To date, I don't think anyone has written a written a good online tool for keeping track of misc command lines for various tasks on various systems. In order to understand this before attempting to write one, I thought I would start by listing particularly good commands I have seen to get some ideas for the layout of such a tool.
The purpose of such a tool would be to easily record common command lines (as easy as typing the command). Later, fill in detail that 'could' extend to other similar commands.
It begins with listing good examples of command line explanations so that I can understand how to define the table.
