这基本上将文件作为输入(%textfile%)并逐步遍历每一行,用%replace%替换%search%的任何实例。它运作良好,但它正在编写行号。请参阅代码下面的示例i / o。
我在别处找到了这段代码。我认为我在批处理脚本方面相当不错,但我不熟悉什么!正在做。
(for /f "delims=" %%i in ('findstr /n "^" "%textfile%"') do (
set "line=%%i"
setlocal enabledelayedexpansion
set "line=!line:%search%=%replace%!"
echo(!line!
endlocal
))>"%newfile%"
输入文件:
:host {
display: block;
}
/* To ensure your styling works under the Shadow DOM polyfill, see
www.polymer-project.org/docs/polymer/styling.html#directives */
polyfill-next-selector { content: ':host > h2'; }
::content h2 {
color: blue;
}
输出文件:
1::host {
2: display: block;
3:}
4:
5:/* To ensure your styling works under the Shadow DOM polyfill, see
6: www.polymer-project.org/docs/polymer/styling.html#directives */
7:polyfill-next-selector { content: ':host > h2'; }
8:::content h2 {
9: color: blue;
10:}
答案 0 :(得分:1)
这是原因。来自findstr /?
:
/N Prints the line number before each line that matches.
你的命令有:
'findstr /n "^" "%textfile%"'
