# pagesize(1)

Print supported system page sizes

## NAME

pagesize - Print supported system page sizes

## SYNOPSIS

**pagesize \[options\]**

## DESCRIPTION

The pagesize utility prints the page sizes of a page of memory in bytes, as returned by [getpagesizes(3)](/getpagesizes/3.md). This is useful when creating portable shell scripts, configuring huge page pools with hugeadm or launching applications to use huge pages with hugectl.

If no parameters are specified, **pagesize** prints the system base page size as returned by **getpagesize()**. The following parameters affect what other pagesizes are displayed.

- **--huge-only, -H**

  Display all huge pages supported by the system as returned by **gethugepagesizes()**.

- **--all, -a**

  Display all page sizes supported by the system.
