how to make the contents of a file disappear after x numbers of days or at date
Anybody know of a way to make the contents of a file (txt, html, jpeg,
png, mp3, ogg etc.) disappear after a certain number of days.
To make the whole content or a selected part of a file to disappear.
The charateristic must be hidden in the file and not to be removed by a
copy.
I should be a kind of wipe operation :-)

Can you explain what you mean with "disappear"? Should the result be an
empty file or e.g. a file with the same length and random data?

I mean the result should be an empty file (or a part of a file), where
the "wiped" data is gone and cannot be restored.

Do you want an empty file or a deletion of the file?
If the latter, use cron.

Probably you can do what you want with the package wipe and a script in
/etc/cron.daily/ (or /etc/cron.hourly/) which would delete (wipe) old
files in a given directory tree. But your description is still too vague
to give more detailed advice.

Cron. https://help.ubuntu.com/community/CronHowto
write a script to remove files. It can even have a config for a list
of files to remove at those intervals.
Also, you can check the date of the files and current time if you want
time elapsing. I personally want to switch to using the discordian
date system.

I don't think using that date system would make any difference as the
OP just wants elapsed days.

Pdf was not included in my mind in my question as I find pdf clumsy to
reading.
99.9 pct of the time i am using text, html -and jpeg files.
My main idea was to give the contents of a file a very short living time.

That was just an example to illustrate my point. The fact remains what you're describing is DRM. So you'd really need to wrap the files up in some other format to enforce this.
