ldd
TLDR
Display shared library dependencies
$ ldd /path/to/binary
Display all information about dependencies$ ldd -v /path/to/binary
Display unused direct dependencies$ ldd -u /path/to/binary
Report missing objects and perform data relocations$ ldd -d /path/to/binary
Report missing objects and perform function relocations$ ldd -r /path/to/binary
SYNOPSIS
ldd [option]... file...
DESCRIPTION
ldd prints the shared objects (shared libraries) required by each program or shared object on the command line. It identifies dependencies and displays their locations along with load addresses.
PARAMETERS
-v, --verbose
Print all information including symbol versioning-u, --unused
Print unused direct dependencies-d, --data-relocs
Perform data relocations and report missing objects (ELF only)-r, --function-relocs
Perform data and function relocations and report missing objects (ELF only)--version
Display version information--help
Display usage information
CAVEATS
Never run ldd on untrusted executables as it may execute arbitrary code. For untrusted binaries, use: objdump -p /path/to/program | grep NEEDED
HISTORY
ldd is part of the GNU C Library (glibc). It works by setting the LD_TRACE_LOADED_OBJECTS environment variable and invoking the dynamic linker.
