6 size - print section sizes in bytes of object files

9 size [-f] [-F] [-n] [-o] [-V] [-x] filename...

13 The size command produces segment or section size information in bytes
14 for each loaded section in ELF object files. size prints out the size
15 of the text, data, and bss (uninitialized data) segments (or sections)
16 and their total.
17 size processes ELF object files entered on the command line. If an ar‐
20 chive file is input to the size command, the information for each
21 object file in the archive is displayed.
22 When calculating segment information, the size command prints out the
25 total file size of the non-writable segments, the total file size of
26 the writable segments, and the total memory size of the writable seg‐
27 ments minus the total file size of the writable segments.
28 If it cannot calculate segment information, size calculates section
31 information. When calculating section information, it prints out the
32 total size of sections that are allocatable, non-writable, and not
33 NOBITS, the total size of the sections that are allocatable, writable,
34 and not NOBITS, and the total size of the writable sections of type
35 NOBITS. NOBITS sections do not actually take up space in the filename.
36 If size cannot calculate either segment or section information, it
39 prints an error message and stops processing the file.
40
42 The following options are supported:
43 -f Prints out the size of each allocatable section, the name of the
45 section, and the total of the section sizes. If there is no sec‐
46 tion data, size prints out an error message and stops processing
47 the file.
48 -F Prints out the size of each loadable segment, the permission
51 flags of the segment, then the total of the loadable segment
52 sizes. If there is no segment data, size prints an error message
53 and stops processing the file.
54 -n Prints out non-loadable segment or non-allocatable section sizes.
57 If segment data exists, size prints out the memory size of each
58 loadable segment or file size of each non-loadable segment, the
59 permission flags, and the total size of the segments. If there is
60 no segment data, size prints out, for each allocatable and non-
61 allocatable section, the memory size, the section name, and the
62 total size of the sections. If there is no segment or section
63 data, size prints an error message and stops processing.
64 -o Prints numbers in octal, not decimal.
67 -V Prints the version information for the size command on the stan‐
70 dard error output.
71 -x Prints numbers in hexadecimal, not decimal.

77 The examples below are typical size output.
78 Example 1 Producing size information
80 example% size filename
82 2724 + 88 + 0 = 2812
83 Example 2 Producing allocatable section size information
87 example% size -f filename
89 26(.text) + 5(.init) + 5(.fini) = 36
90 Example 3 Producing loadable segment size information
94 example% size -F filename
96 2724(r-x) + 88(rwx) + 0(rwx) = 2812 ... (If statically linked)

116 Since the size of bss sections is not known until link-edit time, the
117 size command will not give the true total size of pre-linked objects.
