SIZE(1)			    General Commands Manual		       SIZE(1)

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
       command-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 de-
	       fault 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  ob-
       ject specified on the command line or found in an archive.

       Each line will contain the following whitespace separated fields	in or-
       der:
       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  nu-
	    meric 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 respective
       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  nu-
		 meric 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
