size


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 sec-
              tion 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 pro-
              cessing 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 permis-
              sion 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 ... (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.
