[文本处理] 如何替换掉指定字符串之后的内容？

hjh22222

例如文件A.txt内容有多行，其中有三行分别为:

CurrentGroup=AAAA
CurrentServer=BBBB
CurrentLine=CCCC
AAAA、BBBB、CCCC内容及长度都不固定，
如何把CurrentGroup=    CurrentServer=    CurrentLine=这三个字符串后的不固定内容分别替换成EEE、FFF、GGG

求高手指点一下，万分感谢！！！

找资料学正则表达式。

@echo off
(for /f "delims=" %%a in ('type "A.txt"^|findstr /n .*') do (
	set "str=%%a"
	setlocal enabledelayedexpansion
	set "str=!str:*:=!"
	if "!str:~0,13!"=="CurrentGroup=" (
		echo CurrentGroup=EEE
	) else (
		if "!str:~0,14!"=="CurrentServer=" (
			echo CurrentServer=FFF
		) else (
			if "!str:~0,12!"=="CurrentLine=" (
				echo CurrentLine=GGG
			) else (
				echo;!str!
			)
		)
	)
	endlocal
))>$
move $ A.txt

第三方

sed -i -r -e "s/^([ \t]*CurrentGroup=).+/\1eee/;s/^([ \t]*CurrentServer=).+/\1fff/;s/^([ \t]*CurrentLine=).+/\1ggg/" a.txt

CrLf

暴力解1：

@echo off
for /f "delims==" %%a in ('set') do set "%%a="

set CurrentGroup=AAAA
set CurrentServer=BBBB
set CurrentLine=CCCC

(for /f "delims=" %%a in (a.txt) do (
   for /f "delims==" %%b in ("%%a") do (
      if defined #%%b (set %%b) else echo %%a
   )
))>b.txt
pause
复制代码

暴力解2：

@echo off

(for /f "tokens=1* delims==" %%a in (a.txt) do (
	set "name=%%b"
	set "%%a=%%b"

	set CurrentGroup=AAAA
	set CurrentServer=BBBB
	set CurrentLine=CCCC

	setlocal enabledelayedexpansion
	echo !name!=!%%a!
	endlocal
))>b.txt
pause
