OTOOL(1)                                                              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 under-
       stands 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, as well as the shared library ID if
              the file is a shared library.

       -D     Display  just  the  install  name  of  a  shared  library.   See
              install_name_tool(1) for more info.

       -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,__runtime_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.  With the -V flag, it also
              symbolically disassembles the operands.

       -d     Display the contents of the (__DATA,__data) section.

       -o     Display the contents of the __OBJC segment used  by  the  Objec-
              tive-C run-time system.
  -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.

       -G     Display the data in code table.

       -C     Display  the  linker optimization hints (-v for verbose mode can
              also be added).

       -P     Print the info plist section, (__TEXT,__info_plist), as strings.

       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)
              section.

       -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 print leading addresses or  headers  with  disassembly  of
              sections.

       -q     Use the llvm disassembler when doing disassembly; this is avail-
              able for the x86 and arm architectures.  This is the default.

       -mcpu=arg
              When doing disassembly using the llvm disassembler use  the  cpu
              arg.

       -function_offsets
              When  doing  disassembly  print the decimal offset from the last
              label printed.

       -j     When doing disassembly print the opcode bytes  of  the  instruc-
              tions.

       -Q     Use otool(1)'s disassembler when doing disassembly.
-arch arch_type
              Specifies  the architecture, arch_type, of the file for otool(1)
              to operate on when the file is a universal file (aka a file with
              multiple  architectures).   (See arch(3) for the currently known
              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(mem-
              ber) syntax, which allows file names containing parenthesis.

       --version
              Print the otool(1) version information.
