NAME
     size -- display section sizes and total size of ELF objects

SYNOPSIS
     size [--format=format] [--help] [--radix=radix] [--totals] [--version] [-ABVdhotx] [file ...]

DESCRIPTION
     The size utility lists the sizes of ELF sections, and optionally the total size, for each input file specified on the command line.  The size
     utility can operate on ELF objects, on ar(1) archives containing ELF objects, and on core dumps.  If no file name is specified on the com-
     mand-line, a.out is assumed.

     The size utility recognized the following options:

     --format=format
	     Display output using the format specified by argument format.  Supported values for this argument are: 'berkeley' and 'sysv'.  The
	     default output format is 'berkeley'.  See Display Formats below for more information.

     --help  Display a help message and exit.

     --radix=radix
	     Display numeric values using the radix specified by argument radix.  Supported values for radix are 8, 10 and 16.	The default radix
	     is 10.

     --totals
	     Shows cumulative totals of section sizes from all objects.  This option is ignored for System V style output.

     --version
	     Display a version identifier and exit.

     -A      Equivalent to specifying option --format=sysv.

     -B      Equivalent to specifying option --format=berkeley.

     -V      Equivalent to specifying option --version.

     -d      Equivalent to specifying option --radix=10.

     -h      Equivalent to specifying option --help.

     -o      Equivalent to specifying option --radix=8.

     -t      Equivalent to specifying option --totals.

     -x      Equivalent to specifying option --radix=16.

DISPLAY FORMATS
   Berkeley Style Output
     If 'berkeley' style output is in effect, an initial header line naming fields will be output, followed by one line of output for each ELF
     object specified on the command line or found in an archive.

     Each line will contain the following whitespace separated fields in order:
     1.   The size of the text segment in the object.
     2.   The size of the data segment in the object.
     3.   The size of the 'bss' segment in the object.
     4.   The total size of the object in either decimal or octal.  Decimal output is used if the specified output radix for numeric values is 10
	  or 16.  Octal output is used if the radix being used for numeric values is 8.
     5.   The total size of the object in hexadecimal.
     6.   The file name of the object.

     If option --totals was specified, an additional line in the same format as above will be output at the end containing the sum of the respec-
     tive fields.  The file name field for the line will contain the string '(TOTALS)'.

   System V Style Output
     If System V style output is selected, size will output the following information for each object:
     1.   The name of the object followed by a colon.
     2.   A header line containing the names of fields of subsequent lines.
     3.   One line per section present in the object.  Each line has three fields:
	  1.   The name of the section.
	  2.   Its size, in the selected radix for numeric values.
	  3.   The address associated with the section, in the selected numeric radix.
     4.   A line whose section name field contains the string 'Total' and whose size field contains the sum of all reported section sizes.

EXIT STATUS
     The size utility exits 0 on success, and >0 if an error occurs.

EXAMPLES
     To display the section sizes for /bin/ls use:

     $ size /bin/ls
     text	data	   bss	      dec	 hex	    filename
     20975	540	   392	      21907	 5593	     /bin/ls

     To display sizes and total for /bin/ls and /bin/dd in hexadecimal, use:

     $ size -tx /bin/ls /bin/dd
     text	data	   bss	      dec	 hex	    filename
     0x51ef	0x21c	   0x188      21907	 5593	     /bin/ls
     0x3df5	0x170	   0x200      16741	 4165	     /bin/dd
     0x8fe4	0x38c	   0x388      38648	 96f8	    (TOTALS)

     To display section sizes for /bin/ls in System V format use:

     $ size -A /bin/ls
     /bin/ls  :
     section		size	   addr
     .interp		21	   4194704
     .note.ABI-tag	24	   4194728
     .hash		624	   4194752
     .dynsym		2088	   4195376
     .dynstr		810	   4197464
     .rela.dyn		120	   4198280
     .rela.plt		1656	   4198400
     .init		19	   4200056
     .plt		1120	   4200076
     .text		15224	   4201200
     .fini		14	   4216424
     .rodata		1472	   4216448
     .data		80	   5267456
     .eh_frame		1624	   5267536
     .dynamic		384	   5269160
     .ctors		16	   5269544
     .dtors		16	   5269560
     .jcr		8	   5269576
     .got		576	   5269584
     .bss		528	   5270176
     .comment		686	   0
     Total		27110
