Oneliners
Learning to write bash oneliners is skill that pays incredible dividends over the course of career in software engineering or computer science. While individual oneliners usually tend to take on a life of their own, a few principles apply to nearly every oneliner.
I gave this talk at CMU as a part of the course 15-131 Great Practical Ideas for Computer Scientists. Since it was for a lecture, it splits its time beteween reviewing old material and introducing new material. Topics introduced include shell IO redirection, crafting bash oneliners iteratively, and some common tools that compose well in oneliners.
