[英]Stop Powershell Script if disk size is less than X
I wonder if you could help me out guys.我想知道你们是否可以帮助我。 I need to stop a powershell script if the disk size of partition E is less than 10GB, and to continue if it´s more than 10GB.如果分区 E 的磁盘大小小于 10GB,我需要停止 powershell 脚本,如果大于 10GB,则继续。
So far i managed to get my disk size listed with this.到目前为止,我设法列出了我的磁盘大小。
Get-WmiObject -Class win32_logicaldisk | Format-Table DeviceId,@{n="FreeSpace";e={[math]::Round($_.FreeSpace/1GB,2)}}
And i get this result:我得到这个结果:
DeviceId设备编号 | Freespace可用空间 |
---|---|
A一种 | 0 0 |
C C | 77.9 77.9 |
D丁 | 0 0 |
E乙 | 34.05 34.05 |
So, i want to stop the powershell script if E unit has less than 10GB.所以,如果 E 单元小于 10GB,我想停止 powershell 脚本。 How can i do it?我该怎么做?
Thanks in advance提前致谢
If you want to put the Freespace of E in a variable you can do this:如果你想把 E 的自由空间放在一个变量中,你可以这样做:
$VarSpace = $(Get-WmiObject -Class win32_logicaldisk | Where-Object -Property Name -eq C:).FreeSpace/1GB
then you can do a simple if for check:那么你可以做一个简单的 if 来检查:
if ($VarSpace -le 10){ <Something for stopping you script like exit> }
You can use the Get-Volume cmdlet for that or Get-CimInstance
rather than the old Get-WmiObject
:您可以为此使用Get-Volume cmdlet 或Get-CimInstance
而不是旧的Get-WmiObject
:
$freeOnE = (Get-CimInstance -ClassName win32_logicaldisk | Where-Object {$_.DeviceID -eq 'E:'}).FreeSpace / 1GB
or或者
$freeOnE = (Get-Volume -DriveLetter E).SizeRemaining / 1GB
Then exit your PowerShell session if this value is below 10Gb如果此值低于 10Gb,则退出 PowerShell session
if ($freeOnE -lt 10) { exit }
