在bat脚本中使用空格,不带引号

Question

我需要跑

start cmd.exe /k "C:\Program Files (x86)\Mozilla Firefox\sdk\bin\activate & cd d:\home\name\addon\ & cfx run"

问题是第一个路径有空格(Program Files).我不能使用引号,因为它们已用于完整命令.

如何在此命令中使用空格？

Answer 1

谁说在引用/ C命令时你不能在exe路径周围添加引号？它工作正常!:-)

start cmd.exe /k ""C:\Program Files (x86)\Mozilla Firefox\sdk\bin\activate" & cd d:\home\name\addon\ & cfx run"

/ C命令周围的外引号在执行之前被删除,只留下exe路径周围的引号.您可以在帮助中阅读有关CMD流程报价的方式.只需键入CMD /?或HELP CMD从命令提示符.它确实令人困惑.

If /C or /K is specified, then the remainder of the command line after
the switch is processed as a command line, where the following logic is
used to process quote (") characters:

    1.  If all of the following conditions are met, then quote characters
        on the command line are preserved:

        - no /S switch
        - exactly two quote characters
        - no special characters between the two quote characters,
          where special is one of: &<>()@^|
        - there are one or more whitespace characters between the
          two quote characters
        - the string between the two quote characters is the name
          of an executable file.

    2.  Otherwise, old behavior is to see if the first character is
        a quote character and if so, strip the leading character and
        remove the last quote character on the command line, preserving
        any text after the last quote character.

您的命令有两个以上的引号,因此遵循选项2.

如果你的exe名称包含一个特殊的字符&,例如,上面这段时间不起作用的唯一时间this&that.exe.这会导致问题,因为最初解析START命令时不会引用exe名称.可以通过转义文件名中的问题字符来解决这个问题.

start cmd.exe /k ""this^&that.exe" & echo something else"
