Linux/ FreeBSD GNU GCC Common option for C compiler

gcc is a GNU project C and C++ compiler for Linux, UNIX, FreeBSD etc. From the wikipedia:

GCC is a key component of the GNU toolchain. As well as being the official compiler of the GNU system, GCC has been adopted as the standard compiler by most other modern Unix-like computer operating systems, including Linux, the BSD family and Mac OS X. GCC has been ported to a wide variety of computer architectures, and is widely deployed as a tool in commercial and closed development environments.

Common gcc options:

cc -E :preprocessor
cc -S :create or show assembly coding
cc -o :object filename
cc -g :debug info
cc -O :optimized code
cc -O2 :optimized code with optimization level increased
cc -Wall :create or show all warning
cc -D_SYMBOL_ : Symbol for prerpcessor

You can use gcc instead of cc.
