Help !!! Need to fill a filesystem 1

[drathbone]

Hi,

I have a disk thats been newfs'd and I need to check if it's faulty or not.

Ideally I need to write a script to create a large file (about 4gb) and then delete it, and then loop the process.

Any ideas of the best way to create the large file ???


Many thanks,
Darren

Use mkfile.

* mkfile [ -nv ] size [ k | b | m ] filename

This would make a 4GB file called temp1:

>mkfile 4096m temp1

If you want to fill the file, you can use /dev/zero which contains an infinite number of zeroes.

You can use dd to copy from /dev/zero to your new files

e.g. dd if=/dev/zero of=myfile bs=blocksize count=number of blocks

set bs and count to suitable values to give you a 4gb file.
