There's no such thing, that I know of, as 'kill hanging files'. 'lsof'
will give you process id's (PID values) with lots of other info, unless
-t is used, which is just the list of PID values.
You then use the PID values to kill the processes.
Indeed I wrote about "pipe" to a kill command.
When a process dies, all its open files are closed, either by itself or
by the system on its behalf. This is true even if 'kill -9' is used,
the system takes cleanup on exit very seriously.
Clear, but what happens when an application crashes? Did the system/process acts as said before?
The net result is that open files go away, and the filesystem is no
longer 'busy' and can be umount'ed.
Shall we start a new thread? :)
