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  informa-
     tion  in  bytes for each loaded section in ELF object files.
     size prints out  the size of the text, data, and bss (unini-
     tialized 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 infor-
     mation 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  allocat-
     able,   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  informa-
     tion,  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 per-
           mission   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 sec-
           tion  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 ... (If statically linked)

NOTES

     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.
