I had a workspace named him_wsc on my machine which was deleted long back. However I see that the client still exists in the depot.

While trying to delete it using the option

p4 client -d him_wsc

I am getting below error

Client 'him_wsc' has files opened. To delete the client, revert any opened files and delete any pending changes first. An administrator may specify -f to force the delete of another user's client.

Its not possible for me to get administrator access for perforce command, is there any hack or any other way to get it deletd from the depot?
