使用空格和转义字符完全控制输出:

echo.    ^<resourceDir^>/%basedir%/resources^</resourceDir^>

整数运算:

> SET /A result=10/3 + 1
4

softwarejedi已经提到了for命令，但我将再次提到它，因为它非常强大。

下面以YYYYMMDD格式输出当前日期，我在生成备份目录时使用此格式。

for /f "tokens=2-4 delims=/- " %a in ('DATE/T') do echo %c%b%a

搜索路径上的可执行文件(或其他类似路径的字符串，如果需要):

c:\> for %i in (cmd.exe) do @echo. %~$PATH:i
C:\WINDOWS\system32\cmd.exe

c:\> for %i in (python.exe) do @echo. %~$PATH:i
C:\Python25\python.exe

c:\>

我真的很喜欢这个Windows XP命令参考，以及在顶部的语法链接;它涵盖了许多已经在其他答案中找到的技巧和技巧。

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=
