Examples
Set a size of 10 GB to an existing file, or create a new file with the specified size:
truncate {{[-s|--size]}} 10G {{path/to/file}}
Extend the file size by 50 MiB, fill with holes (which reads as zero bytes):
truncate {{[-s|--size]}} +50M {{path/to/file}}
Shrink the file by 2 GiB, by removing data from the end of file:
truncate {{[-s|--size]}} -2G {{path/to/file}}
Empty the file's content:
truncate {{[-s|--size]}} 0 {{path/to/file}}
Empty the file's content, but do not create the file if it does not exist:
truncate {{[-cs|--no-create --size]}} 0 {{path/to/file}}
