Files don't get deleted unless someone or a script did it.
I assume this isn't /tmp or /var/tmp?

Tell exactly (giving actual commands) of what happened. Then, we may be able to help you out.

There is no magical deletion reported on HP UX till now! :)

So, either someone/script deleted it behind your back. Or you mounted another file system on that directory, which makes the existing files before mount 'invisible', not 'deleted'.

Hi,

Please check your crontab job with
#crontab -l

or may any scheduler job is running.

some script will be there behind this check every job which is running in cron.

Hi Shin ,

As the previous writers said .

Automatic deletion can happen only , by script/ scheduler.

If the system is trusted/ auditing is enabled.

From the logs you can find out the deletion , where/ how/ who has done it.

Thanks,
Analyst.

Apart from scripts and jobs
there are the Classic unix user 'misunderstandings'

I just name 3, but there are many others

1) trying to delete a .profile with rm .*
which will delete a lot more

2) Trying to cat or sed and output to same name cat file > file or sed < file > file

3) mv file /farawayddir/foobaar

etc etc

Just restore the file from your backup,
also ensure that your owner and privileges
are what you expect. (don't user chmod 777 for instance )
