具有数值变量的循环的正确格式是

for /l %%i in (startNumber, counter, endNumber) do echo %%i

抽取随机的文本行

@echo off

:: Get time (alas, it's only HH:MM xM

for /f %%a in ('time /t') do set zD1=%%a



:: Get last digit of MM

set zD2=%zD1:~4,1%



:: Seed the randomizer, if needed

if not defined zNUM1 set /a zNUM1=%zD2%


:: Get a kinda random number

set /a zNUM1=zNUM1 * 214013 + 2531011

set /a zNUM2=zNUM1 ^>^> 16 ^& 0x7fff


:: Pull off the first digit

:: (Last digit would be better, but it's late, and I'm tired)

set zIDX=%zNUM2:~0,1%


:: Map it down to 0-3

set /a zIDX=zIDX/3


:: Finally, we can set do some proper initialization

set /a zIIDX=0

set zLO=

set zLL=""


:: Step through each line in the file, looking for line zIDX

for /f "delims=@" %%a in (c:\lines.txt) do call :zoo  %zIDX%  %%a


:: If line zIDX wasn't found, we'll settle for zee LastLine

if "%zLO%"=="" set zLO=%zLL%

goto awdun


:: See if the current line is line zIDX

:zoo


:: Save string of all parms

set zALL=%*


:: Strip off the first parm (sure hope lines aren't longer than 254 chars)

set zWORDS=%zALL:~2,255%


:: Make this line zee LastLine

set zLL=%zWORDS%


:: If this is the line we're looking for, make it zee LineOut

if {%1}=={%zIIDX%} set zLO=%zWORDS%


:: Keep track of line numbers

set /a zIIDX=%zIIDX% + 1

goto :eof




:awdun

echo ==%zLO%==


:: Be socially responsible

set zALL=

set zD1=

set zD2=

set zIDX=

set zIIDX=

set zLL=

set zLO=

:: But don't mess with seed

::set zNUM1=

set zNUM2=

set zWORDS=

输出一个空行:

echo.

脚本所在的路径(带驱动器):~dp0

set BAT_HOME=%~dp0
echo %BAT_HOME%
cd %BAT_HOME%

cmd.exe本身的/c参数，告诉它运行然后执行这些命令。

我曾经发现自己经常这样做:

win+r, cmd RETURN, ping google.com RETURN

但现在我只知道

win+r, cmd /c ping google.com返回

快得多。如果您正在使用pstools，并且希望使用psexec在远程机器上执行一些命令行功能，那么这也很有帮助。

EDIT: /k工作方式相同，但保持提示打开。这可能经常会派上用场。

为了从脚本内部解析stdin，你需要使用For和FIND命令:

for /f "tokens=*" %%g in ('find /V ""') do (
     :: do what you want with %%g
     echo %%g
)
