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.

       -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,__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.  And with -V, it also sym-
              bolically 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.

       -r     Display the relocation entries.

       -c     Display  the  argument  strings  (argv[] and envp[]) from a core

       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 display leading addresses when displaying contents of sec-
              tions.

       -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(mem-
              ber) syntax, which allows file names containing parenthesis.
