<p>I'd like to know which libraries are used by executables on my system. More specifically, I'd like to rank which libraries are used the most, along with the binaries that use them. How can I do this?</p>

to learn what libraries a binary uses, use ldd
```
```
ldd path/to/the/tool
```
```
You'd have to write a little shell script to get to your system-wide breakdown.
