## Name

allocate - allocate memory

## Synopsis

```**sh
$ allocate [number [unit (B/KiB/MiB)]]
```

## Description

`allocate` allocates a specific amount of virtual memory (specified in `number` and `unit`, by default 50 MiB), It also writes to each allocated page and then sleeps for 10 seconds. It is primarily used to test the kernel's memory management capabilities.

## Arguments

* `number`: A number of `units` to allocate; the default is **50**
* `unit`: Data size unit, can be `B` (bytes), `KiB` (kibibytes) or `MiB` (mebibytes); the default is **MiB**
