.Sh NAME
.Nm ldd
.Nd list dynamic object dependencies
.Sh SYNOPSIS
.Nm
.Op Fl v
.Op Fl f Ar format
.Ar program ...
.Sh DESCRIPTION
.Nm
displays all shared objects that are needed to run the given program.
Contrary to
.Xr nm 1 ,
the list includes
.Dq indirect
dependencies that are the result of needed shared objects which themselves
depend on yet other shared objects.
.Pp
Zero, one or two
.Fl f
options may be given.
The argument is a format string passed to
.Xr rtld 1
and allows customization of
.Nm Ns 's
output.
See
.Xr rtld 1
for a list of recognized conversion characters.
.Pp
The
.Fl v
option displays an 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.

.Sh HISTORY
A
.Nm
utility first appeared in SunOS 4.0, it appeared in its current form in
.Fx 1.1 .
.Pp
The
.Fl v
support is based on code written by
