推荐答案
批处理文件似乎无法实现.一种明显的解决方法是编写或查找可以从批处理文件运行的控制台应用程序，但是……这样做值得吗?我不这么认为吗?如果批处理文件可以在任何系统中工作，而无需其他实用程序，尤其是仅为扩展批处理功能而编写的实用程序，则它们具有很大的价值.
顺便说一句，您可以轻松了解批处理文件可以执行的所有操作.为此，您可以在与系统上的批处理文件功能有关的所有主题上自动构建帮助文件.要获取它，您需要运行此批处理:
It does not seem possible with batch files. The apparent workaround it to write or find a console application which you could run from your batch file, but… does it pay of to bother about it? I don''t think so? The batch files have considerable value if they can work in any system, without additional utilities, especially those written only for the purpose of extending batch functionality.
By the way, you can easily learn everything batch files can do. For this purpose, you can automatically build a help file on all topics related to batch file functionality on your system. To get it, you need to run this batch:
@ECHO OFF
IF "%OS%"=="Windows_NT" SETLOCAL DISABLEDELAYEDEXPANSION
:: Version number for this batch file
SET MyVer=1.40
:: Display "about"
ECHO.
ECHO AllHelp.bat, Version %MyVer% for Windows NT 4 / 2000 / XP
ECHO Generate an HTML help file for "all" available commands
ECHO.
ECHO Note:
ECHO This batch file uses the redirected output of the HELP command to generate the
ECHO HTML file. Because some commands use "special" characters like ^&, ^<, and ^> in
ECHO their help screen, not all output is displayed correctly in the browser.
ECHO Known issues: skipped ^<space^> "tag" in CMD's special character list and skipped
ECHO \^<xyz and xyz\^> word position references in FINDSTR's output.
ECHO.
