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 fat 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  con-
       stants, 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 fat 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 fat 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.

NAME

       strings - find the printable strings in a object, or other binary, file

SYNOPSIS

       strings [ - ] [ -a ] [ -o ] [ -t format ] [ -number ] [ -n number ] [--] [file ...]

DESCRIPTION

       Strings	looks  for ASCII strings in a binary file or standard input.  Strings is useful for identifying random object files and many other
       things.	A string is any sequence of 4 (the default) or more printing characters ending with a newline or a null.  Unless  the  -  flag	is
       given,  strings	looks in all sections of the object files except the (__TEXT,__text) section.  If no files are specified standard input is
       read.

       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.   (Typ-
       ically this argument must be quoted, ``libx.a(foo.o)'', to get it past the shell.)

       The options to strings(1) are:

       -a     This option causes strings to look for strings in all sections of the object file (including the (__TEXT,__text) section.

       -      This option causes strings to look for strings in all bytes of the files (the default for non-object files).

       --     This option causes strings to treat all the following arguments as files.

       -o     Preceded each string by its offset in the file (in decimal).

       -t format
	      Write  each  string  preceded  by its byte offset from the start of the file.  The format shall be dependent on the single character
	      used as the format option-argument:

       d      The offset shall be written in decimal.

       o      The offset shall be written in octal.

       x      The offset shall be written in hexadecimal.

       -number
	      The decimal number is used as the minimum string length rather than the default of 4.

       -n number
	      Specify the minimum string length, where the number argument is a positive decimal integer. The default shall be 4.

       -arch arch_type
	      Specifies the architecture, arch_type, of the file for strings(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, which is the default.

BUGS

       The algorithm for identifying strings is extremely primitive.
