How to Create a Big file ?

[Hermann Merz_1]

Hi,
what?s the easiest way to create in a script one big file of, for example 50 MByte.
I want to delete this file if the FileSystem is full and recreate it when the Fileystem is empty (Oracle Archive Stuck).

best regards

The command you want is prealloc. To create a 50MB file called FILLER you would:

prealloc FILLER 50000000

Hello,

one thing that came to my mind is to just copy one of the bigger files from your system to that filesystem.
You could i.e. copy a /stand/vmunix file into that filesystem and name it something else. That file is usually pretty big.
