Run strace [arguments to strace] your_program [arguments to your program]

Strace is great at seeing system calls. Once you understand how this works, be sure to check out ltrace , which shows the calls to dynamically linked libraries.

Together they give you a very good idea of ​​what any given program does (unless statically linked, of course).
