# fallocate
|
|
|
|
> Reserve or deallocate disk space to files.
|
|
> The utility allocates space without zeroing.
|
|
|
|
- Reserve a file taking up 700MB of disk space:
|
|
|
|
`fallocate --length {{700M}} {{path/to/file}}`
|
|
|
|
- Shrink an already allocated file by 200MB:
|
|
|
|
`fallocate --collapse-range --length {{200M}} {{path/to/file}}`
|
|
|
|
- Shrink 20MB of space after 100MB in a file:
|
|
|
|
`fallocate --collapse-range --offset {{100M}} --length {{20M}} {{path/to/file}}`
