pagesize Command

Purpose

Displays the system page size.

Syntax

pagesize [ -a ] [ -f ]

Description

The pagesize command prints the size, in bytes, of a page of memory, as returned by the getpagesize subroutine. Provided for system compatibility, this command is useful when constructing portable shell scripts.

If the -a flag is specified, the pagesize command prints all of the page size values (in bytes) supported on the system.

Flags

-a

Prints all of the page size values (in bytes) supported on the system.

-f

Prints the formatted page sizes with an alphabetical suffix rather than the page size in bytes (for example, 4K)

Example

1. To obtain the size system page, enter:

   pagesize

   The system returns the number of bytes, such as 4096.

2. To print the formatted page size, enter:

   pagesize -f

   The system returns the formatted page size (for example, 4K).

3. To print all of the supported page size with an alphabetical suffix, enter:

   pagesize -af

   The system returns all of the supported page sizes. For example:

   4K
   64K
   16M
