NAME
       ldd - print shared library dependencies

SYNOPSIS
       ldd [OPTION]... FILE...

DESCRIPTION
       ldd prints the shared libraries required by each program or shared library specified on the command line.

OPTIONS
       --version
              Print the version number of ldd.

       -v --verbose
              Print all information, including, for example, symbol versioning information.

       -u --unused
              Print unused direct dependencies.  (Since glibc 2.3.4.)

       -d --data-relocs
              Perform relocations and report any missing objects (ELF only).

       -r --function-relocs
              Perform relocations for both data objects and functions, and report any missing objects or functions (ELF only).

       --help Usage information.

NOTES
       The  standard  version  of  ldd comes with glibc2.  Libc5 came with an older version, still present on some systems.  The
       long options are not supported 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 "./".

BUGS
       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.
