# create files of given size

```sh
# shrink or extend the size of a file to the specified size
truncate -s 10G foo
# preallocate or deallocate space to a file
fallocate -l 5G bar
```

given fs support `truncate` (coreutils) may create _sparse file_,
`fallocate` (util-linux) not, unless told to do so.
