You should be able to look up everything I have in the code, but if anything is particularly confusing just let me know and I will try to explain :)

What I already learned from it, is that it is much more transparent to use a here document, if I want to combine tags/text with variable contens!

In my everyday life I don't use programming.

Something I could do is maintain a blog in PHP and CSS. I use wordpress but i consider it bloated for the tiny clean design I need. It's only advantage is the inbuild adaptability to different devices.

And the bash thing for occasional minor operations and tasks.

But due to lack of neccessity I have a low potential for programming in general anyway.

PS: Otherwise one hast to study the advanced bash scripting guide to learn enough of the whole structure.
