If actual elapse time is critical because of ongoing processing, could I suggest:-

Code:

mv /path /path-to-del
mkdir -m 777 /path
chown user:group /path

Doing this will be a near instantaneous operation and then with the directory renamed and a new empty one created, your processing can continue whilst you dispose of what is now called /path-to-del at your leisure.

The -m 777 on the mkdir sets the permissions for the directory. The user:group on the chown sets both the owner and group in one operation, rather than having to do a chown and a chgrp

I might be way off course, but I was confused as to why the timing matters so much. If you still want a choice for your original question, I would go with rm -f /path

Another alternate might be available if this is a filesystem you can unmount for a few moments:-

Code:

umount /path
newfs your-options /dev/logical-volume
mount /path

You don't give us an OS or any clue about what devices the disks are on, so I've tried to be generic here. You make have to use mkfs, crfs, fscreate or other things depending what you are running. Of course, this may not be an option.

I hope that these suggestions might help.
