List Libraries

rz-bin can list libraries used by a binary with the -l option:

$ rz-bin -l `which rizin`

If you compare the outputs of rz-bin -l and ldd, you will notice that rz-bin lists fewer libraries than ldd. The reason is that rz-bin does not follow and does not show dependencies of libraries. Only direct binary dependencies are shown.
