3/26/2023 0 Comments Editra run![]() Assumptions and Ground Rulesīefore jumping into editor options, I want to put down the assumptions I'm using in my selection of what editors to write about. ![]() Personally, I use a GUI editor or two when writing code and writing documents. A GUI editor can be advantageous if you are a visual person (like me), but it's not a requirement. You don't have to be an expert, but you do need to know enough commands to edit files and be comfortable with the editor.Īfter knowing and being comfortable with a command-line editor – enough that you can SSH to a server and edit a configuration file – you can either choose to learn a second graphical user interface (GUI) editor or not. Knowing how to use SSH and a command-line editor has saved my admin bacon on several occasions. I argue that systems administration in general, and HPC in particular, needs a command-line editor, because it can be used even if X Windows isn't working or isn't installed on the servers. Despite the risks, discussing editors is a useful, interesting, and worthwhile exercise. It's also the tool that will generate a tremendous amount of – shall we say – discussion, possibly resulting in the exchange of insults and general loathing of our fellow human beings. The editor can be one of the most important tools, if not the most important tool, for administrators of HPC systems. Today I thought I would steer away from hard-core high-performance computing (HPC) topics – but not too far – because I want to discuss options for a key critical HPC tool: the editor.
