Reading and writing files is from the first requirement of programming. When it comes to a point you will probably have to code. When I started to computer engineering our first-week assignments include reading and writing from file and includes some calculations. From then in my jobs and project, i often need reading and writing from the filesystem. I genuinely love to use javascript. It’s my first personal choice for when I need to create some scripting solution for my tasks.

I sometimes struggle remembering simple commands and need to look some cheats sheet.These are the ones I have kept from the moment when started to using git. I started to learn git little bit late then others but after started to using git. I kept commands on my joplin book and I try to keep this gist updated. Maybe it can help you also.
