# fallocate
|
|
|
|
> Reserve or deallocate disk space to files.
|
|
> The utility allocates space without zeroing.

|
- Reserve a file taking up 700 MiB of disk space:
|
|
|
|
`fallocate --length {{700M}} {{path/to/file}}`
|
|
|
|
- Shrink an already allocated file by 200 MiB:
|
|
|
|
`fallocate --collapse-range --length {{200M}} {{path/to/file}}`
|
|
|
|
- Shrink 20 MB of space after 100 MiB in a file:
|
|
|
|
`fallocate --collapse-range --offset {{100M}} --length {{20M}} {{path/to/file}}`
