Determining Section Sizes with size

Determining Section Sizes with size

The size tool prints information about the sections (such as text, rdata, and sbss) of the specified object or archive files. The elf(4) reference page describes the format of these sections.

size Syntax

The syntax for size is:

size options [filename1 filename2...filenamen]

options: Specifies the format of the listing (see Table 2-10).
filename: Specifies the object or archive files whose properties are to be listed. If you do not specify a filename, the default is a.out.

size Options

Table 2-10 lists size options. For more information, see the size(1) reference page.

size Options
Option Action
-A Prints data section headers in System V format (default).
-B Prints output in BSD-style format.
-d Prints sizes in decimal (default).
-f Prints data on allocatable sections including the size, permission flags, and the total of the loadable sizes.
-F Prints data on loadable segments including the name and the total of the section sizes.
-n Prints nonloadable and nonallocatable section sizes.
-o Prints sizes in octal.
-svr4 Prints output in SVR4-style format.
-V Prints the version of size that you are using.
-x Prints sizes in hexadecimal.
