问题描述
例如,第2行写着:0(不带引号)。我想改变这种状况0到1,而无需在文本文件中其他任何变动。
For example, line number 2 reads: "0" (without quotes). I want to change that 0 to a 1, without changing anything else in the text file.
我知道是什么行的值将在,所以我需要知道的是如何的值更改为我指定另一个值。我还必须与字符串,不只是数字相同。
I know what line the values will be on, so all i need to know is how to change that value to another value that I specify. I also will have to to the same with strings, not just numbers.
例如:
从:
4.7
0
check
0
1
0
0
要:
4.7
1
check
0
1
0
0
谢谢!
推荐答案
试试这个:
@ECHO OFF &SETLOCAL
SET "file=file"
SET /a Line#ToSearch=2
SET "Replacement=0"
(FOR /f "tokens=1*delims=:" %%a IN ('findstr /n "^" "%file%"') DO (
SET "Line=%%b"
IF %%a equ %Line#ToSearch% SET "Line=%Replacement%"
SETLOCAL ENABLEDELAYEDEXPANSION
ECHO(!Line!
ENDLOCAL
))>"%file%.new"
TYPE "%file%.new"
注:开始用冒号线这doen't正常工作:
,这可能是如果需要固定
Note: this doen't work properly for lines starting with colons :
, this might be fixed if needed.
