str! pause) [ Last edited by lqh123108 on 2008-12-25 at 22:44 ]

@echo off
for /f "delims=" %%a in ('more +7^<%~fs0') do (
  set "str=%%a"
  call set "str=%%str:!=@%%"
  call echo.%%str%%
)
pause>nul&goto :eof
"真好呀!!!"

多谢猫兄的指点

谢了针对文件通过! OK! for /f "delims=" %%a in (1.txt) do ( set "str=%%a" call set "str=%%str:!=@%%" call echo.%%str%% ) pause>nul&goto :eof 看来,文本中的感叹号的替换不能启用变量延迟,而应该使用跳出循环的办法,防止歧义!
