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.
GUIs are very limiting. You’re only able to do what the designer wants you to be able to. By using the terminal it’s much simpler to do more complicated tasks (once you’ve gotten past the learning curve).
Also since so many servers are headless (no display outputs) they’ll be remotely logged into, meaning there’s only a terminal to interface with the machine.
