SIZE(1)                 FreeBSD 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 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 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
               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:
