This dd command allows you to create an “empty” file of a specifically desired size. Creating these arbitrary heavy files, may be useful for testing purposes.
Use the command below:

dd if=/dev/zero of=testfile.test bs=1k count=1000

This command results in the creation of an empty 1GB file named testfile.test
(1000 represents 1000 blocks of 1Kb)
