Or is that more of a stereotype, and there are some (maybe more?) out there using some form of graphical interfaces/web dashboards/etc.?
It’s struck me as interesting how when you look up info about managing servers that they primarily go through command-line interfaces/terminals/etc. It’s made me wonder how much of that’s preference and how much of it’s an absence of graphical interfaces.
You can accomplish a lot through scripting - light programming. Anything you can type into a command line can also be executed by a script. This is the power of them. So when managing large arrays of resources, the potential for automation and scaling effort is big.
I don’t think all of that can be replaced with GUIs. When you consider that sysadmins are working with tons of different software from many different providers and trying to make it all work together, the command line interface is really the common language they all share - even the bulllshit legacy products that are still hanging around after 15 years of being outdated. You’d need extremely sophisticated GUI tools to be able to do everything, across all these products, at scale.
There are of course GUI tools for specific tasks, but the command line is the foundational tool.
