ldd equivalent on Mac OSX

zsh: command not found: ldd

Macだと代わりにotoolというコマンドがあるらしい。

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:

lddと同じように使う場合は-Lオプションをつける。
