How to look what an executable does...

I use both 'strace' and 'lsof' to get an insight into what
system resources my gcj programs are using.
strace will let you watch the system calls that your program is making
displaying the names of the calls and the arguments passed in.
If you use the strace '-p <pid>' option you can get strace to display
the system calls an already running program is making. This is real 
handy if the program
you want to monitor is a demon.
'lsof' will display names of files and network sockets that a program
currently has open.
