ldd - print shared library dependencies
ldd [OPTION]... FILE...
ldd prints the shared libraries required by each program or shared
library specified on the command line.
Print the version number of ldd.
Print all information, including e.g. symbol versioning informa-
Print unused direct dependencies.

--help Usage information.
The standard version of ldd comes with glibc2. Libc5 came with an older
version, still present on some systems. The long options are not sup-
ported by the libc5 version. On the other hand, the glibc2 version
does not support -V and only has the equivalent --version.
The libc5 version of this program will use the name of a library given
on the command line as-is when it contains a '/'; otherwise it searches
for the library in the standard locations. To run it on a shared
library in the current directory, prefix the name with "./".
ldd does not work on a.out shared libraries.
ldd does not work with some extremely old a.out programs which were
built before ldd support was added to the compiler releases. If you
use ldd on one of these programs, the program will attempt to run with
argc = 0 and the results will be unpredictable.
