本文介绍了Unix程序设计的多个基本原则，包括模块化、清晰性、组合性等，旨在帮助程序员写出更简洁、高效且易于维护的代码。

我比较崇尚的Unix程序设计哲学。摘自< Art of Unix Programming>

Rule of Modularity : Write simple parts connected by clean interfaces.
Rule of Clarity : Clarity is better than cleverness.
Rule of Composition : Design programs to be connected to other programs.
Rule of Separation : Separate policy from mechanism; separate interfaces from engines.
Rule of Simplicity : Design for simplicity; add complexity only where you must.
Rule of Parsimony : Write a big program only when it is clear by demonstration that nothing else will do.
Rule of Transparency : Design for visibility to make inspection and debugging easier.
Rule of Robustness : Robustness is the child of transparency and simplicity.
Rule of Representation : Fold knowledge into data so program logic can be stupid and robust.
Rule of Least Surprise : In interface design, always do the least surprising thing.
Rule of Silence : When a program has nothing surprising to say, it should say nothing.
Rule of Repair : When you must fail, fail noisily and as soon as possible.
Rule of Economy : Programmer time is expensive; conserve it in preference to machine time.
Rule of Generation : Avoid hand-hacking; write programs to write programs when you can.
Rule of Optimization : Prototype before polishing. Get it working before you optimize it.
Rule of Diversity : Distrust all claims for "one true way".
Rule of Extensibility: Design for the future, because it will be here sooner than you think.
