Check If Azure Resource Group Exist - Azure Powershell

问题

I'm trying to verify if ResourceGroup exist or not so i thought that following code should return true or false, but it doesn't output anything.

$RSGtest = Find-AzureRmResource | Format-List ResourceGroupName | get-unique
$RSGtest -Match "$myResourceGroupName"

Why am I not getting any output?

回答1:

There is a Get-AzureRmResourceGroup cmdlet:

Get-AzureRmResourceGroup -Name $myResourceGroupName -ErrorVariable notPresent -ErrorAction SilentlyContinue

if ($notPresent)
{
    # ResourceGroup doesn't exist
}
else
{
    # ResourceGroup exist
}

---

Note: Consider using the new Get-AzResourceGroup cmdlet:

Get-AzResourceGroup -Name $myResourceGroupName -ErrorVariable notPresent -ErrorAction SilentlyContinue

if ($notPresent)
{
    # ResourceGroup doesn't exist
}
else
{
    # ResourceGroup exist
}

try this

$ResourceGroupName = Read-Host "Resource group name"
Find-AzureRmResourceGroup | where {$_.name -EQ $ResourceGroupName}
