Now, i'm not sure its the best way to do this, but it works. I wanted to ensure we weren't trying to delete busy snaps so I through in $_.busy -like "*false*". I tried -eq "false" but it wouldn't return anything which was confusing to me .
Now remember i'm very new to powershell so any criticism is welcome. I didn't know a good way to log in one line and then delete in another so, I had to run the cmdlet again. Any suggestions for imporvement are welcome.
