如果你想通过在Windows资源管理器中双击一个批处理来运行它，并且想实际看到输出，而不仅仅是命令窗口的一闪而过，这很有用。

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

SHIFT

这是一种在命令行上迭代传递到脚本(或子例程)的可变数量的参数的方法。在最简单的用法中，它将%2转换为%1，将%3转换为%2，依此类推。(你也可以传递一个参数给SHIFT来跳过多个参数。)这使得命令具有“破坏性”(即%1永远消失)，但它允许您避免硬编码支持的参数的最大数量。

下面是一个简短的例子，一次处理一个命令行参数:

:ParseArgs

if "%1"=="" (
    goto :DoneParsingArgs
)

rem ... do something with %1 ...

shift

goto :ParseArgs


:DoneParsingArgs

rem ...

要获取当前日期/时间用于日志文件等，我在批处理文件中使用这个:

for /f "usebackq tokens=1,2,3,4,5,6,7 delims=/:. " %%a in (`echo %DATE% %TIME%`) do set NOW=%%d%%b%%c_%%e%%f%%g
set LOG=output_%NOW%.log

递归搜索目录树中的字符串:

findstr /S /C:"string literal" *.*

你也可以使用正则表达式:

findstr /S /R "^ERROR" *.log

递归文件搜索:

dir /S myfile.txt
