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