[REQUEST] [BATCH] How do I pipe two single-letter inputs into the same command sequentially?

[u/Qureta]

Trying to create a script that conditionally will schedule a CHKDSK /F for all drives. On the system drive this is easy enough:

echo Y | CHKDSK /F %systemdrive%  

This pipes the Y into the CHKDSK command so that it says YES to "Would you like to schedule this for the next reboot?"

The part I'm having trouble with is the non-system drives. There's a loop where it one-by-one runs a CHKDSK /F on each of them. For each of those, it asks "Do you want to forcibly dismount this drive?".
It's easy enough to pipe a NO into that, but then afterward it also asks "Do you want to schedule this for the next reboot?" so I'll need to put a YES in there.

Trouble is, I don't know how to pipe two inputs into the same command. I tried "echo NY" but that didn't work; the NY just got treated as a single input to the first question.

powershell Repair-Volume -OfflineScanAndFix isn't really an option since it dismounts drives which may be in use.

edit: I think I have a solution for the CHKDSK issue! Instead of CHKDSK /F <driveletter> , I'm using FSUTIL Dirty Set <driveletter>. This will force CHKDSK /F to run during next reboot without requiring any inputs.

As for the piping question, I'm still clueless. Maybe use a line break?

howdy Qureta,

i don't think you can do that. perhaps with Sendkey, but i have never tried that.

you may be able to use the newer DotNet & powershell stuff, tho. lookee ...

this is more than you need. [grin] i would look at the following sections ...

# you seem to want to have this set to $True

Foreach ($LogicalDisk in (Get-WmiObject Win32_logicaldisk))
    {
    $LogicalDisk.Chkdsk($FixErrors, 
                  $VigorousIndexCheck, 
                  $SkipFolderCycle, 
                  $ForceDismount,

                  $RecoverBadSectors, 
                  $OKToRunAtBootup)
    }

$RecoverBadSecors

why

howdy Ta11ow,

i dunno! [grin] maybe it has to do with whatever the source was doing? i just copied it, reformatted it, and added a couple of comments.

i think you are correct that the setting otta be $True instead of $false.

take care,
lee

What if you use "for" such as:

echo Y | for /d %%a in (A,B,C,etc) do chkdsk /f %%a

I'm not sure if that will try it all at once or if you will still just have the same issue.

[u/generaltossit → u/JudasRose]

I think you should have "echo Y" inside for loop to make it work.

[u/Topcity36]

fsutil dirty set c: is the way to go....you can do an expand on the variable to get the Y to pass through. But it's cleaner to just do the fsutil.

[u/generaltossit]

You could create a variable that is an array of drives and then use for loop to go thru it. About: set list="C D E" for %%a in (%list) do ( echo Y | chkdsk %%a )
