For anyone interested in learning how to create their own Unix command-line tools (not just use them), feel free to check out these links to content by me (about doing such work in C and Python): 1) Developing a Linux command-line utility: an article I wrote for IBM developerWorks: https://jugad2.blogspot.com/2014/09/my-ibm-developerworks-article.html https://jugad2.blogspot.com/2014/09/my-ibm-developerworks-ar... Follow links in the article to go to the source code of the tool described in the tutorial, and the PDF of the IBM dW article. 2) My comment, here: https://news.ycombinator.com/item?id=19564706 https://news.ycombinator.com/item?id=19564706 on this HN thread: Ask HN: Looking for a series on implementing classic Unix tools from scratch: https://news.ycombinator.com/item?id=19560418 https://news.ycombinator.com/item?id=19560418
