  • Learned bash heredoc 'read' and 'tr' commands and improved my script to create new posts

    My original script to automate the generation of new posts for this blog was done through a single line cmd that was a little bit complicated, because I’d have to rely on memory to figure out the order of the commands.

So I came across these two commands that helped me achieve the results I wanted: ‘read’ will (with options ‘-e’ and ‘-p’) prompt the user for the variables I need (date, title, category, text), and ‘tr’ helps replacing spaces with hiphens to create a short title for the filename. The improved script can be found here.
