Powershell - Delete / remove all site collection under a spesific managed path

Question

I've created a managed path for my team sites - called "workspaces". All team sites Have been created under the same managed path.

 ex: 
 http://awesome.com/workspaces/teamsite1
 http://awesome.com/workspaces/teamsite2

How can I list all team sites under a managed path?

What I want is to delete all site collection under a specific managed path. (remove site collection and DB-entry)

Answer 1

To list them, this actually gives you all sites under the path though:

Get-SPSite "http://awesome.com/workspaces*" -Limit ALL

To delete you should be able to use

Get-SPSite "http://awesome.com/workspaces*" -Limit ALL | Remove-SPSite -Confirm:$false

You can use

Remove-SPContentDatabase -Identity {GUID}

to remove a content database

Answer 2

You can delete site collection using powershell by using following command

$tmpRoot = Get-SPWebApplication -Identity http://SP:2000
$tmpRootColl=$tmpRoot.Sites
#Enumerate through each site collection
for ($index=$tmpRootColl.Count-1 ; $index-ge 0 ; $index–-)
{
  Remove-SPSite -Identity $tmpRootColl.Item($index) -GradualDelete -Confirm:$false
}
Get-SPDeletedSite | Remove-SPDeletedSite

Where $tmpRoot is Web Application and $tmpRootColl is collection of sites under web application
