SIZE(1) General Commands Manual SIZE(1)NAME
size - print the size of the sections in an object file
size [ option ... ] [ object ... ]
Size (without the -m option) prints the (decimal) number of bytes required by the __TEXT, __DATA and __OBJC segments. All other segments
are totaled and that size is listed in the `others' column. The final two columns is the sum in decimal and hexadecimal. If no file is
specified, a.out is used.
The options to size(1) are:
- Treat the remaining arguments as name of object files not options to size(1).
-m Print the sizes of the Mach-O segments and sections as well as the total sizes of the sections in each segment and the total size of
the segments in the file.
-l When used with the -m option, also print the addresses and offsets of the sections and segments.
-x When used with the -m option, print the values in hexadecimal (with leading 0x's) rather than decimal.
Specifies the architecture, arch_type, of the file for size(1) to operate on when the file is a fat file. (See arch(3) for the cur-
rently know arch_types.) The arch_type can be "all" to operate on all architectures in the file. The default is to display only
the host architecture, if the file contains it; otherwise, all architectures in the file are shown.

The size of common symbols can't be reflected in any of the numbers for relocatable object files.

size(1) User Commands size(1)NAME
size - print section sizes in bytes of object files
size [-f] [-F] [-n] [-o] [-V] [-x] filename...
The size command produces segment or section size information in bytes for each loaded section in ELF object files. size prints out the
size of the text, data, and bss (uninitialized 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 information 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 allocatable, 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 information, it prints an error message and stops processing the file.
The following options are supported:
-f Prints out the size of each allocatable section, the name of the section, and the total of the section 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 processing 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 permission 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.
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)

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.
