Hello,

I am wanting to remove some files from a directory based on some criteria
and the script works, however, I don't want the confirmation to prompt, I
just want the files to delete, however, when I include the -confirmation
parameter, PowerShell throws an error saying it can't match it. Here is what
I currently have that is not working:

Remove-Item -path .\. -confirm A | Get-ChildItem | Where { $_.Length -Le
1000000 }

"A" is suppose to be the "Yes to All" and that is what I want to pass. What
is the correct syntax for this?



Thanks,
Flea#

The default behavior is to NOT prompt.

Remove the -Confirm

And your logic looks backwards

Get-ChildItem | Where { $_.Length -Le 1000000} | remove-item -force -whatif


REMOVE the whatif if this does what you expect.

Thanks Brandon, I switched it around as you said and that seemed to fix the
issue. I did it this way and it worked as you said.

Get-ChildItem -Filter *.log | Where { $_.Length -Le 1000000 } | Remove-Item

To complement Brandon's answer:

-Confirm is a [Switch] parameter. These parameters can either be present ($true) or not ($false), i.e., no argument can be pass to them. You can set it to either state like this:

$confirm = $true
Get-ChildItem | Where {$_.Length -Le 1000000} | Remove-Item -confirm:$confirm
# is equivalent to:
Get-ChildItem | Where {$_.Length -Le 1000000} | Remove-Item -confirm

$confirm = $false
Get-ChildItem | Where {$_.Length -Le 1000000} | Remove-Item -confirm:$confirm
# is equivalent to:
Get-ChildItem | Where {$_.Length -Le 1000000} | Remove-Item

In the case above, you can pass $false as a parameter in cases where you
want to be positive you won't be prompted, for example in a production
script. Another way to do the same thing is this:

Remove-Item -Confirm:$false
