NAME
     ldd -- list dynamic object	dependencies

SYNOPSIS
     ldd [-a] [-v] [-f format] program ...

DESCRIPTION
     The ldd utility displays all shared objects that are needed to run	the
     given program or to load the given	shared object.	Contrary to nm(1), the
     list includes ``indirect''	dependencies that are the result of needed
     shared objects which themselves depend on yet other shared	objects.

     Zero, one or two -f options may be	given.	The argument is	a format
     string passed to rtld(1) and allows customization of ldd's	output.	 If
     one is given, it sets LD_TRACE_LOADED_OBJECTS_FMT1.  If two are given,
     they set LD_TRACE_LOADED_OBJECTS_FMT1 and LD_TRACE_LOADED_OBJECTS_FMT2,
     respectively.  See	rtld(1)	for details, including a list of recognized
     conversion	characters.

     The -a option displays the	list of	all objects that are needed by each
     loaded object.  This option does not work with a.out(5) binaries.

     The -v option displays a verbose listing of the dynamic linking headers
     encoded in	the executable.	 See the source	code and include files for the
     definitive	meaning	of all the fields.

EXAMPLES
     The following is an example of a shell pipeline which uses	the -f option.
     It	will print a report of all ELF binaries	in the current directory,
     which link	against	libc.so.6:
	   find	. -type	f | xargs -n1 file -F '	' | grep ELF | cut -f1 -d' ' |
	   xargs ldd -f	'%A %o\n' | grep libc.so.6

     ld(1), nm(1), rtld(1)

HISTORY
     A ldd utility first appeared in SunOS 4.0,	it appeared in its current
     form in FreeBSD 1.1.

     The -v support is based on	code written by	John Polstra <jdp@polstra.com>
