size - list section sizes and total size of binary files

[objfile...]
The GNU size utility lists the section sizes and the total size
for each of the binary files objfile on its argument list. By
default, one line of output is generated for each file or each
module if the file is an archive.
objfile... are the files to be examined. If none are specified,
the file "a.out" will be used instead.
The command-line options have the following meanings:
-A
-B
-G
--format=compatibility
Using one of these options, you can choose whether the output
from GNU size resembles output from System V size (using -A,
or --format=sysv), or Berkeley size (using -B, or
--format=berkeley). The default is the one-line format
similar to Berkeley's. Alternatively, you can choose the GNU
format output (using -G, or --format=gnu), this is similar to
Berkeley's output format, but sizes are counted differently.
Here is an example of the Berkeley (default) format of output
from size:
$ size --format=Berkeley ranlib size
text data bss dec hex filename
294880 81920 11592 388392 5ed28 ranlib
294880 81920 11888 388688 5ee50 size
The Berkeley style output counts read only data in the "text"
column, not in the "data" column, the "dec" and "hex" columns
both display the sum of the "text", "data", and "bss" columns
in decimal and hexadecimal respectively.
The GNU format counts read only data in the "data" column,
not the "text" column, and only displays the sum of the
"text", "data", and "bss" columns once, in the "total"
column. The --radix option can be used to change the number
base for all columns. Here is the same data displayed with
GNU conventions:
$ size --format=GNU ranlib size
text data bss total filename
279880 96920 11592 388392 ranlib
279880 96920 11888 388688 size
This is the same data, but displayed closer to System V
conventions:
$ size --format=SysV ranlib size
ranlib :
section size addr
.text 294880 8192
.data 81920 303104
.bss 11592 385024
Total 388392
size :
section size addr
.text 294880 8192
.data 81920 303104
.bss 11888 385024
Total 388688
--help
-h
-H
-? Show a summary of acceptable arguments and options.
-d
-o
-x
--radix=number
Using one of these options, you can control whether the size
of each section is given in decimal (-d, or --radix=10);
octal (-o, or --radix=8); or hexadecimal (-x, or --radix=16).
In --radix=number, only the three values (8, 10, 16) are
supported. The total size is always given in two radices;
decimal and hexadecimal for -d or -x output, or octal and
hexadecimal if you're using -o.
--common
Print total size of common symbols in each file. When using
Berkeley or GNU format these are included in the bss size.
-t
--totals
Show totals of all objects listed (Berkeley or GNU format
mode only).
--target=bfdname
Specify that the object-code format for objfile is bfdname.
This option may not be necessary; size can automatically
recognize many formats.
-v
-V
--version
Display the version number of size.
-f Ignored. This option is used by other versions of the size
program, but it is not supported by the GNU Binutils version.
@file
Read command-line options from file. The options read are
inserted in place of the original @file option. If file does
not exist, or cannot be read, then the option will be treated
literally, and not removed.
Options in file are separated by whitespace. A whitespace
character may be included in an option by surrounding the
entire option in either single or double quotes. Any
character (including a backslash) may be included by
prefixing the character to be included with a backslash. The
file may itself contain additional @file options; any such
options will be processed recursively.
