            <p>The development of pipes in 1973 formalized the existing principle of stdin-stdout into a philosophy in Version 3 Unix, with older software rewritten to comply. Previously visible in early utilities such as wc, cat, and uniq, McIlroy cites Thompson's grep as what "ingrained the tools outlook irrevocably" in the operating system, with later tools like tr, m4, and sed imitating how grep transforms the input stream.[5]</p>
