How to create an large empty file on unix? (like with touch -size 4GB)
I need to take up space (4gigs) on purpose for testing purposes and would like to create a large (empty) file. I would like to know if there is a simple command that exists to do this (like "touch")?
I don't want to have to resort to copying a large file over the network, tarring a large dir, catting files, or any type of script to create a large file.
Any ideas?
