No, this will just tell you which symbols are in the binary.

This will give it to you, along with a lot of noise. For example,
$ strings /usr/local/bin/emacs | fgrep .so.
will give you each library twice, and uncounted instances of
libjspBsdx86.so.2.7.
It's nice to see people making suggestions, but for your own sakes,
why don't you try them first?
