Rapid as in lighting quick. If a file comes in at 5:59:59 pm, the warehouse wants me to turn the file into a sales order and get it to them for picking by 6:00:00 pm. That's a bit of an exaggeration but not much.
Also, I forgot to mention that the application that is putting files in the directory is external and I have no way of changing it. I figured out that I can move the fuser command outside of the loop and use the * wildcard character. This way I can build an array of files that are in use and locate the file from the ls command in the array and if there consider it inuse. Much much faster than executing through each iteration of the loop. Gotta love the wildcard characters. Thanks to all who took time out of their day to help me.
