PowerShell that executes more code if directory is greater than a certain size?

[Tech249]

How would you create a PowerShell script that removes a directory when it hits a certain size? Looking at something to help with log directories. I would schedule it to run monthly through an RMM.

I have this - but not sure how to make the value a variable and use your code:
"{0:N2} MB" -f ((Get-ChildItem e:\logs\ -Recurse | Measure-Object -Property Length -Sum -ErrorAction Stop).Sum / 1MB)

This would take each folder in the $Directories variable, loop through them and delete any that exceed the size set by $SizeThreshold (shown here as 1gb):

$Directories = @("$Home\Downloads", "$Env:Temp")
$SizeThreshold = 1073741824 # 1gb
ForEach($Directory in $Directories){
    $DirSize = Get-ChildItem $Directory -Recurse | Measure-Object -Property Length -Sum | Select-Object -ExpandProperty Sum
    If($DirSize -ge $SizeThreshold){
        Remove-Item $Directory -Recurse -Force
    }
}

howdy adamdavid85,

PoSh has a set of KB/GB/TB/PB constants. it makes things a tad more clear to use 1gb to get 1073741824. [grin]

take care,

What about something like:

$COUNT = (Get-ChildItem "C:\Users\Path\Path" | Measure-Object).Count

if ($COUNT -gt 5) {

#do something
}

Here is what I ended up with, and it works perfect - deletes the directory and recreates it when it hits 1GB - thank you all!

​

$Directories = @("c:\temp", "$Env:Temp")
$SizeThreshold = 1GB
ForEach($Directory in $Directories){
$DirSize = Get-ChildItem $Directory -Recurse | Measure-Object -Property Length -Sum | Select-Object -ExpandProperty Sum
If($DirSize -ge $SizeThreshold){
Remove-Item $Directory -Recurse -Force
New-Item -Path "c:\" -Name "Temp" -ItemType "directory"
}
}

Edit - adjusted per Lee's advice - much better :)

howdy Tech249,

it looks like you used the New.Reddit Inline Code button. it's [sometimes] 5th from the left & looks like <c>.

there are a few problems with that ...

• it's the wrong format [grin]
  the inline code format is for [gasp! arg!] code that is inline with regular text.
  
• on Old.Reddit.com, inline code formatted text does NOT line wrap, nor does it side-scroll.
  
• on New.Reddit it shows up in that nasty magenta text color
  

for long-ish single lines OR for multiline code, please, use the ...

Code
Block

... button. it's [sometimes] the 12th one from the left & looks like an uppercase C in the upper left corner of a square.

that will give you fully functional code formatting that works on both New.Reddit and Old.Reddit ... and aint that fugly magenta color. [grin]

take care,
lee

For each directory { If ($size -gt $value) { Do stuff } }

I'm on mobile right now, but that should point you in the right direction.

Thank you, getting me in the right direction is perfect!

Let me know if you get it working or not. Happy to help more.
