thanks a lot, will go through and get back to you if I have clarifications :) some suggestions if I may: * could you add your website to your HN profile? https://news.ycombinator.com/user?id=acidburnNSA https://news.ycombinator.com/user?id=acidburnNSA - makes it easier to know about it, that was where I looked up first before commenting in this thread * just saw about your book on the website... for the regex video showcase, I see that you are using double quotes - I'd suggest to always use single quotes unless you need double quotes (see https://mywiki.wooledge.org/Quotes https://mywiki.wooledge.org/Quotes and https://stackoverflow.com/questions/7680504/sed-substitution-with-bash-variables https://stackoverflow.com/questions/7680504/sed-substitution...) as double quotes are interpreted by the shell before it is passed to the command the topics covered in your book are super interesting and make for a nice workshop, will check it out :)
