标题: 请教一个批处理的含义
本帖最后由有阴也有阳于 2016-9-19 21:35 编辑

请教下面一个批处理的含义：

@echo off
SHSUCDX /D:?PATACD01 /D:?SATACD01 /D:?SATACD02 /D:?SATACD03 /D:?USB-CD
findcd /s>nul
for %%i in (z,y,x,w,v,u,t,s,r,q,p,o,n,m,l,k,j,i,h,g,f,e,d,c) do if exist %%i:......

特别是其中的：

SHSUCDX /D:?PATACD01 /D:?SATACD01 /D:?SATACD02 /D:?SATACD03 /D:?USB-CD

是啥意思？

还有：

findcd /s>nul

是啥意思？

请高手赐教，谢谢！！！

等了半天，没有人回答，自己百度的资料：

@ECHO OFF //关闭回显

SHSUCDX /D:?PATACD01 // 这里的“？”是防止光驱设备名不当而出现错误信息；如果设备名不是IDE-CD, SHSUCDX就会忽略这一错误。

SHSUCDX /D:?PATACD01 /D:?SATACD01 /D:?SATACD02 /D:?SATACD03 /D:?USB-CD // 整行是寻找光驱设备从IDE——CD、SATA——CD

到USB——CD

问一句“：这里大写的字母‘D’是代表设备的意思吗？是单词设备的缩写吗？”

findcd /s>nul //找到光驱盘符

for %%i in (z,y,x,w,v,u,t,s,r,q,p,o,n,m,l,k,j,i,h,g,f,e,d,c) do //从C——Z中找到光驱盘符

等了半天没人回答，就去百度，以上内容百度来的，但还有一事不明：

像这么“低级”的问题，我也不知道，印象中好像在某个Dos盘里见过这个SHSUCDX，你看下它的帮助不就可以了，即使是英文的也可以翻译。。。

Command: shsucdx

  SHSUCDX is an unloadable CD-ROM redirector substitute for MSCDEX.
  It supports up to 10 drives. Each drive is single-sector buffered and
  the last 10 directory entries are cached. Each unit from each driver
  can be assigned a specific drive letter.
Syntax:

  shsucdx /D[:][?|*]driver[,[letter][,[unit][,[max]]]] [switches]
      DRIVER is the name of the device driver installed to control
      the CD-ROM drive. Prefixing the driver with '?' will
      silently ignore it if it does not exist (or is not actually a
      CD-ROM); prefixing with '*' will also ignore it, but a
      drive will be reserved (see below).
      LETTER is the first drive letter to assign to the units on
      this driver. The  default is the first available letter.
      Note: the drive letters assigned to subsequent units will
      always be higher than those assigned to previous units.
      UNIT is the first unit on this driver to be assigned a drive.
      Unit 0 is the default.
      MAX is the maximum number of units on this driver to be assigned
      drives. The default is all units (or all remaining units, if
      UNIT is given).
[Main menu] [top] (Syntax) [Options] [Comments] [Examples] [See also] [File]

Options:

  /D  Driver: This option is used to specify the name of the device
   driver. It can also indicate which unit(s) should be assigned and
   to what letter.
   Drive manipulation: At install time, /D can also be used to
   reserve space for additional drives. Use a single digit to indicate
   how many drives should be reserved (eg: /D1). (If you should happen
   to have a device driver name with a single digit, use the '?'
   prefix.) After installation, the same option will remove the
   drive(s) that were last assigned. It is possible to specify both
   forms of /D, in which case the current drive(s) will be removed,
   then the new drive(s) added. You can only use a drive letter which
   is smaller or even with the letter in LASTDRIVE / LASTDRIVEHIGH.
  /L  Letter: This option is an alternative to the LETTER component of
   /D, which it must follow (ie: /D:driver /L:letter). It can also be
   used to return the number of drives installed (/L:0, will return 255
   if not installed) and the letter of each assigned drive (/L:1, /L:2,
   etc., with A: = 1 and 255 if the drive is not assigned). You can only
   use a drive letter which is smaller or even with the letter in
   LASTDRIVE / LASTDRIVEHIGH.
  /C  Uses conventional instead of high memory.
  /V  Memory statistics: When this option is used at installation, a
   summary of memory usage will be displayed. This summary includes:
      Static Code and variables
      Dynamic  Data for each drive and paragraph rounding
      Total Overall memory usage
   Information: When used with /?, or after installation, this
   option displays the compile- and run-time options of SHSUCDX. This
   information includes:
      8086/386    The minimum processor required
      CD root form  TRUENAME will return \\D.\A.\ instead of D:\
      High Sierra The original format for the CD file system
      Joliet       The Windows format for long names
      Image on CD Enables access to an image which is itself on a CD
  /~ Tilde usage: The ISO standard allows for CDs to have names up to
      31 characters and Joliet can have names up to 64 characters. When
      this is reduced to 8.3 for DOS it may lead to duplicated entries.
      This option will remove the duplication by appending a tilded
      number after the name (similar to what Windows does). By default,
      tildes are off.
      This option is also available after installation. By itself it will
      toggle the status (ie. if tildes are currently on, /~ will turn
      them off and vice versa). Tildes can be explicitly turned on or
      off by adding a '+' or '-' sign (ie: /~+ will turn tildes on,
      irrespective of the current state). You do not have these problems
      when using the program DOSLFN.
  /R  Removes Read-only attribute.
  /I  Install anyway even if another redirector is present.
  /U  Unloads the shsucdx driver from memory.
  /Q  Quiet. Prevents display of the sign-on banner (copyright notice).

好象此批处理源于微软的 DOS 启动盘.

作者: alltask 时间: 2016-10-21 20:17
%~dpI    - 仅将 %I 扩展到一个驱动器号和路径
   %~nxI    - 仅将 %I 扩展到一个文件名和扩展名
   %~fsI    - 仅将 %I 扩展到一个带有短名的完整路径名
   %~dp$PATH:I - 搜索列在路径环境变量的目录，并将 %I 扩展
               到找到的第一个驱动器号和路径。
   %~ftzaI    - 将 %I 扩展到类似输出线路的 DIR
这些参数怎么个意思，能举个简单的例子吗？

echo off
echo %~dp0
pause

复制代码

把上面的批处理在不同目录运行下你就明白了
