wp:The Unix Programming Environment
wp:Unix philosophy

    This is the Unix philosophy: Write programs that do one thing and do it
    well. Write programs to work together. Write programs to handle text
    streams, because that is a universal interface.

    The notion of "intricate and beautiful complexities" is almost an oxymoron.
    Unix programmers vie with each other for "simple and beautiful" honors — a
    point that's implicit in these rules, but is well worth making overt.

wp:Pipeline (Unix)

wp:Unix_philosophy#Mike_Gancarz:_The_UNIX_Philosophy

    Small is beautiful.
    Make each program do one thing well.
    Build a prototype as soon as possible.
    Choose portability over efficiency.
    Store data in flat text files.
    Use software leverage to your advantage.
    Use shell scripts to increase leverage and portability.
    Avoid captive user interfaces.
    Make every program a filter.

wp:Douglas McIlroy

    Those types are not "abstract"; they are as real as int and float.
    As a programmer, it is your job to put yourself out of business.
        What you do today can be automated tomorrow.
    Keep it simple, make it general, and make it intelligible.
    The real hero of programming is the one who writes negative code.
