       size - list section sizes and total size of binary files

       size [-A|-B|-G|--format=compatibility]
            [--help]
            [-d|-o|-x|--radix=number]
            [--common]
            [-t|--totals]

            [objfile...]

DESCRIPTION

       The GNU size utility lists the section sizes and the total size for each of the binary files objfile on
       its argument list.  By default, one line of output is generated for each file or each module if the file
       is an archive.

       objfile... are the files to be examined.  If none are specified, the file "a.out" will be used instead.

OPTIONS

       The command-line options have the following meanings:

       -A
       -B
       -G
       --format=compatibility
           Using  one  of  these  options, you can choose whether the output from GNU size resembles output from
           System V size (using -A, or --format=sysv), or Berkeley size (using -B, or  --format=berkeley).   The
           default  is  the one-line format similar to Berkeley's.  Alternatively, you can choose the GNU format
           output (using -G, or --format=gnu), this is similar  to  Berkeley's  output  format,  but  sizes  are
           counted differently.

           Here is an example of the Berkeley (default) format of output from size:

                   $ size --format=Berkeley ranlib size
                      text    data     bss     dec     hex filename
                    294880   81920   11592  388392   5ed28 ranlib
                    294880   81920   11888  388688   5ee50 size

           The  Berkeley  style output counts read only data in the "text" column, not in the "data" column, the
           "dec" and "hex" columns both display the sum of the "text", "data", and "bss" columns in decimal  and
           hexadecimal respectively.

           The  GNU  format counts read only data in the "data" column, not the "text" column, and only displays
           the sum of the "text", "data", and "bss" columns once, in the "total" column.  The --radix option can
           be used to change the number base for all  columns.   Here  is  the  same  data  displayed  with  GNU
           conventions:

                   $ size --format=GNU ranlib size
                         text       data        bss      total filename
                       279880      96920      11592     388392 ranlib
                       279880      96920      11888     388688 size

           This is the same data, but displayed closer to System V conventions:

                   $ size --format=SysV ranlib size
                   ranlib  :
                   section         size         addr
                   .text         294880         8192
                   .data          81920       303104
                   .bss           11592       385024
                   Total         388392

                   size  :
                   section         size         addr
                   .text         294880         8192
                   .data          81920       303104
                   .bss           11888       385024
                   Total         388688

       --help
       -h
       -H
       -?  Show a summary of acceptable arguments and options.

       -d
       -o
       -x
       --radix=number
           Using one of these options, you can control whether the size of each section is given in decimal (-d,
           or  --radix=10);  octal  (-o,  or --radix=8); or hexadecimal (-x, or --radix=16).  In --radix=number,
           only the three values (8, 10, 16) are supported.  The total size is  always  given  in  two  radices;
           decimal and hexadecimal for -d or -x output, or octal and hexadecimal if you're using -o.

       --common
           Print  total  size  of  common  symbols  in  each  file.  When using Berkeley or GNU format these are
           included in the bss size.

       -t
       --totals
           Show totals of all objects listed (Berkeley or GNU format mode only).

       --target=bfdname
           Specify that the object-code format for objfile is bfdname.  This option may not be  necessary;  size
           can automatically recognize many formats.

       -v
       -V
       --version
           Display the version number of size.

       -f  Ignored.   This  option is used by other versions of the size program, but it is not supported by the
           GNU Binutils version.

       @file
           Read command-line options from file.  The options read are inserted in place of  the  original  @file
           option.   If  file  does not exist, or cannot be read, then the option will be treated literally, and
           not removed.

           Options in file are separated by whitespace.  A whitespace character may be included in an option  by
           surrounding  the  entire  option  in  either  single  or  double  quotes.  Any character (including a
           backslash) may be included by prefixing the character to be included with a backslash.  The file  may
           itself contain additional @file options; any such options will be processed recursively.
