6. size

size [ -A | -B | --format=compatibility ] [ --help ] [ -d | -o | -x | --radix=number ] [ --target=bfdname ] [ -V | --version ] [ objfile... ]

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:

-A

-B

--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.

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

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

-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'.

--target=bfdname

Specify that the object-code format for objfile is bfdname. This option may not be necessary; size can automatically recognize many formats. See section 15.1 Target Selection, for more information.

-V

--version

Display the version number of size.
