Question

What command would you use to find out which libraries are linked to the /bin/znew executable program?

            When you ran this command what message did you receive on the console?

Answer 1

INFORMATION ABOUT: "ldd" command

* we can use ldd command to find out which shared libraries are linked to the executables.

* This ldd command invokes dynamic linker to find out library dependencies of an executable program.

> $ ldd /path/to/program

*Note:-This ldd command is NOT recommended to run with any untrusted third-party executable which can leads to security risks it directly invokes the executable to identify its library dependencies.

*we can use a safer way in order to know the dependencies of an unknown executable program use the following command.

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

On linux, we can use the following which works better than ldd when the executable uses a non-default loader.

lsof -P -T -p Application_PID.

These are some methods to know the libraries are linked to the executable programs. ;)

I am attaching the screenshots you can refer to them.
