Question

在完成这个项目的编码之前，我正处于我的最后一个挑战。我试图过滤diskpart的列表分区和列表卷命令的输出，而不使用临时文件。

我有解决方案：

set /A hdd= 0
rem Use this for the partition listing:
set cmd="echo select disk %hdd%^&list partition| diskpart"

rem and this for the volume listing (doesn't need the select disk):
set cmd="echo select disk %hdd%^&echo list volume | diskpart"

for /F "skip=7 usebackq delims=" %%? in (`!cmd!`) do (
   set line=%%?
   set cut=!line:~0,8!
   if NOT !cut!==DISKPART echo %%?
)

echo.
pause

可能有一种方法可以将for循环中的2个设置行合并为一个，甚至可以将循环内的所有3行减少为一行，但我的所有尝试都失败了。

以下是输出结果的示例：

Partition ###  Type              Size     Offset
-------------  ----------------  -------  -------
Partition 1    Primary           1000 MB  1024 KB
Partition 2    Primary             78 GB  1001 MB
Partition 0    Extended            29 GB    79 GB

或者是卷列表：

Volume ###  Ltr  Label        Fs     Type        Size     Status     Info
----------  ---  -----------  -----  ----------  -------  ---------  ------
Volume 0     B                       DVD-ROM         0 B  No Media
Volume 1     D                       DVD-ROM         0 B  No Media
Volume 2     C   Windows 7 U  NTFS   Partition     78 GB  Healthy    System

在概念上看起来似乎很简单，但对于批量的众多语法怪癖来说，这很简单！

这个问题归结为如何减少for循环中的行。

感谢您提出的任何建议。

下一个脚本显示了另一种方法;以等号（for /F）显示%%?循环变量=%%?=，以显示diskpart输出相当含量。前导和尾随空格：

@ECHO OFF
SETLOCAL EnableExtensions DisableDelayedExpansion
set "cmd=echo list disk | diskpart"
call :listCmd
call :listPar "echo list disk | diskpart" 
call :listPar "echo list volume | diskpart" 
call :listPar "(echo select disk 1 & echo list partition) | diskpart" 
ENDLOCAL
goto :eof

:listCmd
echo %~0 %*
for /F "skip=7 usebackq delims=" %%? in (`"%cmd%"`) do (
  if "%%?" NEQ "DISKPART> " echo(=%%?=
)
goto :eof

:listPar
echo %~0 %*
for /F "skip=7 usebackq delims=" %%? in (`"%~1"`) do (
  if "%%?" NEQ "DISKPART> " echo(=%%?=
)
goto :eof
