子字符串变量:

> set str=0123456789
> echo %str:~0,5%
01234
> echo %str:~-5,5%
56789
> echo %str:~3,-3%
3456

我总是发现很难阅读每行用关键字标记的注释:

REM blah blah blah

易于阅读:

:: blah blah blah

There is also the EDLIN command. While it may be an old bastard tool once used for line-based text editing, the fact that it's controllable from the command line makes it rather useful for batch scripting, mostly because, just like any other case you'd be using EDLIN, it's the only tool available. After all, EDLIN is not a tool you would ordinarily want to use for text editing, unless you are somewhat masochistic. To quote Tim Patterson (the fellow who wrote it): "I was aghast when I heard that IBM was using it and not throwing it out the window."

注意:EDLIN将老式的EOF (1A)标记添加到它编辑的文件中。如果需要删除它们，可能必须使用DEBUG。

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:\>

狡猾的等待N秒的技巧(不是cmd.exe的一部分，但不是额外的软件，因为它是Windows自带的)，参见ping行。您需要N+1个ping，因为第一个ping没有延迟。

    echo %time%
    call :waitfor 5
    echo %time%
    goto :eof
:waitfor
    setlocal
    set /a "t = %1 + 1"
    >nul ping 127.0.0.1 -n %t%
    endlocal
    goto :eof

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 ...
