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 ... (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.
