RE: Who clears /tmp regularly

Yes, I'm aware a file in use can still be accessed.

We're going to have to disagree on the second point. I would not expect an admin to be familiar with the (subtle?) nuances of the myriad of applications likely running on the system.

Hello Roger,

Wow. I'd be leery of wiping out a file that was needed by some active job.

On UNIX, you can easily remove a link to a file despite it being used. Space on disk isn't freed until all file handles referencing the file are closed. I assume PASE emulating AIX works in a similar way.

If you use such a file to pass data between individual applications, this will not work, indeed. But then, the sysadmin should know what's going on on his machine? ;-)

:wq! PoC
