这对于拆下整个脚本最后N线

• 计算总行


• 设置线=行 - N，仍然只是加工流水线数

  @echo OFF
SETLOCAL EnableDelayedExpansion套系= 0
FOR / Fdelims ==%%我在（infile.txt）做（
    集/一个线路=行+ 1
）回声行总数：％LINES％
回声。:: N = 5，最后5行会忽略
集/一个LINES =行-5拨打：PrintFirstNLine> output.txt的转到EOF：PrintFirstNLine
设置CUR = 0
FOR / Fdelims ==%%我在（infile.txt）做（
    回声%%我
    ::回声！CUR！ ： ％％一世
    集/一个CUR = CUR + 1
    如果！CUR！==％LINES％转到EOF
）：EOF退出/ B
 

下面电话：PrintFirstNLine＆GT; output.txt的将给出一个外部文件名的输出的 output.txt的的

输出作为样本输入

 ＆LT;＆PROJECT_NAME GT;
＆LT; CBA_Notifier＆GT;

删除最后5号线

更新

How to delete last n lines from file using batch script

I don't have any idea about batch files, I am writing batch file for the first time.

How should I write this batch file?

For Windows7

Try it for

<Project_Name>

    <CBA_Notifier>
        <Common>
        <File>D:\CBA\CBA_Notifier\Project_Name\IPS-Util.jar</File>
        <File>D:\CBA\CBA_Notifier\Project_Name\Notifier.bat</File>
        <File>D:\CBA\CBA_Notifier\Project_Name\Notifier.xml</File>
        <File>D:\CBA\CBA_Notifier\Project_Name\Notifier.jar</File>      
        </Common>

        <Project_Name>
            <File>D:\CBA\CBA_Notifier\IPS-Util.bat</File>
            <File>D:\CBA\CBA_Notifier\IPS-Util.xml</File>
            <File>D:\CBA\CBA_Notifier\*BuildLog.bat</File>
        </Project_Name>
    </CBA_Notifier>
    <CCNET>

This the complete script for remove last N line

• count the total line
• set Line = Line - N , remain just processing lines number

@echo OFF
setlocal EnableDelayedExpansion

set LINES=0
for /f "delims==" %%I in (infile.txt) do (
    set /a LINES=LINES+1    
)

echo Total Lines : %LINES%
echo.

:: n = 5 , last 5 line will ignore 
set /a LINES=LINES-5

call:PrintFirstNLine > output.txt

goto EOF

:PrintFirstNLine
set cur=0
for /f "delims==" %%I in (infile.txt) do (      
    echo %%I        
    ::echo !cur! : %%I      
    set /a cur=cur+1    
    if "!cur!"=="%LINES%" goto EOF
) 

:EOF 

exit /b

Here call:PrintFirstNLine > output.txt will give the output in an external file name as output.txt

Output for sample Input

<Project_Name>      
<CBA_Notifier>      
    <Common>        
    <File>D:\CBA\CBA_Notifier\Project_Name\IPS-Util.jar</File>      
    <File>D:\CBA\CBA_Notifier\Project_Name\Notifier.bat</File>      
    <File>D:\CBA\CBA_Notifier\Project_Name\Notifier.xml</File>      
    <File>D:\CBA\CBA_Notifier\Project_Name\Notifier.jar</File>              
    </Common>       
    <Project_Name>      
        <File>D:\CBA\CBA_Notifier\IPS-Util.bat</File>   

remove last 5 line

Update

:PrintFirstNLine
set cur=0
for /F "tokens=1* delims=]" %%I in ('type "infile.txt" ^| find /V /N ""') do (
   if "%%J"=="" (echo.) else (
        echo.%%J
        set /a cur=cur+1    
        )  

   if "!cur!"=="%LINES%" goto EOF
)
