Also, if you want to assign the drive letter to a variable directly, replace &quot;do echo %k&quot; with &quot;do set driveletter=%k&quot;<br />
<br />
then &quot;echo %driveletter% to see what happens.<br />
<br />

<div>
thx,<br />
<br />
so far I have this;<br />
&nbsp; &nbsp;echo list volume &gt;&nbsp;disklist.inf<br />
&nbsp; &nbsp;diskpart /s disklist.inf | find /i &quot;CATHERINE&quot; &gt;&nbsp;vollist.inf<br />
&nbsp; &nbsp;for /f &quot;&nbsp;tokens=3 &quot;&nbsp;%%I in (vollist.inf) do set USBDRIVE=%%I:<br />
<br />
You mentioned it's possible to get rid of the output files I create, I tried this;<br />
<br />
&nbsp; &nbsp;for /f &quot;tokens=3&quot; %%i in (echo list volume | diskpart /s | find /i &quot;BACKUP&quot;) do echo %%i:<br />
<br />
which seemed logical to me...until it failed :-)<br />
<br />

</div>


<div>
with pipe, and only drive name, for use in a batch file:<br />
<br />
for /F &quot;tokens=3&quot; %%D in ('echo list vol ^| diskpart ^| find &quot;BACKUP&quot;') do set drive=%%D<br />
<br />
Note the ^|, the carret is required to &quot;escape&quot; the pipe so the shell does not interpret it on first pass (but on second, when for argument is executed).<br />

</div>


<div>
I get an error;<br />
<br />
%%D was unexpected at this time.<br />
<br />

</div>


<div>
Use the &quot;usebackq&quot; option.<br />
<br />
for /f &quot;usebackq tokens=3&quot; %%i in (`echo list volume | diskpart /s | find /i &quot;BACKUP&quot;`) do echo %%i<br />
<br />
<br />
Here's a snippet from the help file...<br />
<br />

<pre><code class="code-10 nolinks" id="code-275168"><span>  Finally, you can use the FOR /F command to parse the output of a</span>
<span>  command.  You do this by making the file-set between the</span>
<span>  parenthesis a back quoted string.  It will be treated as a command</span>
<span>  line, which is passed to a child CMD.EXE and the output is captured</span>
<span>  into memory and parsed as if it was a file.  So the following</span>
<span>  example:</span>
<span> </span>
<span>    FOR /F &quot;usebackq delims==&quot; %i IN (`set`) DO @echo %i</span>
<span> </span>
<span>  would enumerate the environment variable names in the current</span>
<span>  environment.</span>
</code></pre>
</div>


<div>
No, usebackq is not of any use at the moment. It changes the way quotes are interpreted. The pipes have to be escaped anyway.<br />
<br />
My line with %%D was for use in batch file, as already posted. If you want to try it on commandline, use only %D:<br />
<br />
for /F &quot;tokens=3&quot; %D in ('echo list vol ^| diskpart ^| find &quot;CATHERINE&quot;') do set usbdrive=%D<br />

</div>


<div>
sorry,<br />
<br />
I knew that... just getting confused in my old age :-)<br />
<br />
all sorted thanks, upping the points...
</div>


<div>
Thanks chaps, great work!<br />
<br />
It was so the missus could do a backup without me and I needed to cater for almost all eventualities!<br />

Hi,<br />
<br />
I want to write a simple backup batch file to backup to a USB drive amongst other things.<br />
<br />
I can list the volume using diskpart /s diskscript.txt where diskscript.txt has &quot;list volume&quot; in it and then search for the diskname;<br />
eg/<br />
&nbsp; &nbsp;diskpart /s diskscript.txt | find &quot;BACKUP&quot;<br />
<br />
I now need to extract the disk volume from the string and assign it to a variable.<br />
&nbsp; Volume 4 &nbsp; &nbsp; F &nbsp; BACKUP &nbsp; &nbsp;FAT32 &nbsp;Removeable &nbsp;1934 MB<br />
<br />
I don't want to hard code the drive letter in the script as it may change. If awk was available as standard I'd be ok :-).<br />
<br />
Is there a MSDOS alternative? <br />
<br />
O/S is Windows XP Home/Professional.<br />
<br />
I will up the points for a quick response... hell I may even do it anyway! :-)<br />

Find drive letter of a named drive

Microsoft Disk Operating System (MS-DOS) was an operating system for x86-based personal computers, and traces of it are still found in the Windows operating system. DOS is still used in some embedded systems and for certain legacy 16-bit networks.

Microsoft DOS

Microsoft Windows XP is the sixth release of the NT series of operating systems, and was the first to be marketed in a variety of editions: XP Home and XP Professional, designed for business and power users. The advanced features in XP Professional are generally disabled in Home Edition, but are there and can be activated. There were two 64-bit editions, an embedded edition and a tablet edition.
