string - 如何在 .txt 中搜索字符串？

Question

我想在 .txt 中搜索一个字符串。

确定行后需要在行尾添加另一个字符串...

请帮忙

例子：

(
echo 3-Trip-7000-23 
echo 6-Lunch-600-2 
echo 7-Breakfast-15-5
) > FILE.txt

如果我键入Lunch它会在这种情况下打印，Lunch-600-2因为在文件中搜索字符串“Lunch”，我该如何编写代码......我在 Windows 中

在顶部设置变量，我这样做是为了自动构建反编​​译框架的 rom

@echo off
setlocal enableextensions enabledelayedexpansion
set search=search for this string
set file=searchfile.txt
set addstring=add this string to the line

set count=0
for /F "usebackq tokens=*" %%A in ("%file%") do (
set /A count+=1
Echo.%%A | findstr /C:"%search%">nul && (set magicnumber=!count!)
)
set count=0
for /F "usebackq tokens=*" %%A in ("%file%") do (
set /A count+=1
if !count! == %magicnumber% echo %%A%addstring% >>tmp.txt
if !count! == %magicnumber% set line=%%A
if not !count! == %magicnumber% echo %%A >>tmp.txt
)
del /Q %file%
ren "tmp.txt" "%file%"
echo "%search%" is on line %magicnumber% and line has been changed to "%line%%addstring%"
