|
|
|
|
`truncate -s {{10G}} {{filename}}`
|
|
|
|
- Extend the file size by 50M, fill with holes (which reads as zero bytes):
|
|
|
|
`truncate -s +{{50M}} {{filename}}`
|
|
|
|
- Shrink the file by 2GiB, by removing data from the end of file:
|
|
|
|
`truncate -s -{{2G}} {{filename}}`
|
|
|
|
- Empty the file's content:
|
|
|
|
`truncate -s 0 {{filename}}`
