批处理文件删除前3行文本文件 [英] Batch file to delete first 3 lines of a text file

问题描述

正如标题状态，我需要一个批处理文件删除前3行中的文本文件。

As the title states I need a batch file to delete the FIRST 3 lines of a text file.

例如：

A    
B    
C    
D    
E   
F    
G

在这个例子中，我需要A，B和C线沿线删除

in this example I need A,B and C deleted along with the line

推荐答案

这应该这样做。

for /f "skip=3 delims=*" %%a in (C:\file.txt) do (
echo %%a >>C:\newfile.txt    
)
xcopy C:\newfile.txt C:\file.txt /y
del C:\newfile.txt /f /q

这将重新创建与前3行中删除的文件。

That will re-create the file with the first 3 lines removed.

要保持更新，你可以在命令提示符下在VBScript样式或输出消息批处理文件整合消息的用户。

To keep the user updated you could integrate messages in the batch file in vbscript style or output messages in the command prompt.

@echo off
echo Removing...
for /f "skip=3 delims=*" %%a in (C:\file.txt) do (
echo %%a >>C:\newfile.txt
) >nul
echo Lines removed, rebuilding file...
xcopy C:\newfile.txt C:\file.txt /y >nul
echo File rebuilt, removing temporary files
del C:\newfile.txt /f /q >nul
msg * Done!
exit >nul

希望这有助于。
