把字符串 “c:/test/1” 中的 “/” 全部替换成 “//” 的原理:
(假设 "C:/TEST/1” 字符串已存在 VAR 变量中:)
C:/WINDOWS>set "var=C:/TEST/1"
(将 var 变量中的字符串里 "/" 字符全部替换成 "//")
C:/WINDOWS>set "var=%var:/=//%"
(显示 var 变量中的内容)
C:/WINDOWS>echo %var%
C://TEST//1
结果为:C://TEST//1 ,已全部替换完成。
下面给几个其他网友给的例子
文件字符串替换
@echo off
echo ***** Replace "abcd" as "ABCD" *****
set strFilePath=C:\Users\Leez\Desktop\TestBat\TestSource.txt
set strOld=abcd
set strNew=ABCD
setlocal enabledelayedexpansion
for /f "tokens=*" %%i in (%strFilePath%) do (
set "var=%%i"
if not !var!.==. (
set "var=!var:%strOld%=%strNew%!"
echo !var!!>>%strFilePath%.bk
)
)
move /y %strFilePath%.bk %strFilePath%
pause
例子二:
@echo off
setlocal enabledelayedexpansion
set file=
set /p file= 请输入要操作的文件名称(包括扩展名):
set "file=%file:"=%"
for %%i in ("%file%") do set file=%%~fi
echo.
set replaced=
set /p replaced= 请输入即将被替换的内容:
echo.
set all=
set /p all= 请输入替换字符串:
for /f "delims=" %%i in ('type "%file%"') do (
set str=%%i
set "str=!str:%replaced%=%all%!"
echo !str!>>"%file%"_tmp.txt
)
copy "%file%" "%file%"_bak.txt >nul 2>nul
move "%file%"_tmp.txt "%file%"
start "" "%file%"
笔者将它更改一下
把16改为17
@echo off
setlocal enabledelayedexpansion
set file=c:\Program Files\hndsclient\ds\GetFile.ini
set "file=%file:"=%"
for %%i in ("%file%") do set file=%%~fi
echo.
set replaced=16
echo.
set all=17
for /f "delims=" %%i in ('type "%file%"') do (
set str=%%i
set "str=!str:%replaced%=%all%!"
echo !str!>>"%file%"_tmp.txt
)
copy "%file%" "%file%"_bak.txt >nul 2>nul
move "%file%"_tmp.txt "%file%"
start "" "%file%"
