The GNU size utility lists the section sizes---and the total
size---for each of the object or archive files objfile in its
argument list. By default, one line of output is generated for each
object file or each module in an archive.
objfile... are the object files to be examined.
If none are specified, the file "a.out" will be used.
The command line options have the following meanings:
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
Here is an example of the Berkeley (default) format of output from
$ size --format=Berkeley ranlib size
text data bss dec hex filename
294880 81920 11592 388392 5ed28 ranlib
294880 81920 11888 388688 5ee50 size
This is the same data, but displayed closer to System V conventions:
Show a summary of acceptable arguments and options.
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.
Print total size of common symbols in each file. When using Berkeley
format these are included in the bss size.
Show totals of all objects listed (Berkeley format listing mode only).
Specify that the object-code format for objfile is
bfdname. This option may not be necessary; size can
automatically recognize many formats.
Display the version number of size.
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.
