SIZE(1) General Commands Manual SIZE(1)NAME
size - print the size of the sections in an object file
SYNOPSIS
size [ option ... ] [ object ... ]
DESCRIPTION
Size (without the -m option) prints the (decimal) number of bytes required by the __TEXT, __DATA and __OBJC segments. All other segments
are totaled and that size is listed in the `others' column. The final two columns is the sum in decimal and hexadecimal. If no file is
specified, a.out is used.
The options to size(1) are:
- Treat the remaining arguments as name of object files not options to size(1).
-m Print the sizes of the Mach-O segments and sections as well as the total sizes of the sections in each segment and the total size of
the segments in the file.
-l When used with the -m option, also print the addresses and offsets of the sections and segments.
-x When used with the -m option, print the values in hexadecimal (with leading 0x's) rather than decimal.
-arch arch_type
Specifies the architecture, arch_type, of the file for size(1) to operate on when the file is a fat file. (See arch(3) for the cur-
rently know arch_types.) The arch_type can be "all" to operate on all architectures in the file. The default is to display only
the host architecture, if the file contains it; otherwise, all architectures in the file are shown.

The size of common symbols can't be reflected in any of the numbers for relocatable object files.

OTOOL(1) General Commands Manual OTOOL(1)NAME
otool - object file displaying tool
SYNOPSIS
otool [ option ... ] [ file ... ]
DESCRIPTION
The otool command displays specified parts of object files or libraries. If the, -m option is not used, the file arguments may be of the
form libx.a(foo.o), to request information about only that object file and not the entire library. (Typically this argument must be
quoted, ``libx.a(foo.o)'', to get it past the shell.) Otool understands both Mach-O (Mach object) files and universal file formats. Otool
can display the specified information in either its raw (numeric) form (without the -v flag), or in a symbolic form using macro names of
constants, etc. (with the -v or -V flag).
At least one of the following options must be specified:
-a Display the archive header, if the file is an archive.
-S Display the contents of the `__.SYMDEF' file, if the file is an archive.
-f Display the universal headers.
-h Display the Mach header.
-l Display the load commands.
-L Display the names and version numbers of the shared libraries that the object file uses.
-D Display just install name of a shared library.
-s segname sectname
Display the contents of the section (segname,sectname). If the -v flag is specified, the section is displayed as its type, unless
the type is zero (the section header flags). Also the sections (__OBJC,__protocol), (__OBJC,__string_object) and (__OBJC,__run-
time_setup) are displayed symbolically if the -v flag is specified.
-t Display the contents of the (__TEXT,__text) section. With the -v flag, this disassembles the text. And with -V, it also symboli-
cally disassembles the operands.
-d Display the contents of the (__DATA,__data) section.
-o Display the contents of the __OBJC segment used by the Objective-C run-time system.
-r Display the relocation entries.
-c Display the argument strings (argv[] and envp[]) from a core file.
-I Display the indirect symbol table.
-T Display the table of contents for a dynamically linked shared library.
-R Display the reference table of a dynamically linked shared library.
-M Display the module table of a dynamically linked shared library.
-H Display the two-level namespace hints table.
The following options may also be given:
-p name
Used with the -t and -v or -V options to start the disassembly from symbol name and continue to the end of the (__TEXT,__text) sec-
tion.
-v Display verbosely (symbolically) when possible.
-V Display the disassembled operands symbolically (this implies the -v option). This is useful with the -t option.
-X Don't display leading addresses when displaying contents of sections.
-arch arch_type
Specifies the architecture, arch_type, of the file for otool(1) to operate on when the file is a universal file. (See arch(3) for
the currently know arch_types.) The arch_type can be "all" to operate on all architectures in the file. The default is to display
only the host architecture, if the file contains it; otherwise, all architectures in the file are shown.
-m The object file names are not assumed to be in the archive(member) syntax, which allows file names containing parenthesis.
