XCOPY 仍在询问(F = 文件，D = 目录)确认 [英] XCOPY still asking (F = file, D = directory) confirmation

问题描述

我的批处理脚本 xcopy 仍然要求 F = file, D = directory 确认，即使我在脚本中添加了 /F，日志显示如下.请帮助说明如何避免要求确认.

脚本:

net use p:/deletenet use p: "\200clanF_Drive"/USER:adm/PERSISTENT:NO-1111设置源=%1设置目标=p:/%2回声%源%%目标%xcopy/S/I/Q/Y/F "%source%" "%target%"

解决方案

/I 开关(不是您在问题中提到的 /F)阻止 xcopy 仅当给出多个源文件时才询问目标是文件还是目录，所以如果源是目录，或者如果通配符?或*被使用.如果目的地已经存在，则不会出现此类提示.

有以下场景(取决于%source%和%target%的提供值):

• 单个源文件，目标是一个文件:

  /I 开关没用，所以你需要将 F 通过管道传送到 xcopy 命令行:

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

  如果给定了/Y开关(强制覆盖)，你也可以提前创建目标文件(空文件):

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

• 单个源文件，目标是一个目录:

  /I 开关也没有用；您可以通过管道将 D 导入 xcopy 命令行:

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

  或者您可以简单地将 附加到目的地:

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

  虽然这会在 %target% 指定驱动器的当前目录时造成麻烦，例如 D:，因为 D: 意味着此驱动器的当前目录，而D: 表示它的根目录；

  或者你提前创建目标目录:

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

  <代码>2>如果目录已存在，则 nul 部分会抑制错误消息；

• 多个源文件，目标是一个文件:

  这通常是一种毫无意义的情况，因为你告诉 xcopy 将每个源文件复制到同一个目标文件，从而试图覆盖它；

• 多个源文件，目标是一个目录:

  /I 开关在这里很有意义:

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

  管道选项在这里也有效:

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

  将 附加到目的地也是如此(关于上述限制):

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

  或者你提前创建目标目录:

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

结论

最灵活和最安全的解决方案是将所需的选择(F 或 D)通过管道传输到 xcopy 命令行.(请注意，查询依赖于语言环境.)

补充

您的代码片段中有一些小问题，我想在这里提一下:

• 您通常应该使用 作为路径分隔符，因为这是用于此目的的 Windows 标准字符(尽管 / 在大多数情况下也适用)；
• 有 -1111 附加到您的第二个 net use 命令行；如果这构成了资源的密码，则应将其移到 /USER 选项之前；否则就删除它；
• 您的 set 命令行引入了一些特殊字符问题(例如 &、^、(、<代码>));为了避免这种情况，声明 set "source=%~1" 和 set "target=p:/%~2";~ 从参数中删除潜在的包围 ""(如果它们包含 SPACE、、、<代码>;, =);

以下是重做上述所有内容的代码:

net use P:/DELETErem 假设 `-1111` 构成资源的密码:net use P: "\200clanF_Drive" -1111/USER:adm/PERSISTENT:NO设置源=%~1"设置目标=P:\%~2"echo "%source%" "%target%"rem 假设目的地是一个目录:echo D|xcopy/S/I/Q/Y/F "%source%" "%target%"rem 实际上你不需要任何临时变量:REM echo D|xcopy/S/I/Q/Y/F "%~1" "P:\%~2"

My batch script xcopy is still asking F = file, D = directory confirmation even though I have added /F in the script, the log is showing as below. Please help on how to avoid asking confirmation.

Script:

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

echo %source% %target%

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

Log:

C:	estfoldera>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:ServicesWSDLCompare177_20151116UIReport_177.html specify a file name
or directory name on the target
(F = file, D = directory)? 

解决方案

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: "\200clanF_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"
