Creating Fixed size file on unix

[avsrini]

Hi All,
I remember, there is a utility in hpux to
create fixed size file with no data. Typically,
we use this to do some testings. Now i forgot
that utility. Anybody got a idea, what utility/command is that ??!!

Thanks in advance
Srini

I think 'prealloc' is what you are looking for.

# man prealloc

For more information

prealloc is the command alright. Just make sure you don't run into a problem with ulimit. There is a note about this in the man page.

thanks for the info Patrick. Keep up

Regards
Srini.
