具体描述：

ldd打印命令行上指定的每个程序或共享库所需的共享库。

安全问题：
In the usual case, ldd invokes the standard dynamic linker (see ld.so(8)) with the
LD_TRACE_LOADED_OBJECTS environment variable set to 1, which causes the linker to display
the library dependencies. Be aware, however, that in some circumstances, some versions of
ldd may attempt to obtain the dependency information by directly executing the program.
Thus, you should never employ ldd on an untrusted executable, since this may result in the
execution of arbitrary code. A safer alternative when dealing with untrusted executables
is:

$ objdump -p /path/to/program | grep NEEDED
