I have a terrible memory for code and often refer to the internet to jog my memory on how to perform even the simplest of operations, be it at the command line or with some other programming language.
Knowledge allows me to collect examples of how to do various things in a way that I find helpful and with a little luck, you might find something helpful in here too!
