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.
I’ve seen both. But typing in a command or writing it into a script or configuration file and then activating it for 80 servers is way faster and easier than logging in into everyone and clicking some menus and buttons with the mouse. Or you have mantenance every 2 weeks and it’s super easy to launch a prepared script instead of dragging and dropping files with the mouse for hours.
Also people vastly overestimate how difficult it is to use the command line. It needs a certain amount of knowledge, true. But it it is not a big deal compared to knowing the concepts behind your server, how a webserver or some network works etc.
Linux servers usually don’t have the graphical interface installed, because nobody bothers and it’d be a waste of space and time.
