set 命令详解.doc

set 命令详解 显示、设置或删除 cmd.exe 环境变量。SET variable=stringvariable 指定环境变量名。string 指定要指派给变量的一系列字符串。要显示当前环境变量，键入不带参数的 SET。如果命令扩展被启用，SET 会如下改变:可仅用一个变量激活 SET 命令，等号或值不显示所有前缀匹配SET 命令已使用的名称的所有变量的值。例： SET P会显示所有以字母 P 打头的变量如果在当前环境中找不到该变量名称，SET 命令将把 ERRORLEVEL设置成 1。SET 命令不允许变量名含有等号。在 SET 命令中添加了两个新命令行开关:SET /A expressionSET /P variable=promptString/A 命令行开关指定等号右边的字符串为被评估的数字表达式。除十六进制有 0x 前缀，八进制有 0 前缀的，数字值为十进位数字。因此，0x12 与 18 和 022 相同。请注意八进制公式可能很容易搞混: 08 和 09 是无效的数字，因为 8 和 9 不是有效的八进制位数。/P 命令行开关允许将变量数值设成用户输入的一行输入。读取输入行之前，显示指定的 promptSmptString 可以是空的。%PATH:10,5%会扩展 PATH 环境变量，然后只使用在扩展结果中从第 11 个(偏移量 10)字符开始的五个字符。如果没有指定长度，则采用默认值，即变量数值的余数。如果两个数字(偏移量和长度)都是负数，使用的数字则是环境变量数值长度加上指定的偏移量或长度。%PATH:-10%会提取 PATH 变量的最后十个字符。%PATH:0,-2%会提取 PATH 变量的所有字符，除了最后两个。如果命令扩展被启用，有几个动态环境变量可以被扩展，但不会出现在 SET 显示的变量列表中。每次变量数值被扩展时，这些变量数值都会被动态计算。如果用户用这些名称中任何一个定义变量，那个定义会替代下面描述的动态定义:%CD% - 扩展到当前目录字符串。%DATE% - 用跟 DATE 命令同样的格式扩展到当前日期。%TIME% - 用跟 TIME 命令同样的格式扩展到当前时间。%RANDOM% - 扩展到 0 和 32767 之间的任意十进制数字。%ERRORLEVEL% - 扩展到当前 ERRORLEVEL 数值。%CMDEXTVERSION% - 扩展到当前命令处理器扩展版本号。%CMDCMDLINE% - 扩展到调用命令处理器的原始命令行。应用例子：echo off title Windows Xp 优化文件!
