我想[y/n]
通过批处理来做一个非常简单的问题。
我可以让它等待不到一秒钟就自动选择默认选项吗?比如
choice /d Y /t .5
答案1
从Choice.exe /?
:
/T timeout The number of seconds to pause before a default
choice is made. Acceptable values are from 0 to
9999. If 0 is specified, there will be no pause
and the default choice is selected.
由于他们说的是完整的“秒”,所以您必须选择一个从 0 到 9999 的整数;您不能使用秒的分数(在这些情况下他们通常会要求使用毫秒)。
但是你能使用 0 来请求不延迟,这应该会使其尽可能快。
choice /T 0 /D Y
注意:这是在 Windows 7 上检查的,您的 Choice.exe 版本可能会有所不同。;)
choice.exe 的完整帮助
C:\choice /?
CHOICE [/C choices] [/N] [/CS] [/T timeout /D choice] [/M text]
Description:
This tool allows users to select one item from a list
of choices and returns the index of the selected choice.
Parameter List:
/C choices Specifies the list of choices to be created.
Default list is "YN".
/N Hides the list of choices in the prompt.
The message before the prompt is displayed
and the choices are still enabled.
/CS Enables case-sensitive choices to be selecte
By default, the utility is case-insensitive.
/T timeout The number of seconds to pause before a defa
choice is made. Acceptable values are from 0
9999. If 0 is specified, there will be no pa
and the default choice is selected.
/D choice Specifies the default choice after nnnn seco
Character must be in the set of choices spec
by /C option and must also specify nnnn with
/M text Specifies the message to be displayed before
the prompt. If not specified, the utility
displays only a prompt.
/? Displays this help message.
NOTE:
The ERRORLEVEL environment variable is set to the index of the
key that was selected from the set of choices. The first choice
listed returns a value of 1, the second a value of 2, and so on.
If the user presses a key that is not a valid choice, the tool
sounds a warning beep. If tool detects an error condition,
it returns an ERRORLEVEL value of 255. If the user presses
CTRL+BREAK or CTRL+C, the tool returns an ERRORLEVEL value
of 0. When you use ERRORLEVEL parameters in a batch program, lis
them in decreasing order.
Examples:
CHOICE /?
CHOICE /C YNC /M "Press Y for Yes, N for No or C for Cancel."
CHOICE /T 10 /C ync /CS /D y
CHOICE /C ab /M "Select a for option 1 and b for option 2."
CHOICE /C ab /N /M "Select a for option 1 and b for option 2."
