调用集——将环境变量展开几个层次。

在http://ss64.com/nt/call.html#advanced从另一个SO问题的答案中发现这个批处理文件变量在for循环中初始化

set VarName=Param
set Param=This

call set Answer=%%%Varname%%%
Echo %Answer%

给了

set VarName=Param
set Param=This
call set Answer=%Param%
Echo This
This

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。

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。

IF命令!没有它，我的批处理文件是垃圾!

@echo off
IF exist %windir%\system32\iexplore.exe goto end

echo Hmm... it seems you do not have Internet Explorer.
echo Great! You seem to understand ;)

:end
echo Hmm... You have Internet Explorer.
echo That is bad :)

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。
