Can't empty trash in 10.3.9 Server

[PrepressAddict]

I have a folder in my trash on my OSX server that I can delete. It says its in use but it is not. I have restarted changed the name of the files with no luck.
I know there is a line of text i can use in the command line to force empty the trash. Does anyone know what the command is?

In terminal type sudo bash and then your password.

Next move the file out of the trash to your desktop and then cd to that directory and use the killall command.

cd /Users/YourUserName/Desktop

killall fileyouwanttodelete
