Re: Help - Adding size to a document? -> No security, think differently
(I send direct reply to OP and Ubuntu intentionally with reason... I am
afraid message from OP may spread a wrong idea.)
I know double posting to ML (Debian and Ubuntu in this case.) is not
generally considered good. If the original poster uses Ubuntu, he
should post there only.

Although I do not agree his method to be valid one, one can create big
3GB random file by:
$ dd if=/dev/urandom of=random.bin bs=1024 count=$((3*1024*1024))
For random text file with about 3GB:
$ dd if=/dev/urandom bs=1024 count=$((1024*1024)) 2>/dev/null | od -t x1 - > random.txt
But if a hacker roots a badly configured system, he can use the
extraction utility to remove junk big one and get files he need.
What one should use is good security measures:
* well configured system to protect system.
* data encryption technology to make is useless even if a file is stolen.
