バッチスクリプト:ドライブ文字を繰り返し処理しますか?

Windowsバッチスクリプトで、物理ボリュームまたはマップされた共有に対応するすべてのドライブ文字を反復処理するにはどうすればよいですか?

また、言語の切り替えを提案しますが、VBSではなくPowershellに切り替えます。

Get-PSDrive -PSProvider FileSystem

それは未来の波です...

今はもっと良いツールがあるかもしれませんが、以前はfsutilコマンド(WinXP)がありました。

fsutil fsinfo drives

これにより、システム内のすべてのドライブが返されます。

これはうまくいくはずです。 forループからアクセスできる、接続されているすべてのドライブのアレイを作成します。あなたは今、ドライブであなたがやりたいことを何でもすることができます。私はそれがどのように機能するかを示すために2つの例を提供しました。

@echo off
setlocal enableDelayedExpansion
cls

REM getting the output from fsutil fsinfo drives and putting it in the ogdrives variable
FOR /F "tokens=* USEBACKQ" %%F IN (`fsutil fsinfo drives`) DO (
SET ogdrives=%%F
)
REM making the drives variable the same as the ogdrives variable so it can be manipulated
set drives=!ogdrives!

REM formating the out so that it looks like 1+1+1+... for every drive that is connected
set drives=!drives:Drives^: =!
set drives=!drives:^:\=1!
set drives=!drives: =+!

REM still formating to find out how many drives there are, this bit gets rid of any letters there are
set charms=0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ
for /L %%N in (10 1 62) do (
for /F %%C in ("!charms:~%%N,1!") do (
set drives=!drives:%%C=!
)
)
REM last for finding out the number, this removes the last characters since it is a leading + that shouldnt be there
set drives=!drives:~0,-1!
REM num is now the variable that contains the number of drives connected
set /a num=!drives!

REM reseting the drives variable to the original output so it can be manipulated again
set drives=!ogdrives!
REM this time it is being formated to list the drives as a solid string of drive letters like ABCD
set drives=!drives:Drives^: =!
set drives=!drives:^:\=!
set drives=!drives: =!

REM this is to iterate through that string of drive letters to seperate it into multiple single letter variables that are correlated to a number so they can be used later
:loop
REM the iter variable holds how many times this has looped so that when it hits the final drive it can exit
set /a iter=!iter!+1
REM the pos variable is the position in the string of drive letters that needs to be taken out for this iteration
set /a pos=!iter!-1

REM this sets the driveX variable where X is the drives correlated number to the letter of that drive from the long string of drive letters by using the pos variable
set drive!iter!=!drives:~%pos%,1!

REM this is checking to see if all drives have been assigned a number and if it has it will exit the loop
if !iter!==!num! goto oloop
goto loop
:oloop


REM drives are stored in variables %driveX% where X represents the drive number
REM the number of drives are stored in the %num% variable
REM below is an example for iterating through drives

REM this is an example of how to use the information gathered to iterate through the drives
REM we are using a for loop from 1 to the number of drives connected
for /L %%n in (1 1 !num!) do (
REM for every drive that is connected this will be ran
REM %%n contains a number which will increase since its a for loop
REM the drive driveX variable can then be used since drive1=A and drive2=B etc
echo drive %%n is !drive%%n!
REM you can see how i have embedded a variable inside a variable to create an array of sorts.
)
pause
exit
REM the actual variable names are drive1 drive2 drive3 but so that we can iterate through them we can just use a for loop and put the number in the variable
REM one way you can use this is with the where command since it will only search one drive at a time
REM you can do this like this 

for /L %%n in (1 1 !num!) do (

where /R !drive%%n!:\ *.txt

)

REM this will return a list of all txt files in the entire system since it searches all drives.

その場合、VBScriptを使用する方がはるかに簡単で、はるかに便利です。 http://authors.aspalliance.com/brettb/VBScriptDrivesCollection.asp

あなたは同軸にすることができます

wmic volume get driveletter

ここでデータソースになります。その後、標準のfor /fを使用して反復を実行できます。

あなたが試すことができます:

for %% i in(C D E F G H I J K L M N O P Q R S T U V W X Y Z)DO @if present %% i:@echo %% i:

このコードの主な制限は、ディスクのないCD/DVDドライブの存在です。これにより、ユーザーはコイにディスクを挿入します。すべてのCD/DVDドライブをZにマップしている場合:セットの最後のZを削除することで、コイを回避できます。
