使用空格和转义字符完全控制输出:

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

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。

PAUSE

停止执行并显示如下提示:

Press any key to continue . . .

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。

您可以将if语句链接起来，以获得类似短路布尔' and'的效果。

if foo if bar baz

使用空格和转义字符完全控制输出:

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

这里将介绍如何通过扫描给定目录来构建CLASSPATH。

setlocal ENABLEDELAYEDEXPANSION
if defined CLASSPATH (set CLASSPATH=%CLASSPATH%;.) else (set CLASSPATH=.)
FOR /R .\lib %%G IN (*.jar) DO set CLASSPATH=!CLASSPATH!;%%G
Echo The Classpath definition is %CLASSPATH%

适用于XP(或更好)。对于W2K，您需要使用两个BAT文件来实现相同的结果(请参阅在类路径定义中包含所有jar)。

在1.6版本中不需要它，因为你可以直接在CLASSPATH中指定通配符(例如-cp ".\lib*")。
