User Commands size(1)
NAME
size - print section sizes in bytes of object files
SYNOPSIS
size [-f] [-F] [-n] [-o] [-V] [-x] filename...
DESCRIPTION
The size command produces segment or section size informa-
tion in bytes for each loaded section in ELF object files.
size prints out the size of the text, data, and bss (unini-
tialized data) segments (or sections) and their total.
size processes ELF object files entered on the command line.
If an archive file is input to the size command, the infor-
mation for each object file in the archive is displayed.
When calculating segment information, the size command
prints out the total file size of the non-writable segments,
the total file size of the writable segments, and the total
memory size of the writable segments minus the total file
size of the writable segments.
If it cannot calculate segment information, size calculates
section information. When calculating section information,
it prints out the total size of sections that are allocat-
able, non-writable, and not NOBITS, the total size of the
sections that are allocatable, writable, and not NOBITS,
and the total size of the writable sections of type NOBITS.
NOBITS sections do not actually take up space in the
filename.
If size cannot calculate either segment or section informa-
tion, it prints an error message and stops processing the
file.
OPTIONS
The following options are supported:
-f Prints out the size of each allocatable section,
the name of the section, and the total of the sec-
tion sizes. If there is no section data, size
prints out an error message and stops processing
the file.
-F Prints out the size of each loadable segment, the
permission flags of the segment, then the total of
the loadable segment sizes. If there is no segment
data, size prints an error message and stops pro-
cessing the file.
-n Prints out non-loadable segment or non-allocatable
section sizes. If segment data exists, size prints
out the memory size of each loadable segment or
file size of each non-loadable segment, the permis-
sion flags, and the total size of the segments. If
there is no segment data, size prints out, for each
allocatable and non-allocatable section, the memory
size, the section name, and the total size of the
sections. If there is no segment or section data,
size prints an error message and stops processing.
-o Prints numbers in octal, not decimal.
-V Prints the version information for the size command
on the standard error output.
-x Prints numbers in hexadecimal, not decimal.
EXAMPLES
The examples below are typical size output.
Example 1: Producing size information
example% size filename
2724 + 88 + 0 = 2812
Example 2: Producing allocatable section size information
example% size -f filename
26(.text) + 5(.init) + 5(.fini) = 36
Example 3: Producing loadable segment size information
example% size -F filename
2724(r-x) + 88(rwx) + 0(rwx) = 2812 ... (If statically linked)

NOTES
Since the size of bss sections is not known until link-edit
time, the size command will not give the true total size of
pre-linked objects.
