XCOPY 仍在询问(F = file，D = 目录)确认

我的批处理脚本 xcopy仍然在请求 F = file, D = directory确认，尽管我已经在脚本中添加了 /F，日志如下所示。 请告诉我如何避免询问确认。

剧本:

net use p: /delete
net use p: "\\200clan\F_Drive" /USER:adm /PERSISTENT:NO-1111
set source=%1
set target=p:/%2


echo %source% %target%


xcopy /S /I /Q /Y /F "%source%" "%target%"

日志:

C:\test\foldera>xcopy /S /I /Q /Y /F "C:/test/folder1/folder2/logs/154/compareReport_177.html" "p:/Services/WSDLCompare/177_20151116/compareReport_177.html"
Does P:\Services\WSDLCompare\177_20151116\UIReport_177.html specify a file name
or directory name on the target
(F = file, D = directory)?

xcopy doesn't know the target is a directory. You clarify this by putting a backslash at the end:

xcopy /S /I /Q /Y /F "%source%" "%target%\"

The /I switch (not /F as you mentioned in your question) prevents xcopy from asking whether the destination is a file or a directory only if multiple source files are given, so if the source is a directory, or if wildcards ? or * are used. If the destination already exists, such prompt does never appear.

There are the following scenarios (depending on the provided values of %source% and %target%):

  • a single source file, the destination is a file:

    the /I switch is useless, so you need to pipe F into the xcopy command line:

    echo F|xcopy /S /Q /Y /F "%source%" "%target%"

    provided that the /Y switch is given (to force overwriting), you could also create the target file in advance (empty file):

    >> "%target%" rem/
xcopy /S /Q /Y /F "%source%" "%target%"

  • a single source file, the destination is a directory:

    the /I switch is useless too; you can pipe D into the xcopy command line:

    echo D|xcopy /S /Q /Y /F "%source%" "%target%"

    or you can simply append a \ to the destination:

    xcopy /S /Q /Y /F "%source%" "%target%\"

    although this causes trouble when %target% specifies the current directory of a drive like D: for instance, because D: means the current directory of this drive whereas D:\ means the root directory of it;

    or you create the destination directory in advance:

    2> nul mkdir "%target%"
xcopy /S /Q /Y /F "%source%" "%target%"

    the 2> nul portion suppresses the error message in case the directory already exists;

  • multiple source files, the destination is a file:

    this is usually a senseless situation, because you tell xcopy to copy each source file to the same destination file, thus attempting to overwrite it;

  • multiple source files, the destination is a directory:

    the /I switch makes sense here:

    xcopy /S /I /Q /Y /F "%source%" "%target%"

    the pipe option also works here:

    echo D|xcopy /S /Q /Y /F "%source%" "%target%"

    so does appending a \ to the destination (regarding the limitation as mentioned above):

    xcopy /S /Q /Y /F "%source%" "%target%\"

    or you create the destination directory in advance:

    2> nul mkdir "%target%"
xcopy /S /Q /Y /F "%source%" "%target%"

Conclusion

The most flexible and secure solution is to pipe the desired selection (F or D) into the xcopy command line. (Note that the query is locale-dependent.)

Supplement

There are some minor issues in your code fragment I want to mention here:

  • you should generally use the \ as a path separator as this is the Windows standard character for that purpose (although / works too in most cases);
  • there is -1111 appended to your second net use command line; if this constitutes the password for the resource, it should be moved before the /USER option; otherwise just remove it;
  • your set command lines introduce problems with some special characters (like &, ^, (, )); to avoid such, state set "source=%~1" and set "target=p:/%~2"; the ~ removes potential surrounding "" from the arguments (which are required if they contain SPACE, ,, ;, =);

Here is the code with the all of the above things reworked:

net use P: /DELETE
rem supposing `-1111` constitutes the password for the resource:
net use P: "\\200clan\F_Drive" -1111 /USER:adm /PERSISTENT:NO


set "source=%~1"
set "target=P:\%~2"


echo "%source%" "%target%"


rem supposing the destination is a directory:
echo D|xcopy /S /I /Q /Y /F "%source%" "%target%"




rem actually you do not need any interim variables:
REM echo D|xcopy /S /I /Q /Y /F "%~1" "P:\%~2"

Removing the destination filename will suppress the message. This works for me!

Put a \ behind the target to suppress the question and specify it as a folder:

xcopy src dest\

Put a * behind the target to suppress the question and specify it as a file:

xcopy src dest*

Note: The second command is a hack that relies on wildcard matching (will match any item starting with "dest") so use it at your own risk!

I use:

xcopy /S /I /Q /Y /F "%source%" "%target%"

It works.

Try:

echo F>xcopy_answer.tmp
xcopy xcopy /Q/Y "%source%" "%target%"<xcopy_answer.tmp

When copying a single file with XCOPY, there is no option to indicate if the destination is a filename or a directory (with the filename defaulting to that of the source file). In such cases XCOPY will prompt with a (locale specific) message like:

C:> xcopy foo.txt bar.txt

it prompts Does foo.txt specify a file name or directory name on the target (F = file, D = directory)?

Adding a wildcard (*) to the end of the destination will suppress this prompt and default to copying as a file:

C:> xcopy foo.txt bar.txt* 1 File(s) copied

This requires the source and target file extensions to be the same length, typically 3 characters.
