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 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. 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 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. 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 ...

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. SunOS 5.11 16 Oct 1996 size(1)

NAME
size - list section sizes and total size. SYNOPSIS
size [-A|-B|--format=compatibility] [--help] [-d|-o|-x|--radix=number] [--common] [-t|--totals] [--target=bfdname] [-V|--version] [objfile...] DESCRIPTION
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. OPTIONS
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 --help 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 format these are included in the bss size. -t --totals Show totals of all objects listed (Berkeley format listing 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 --version Display the version number of size. @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. SEE ALSO
