Hi there.
The first byte of the entry in the cataloge of the filesystem will be overwritten with a specific character. The space on the disk will only be released, if that file is not kept open by any processes anymore. Open files menas,
that some process is busy working on that file.
Get the utility lsof at http://hpux.asknet.de , which will help you to identify, which process keeps which file open.
To release the deleted file just kill the process, that keeps the file open.

If you have problems with HP-UX, pls place message in the appropriate forum.

Hi Anang,
As Alexander says, you kill the process id which is holding that file open. To find that process id command is "fuser -c filename"

In Unix some time even after killing processess it want go away. The only solution for that is to reboot the system. or
"kill 1 1" (This will restart the ineted)
