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.
If you understand that the terminal is better in the long run then you answered your own question, most people who fiddle with servers do so for a long time so the time investment is worth it. A similar analogy is learning knife skills, if you just cook for yourself being able to chop an onion in seconds saves you a minute a day from the one onion you used, not really worth outside being a neat party trick. But if you work in a kitchen that’s mandatory, chopping an onion in seconds means you save an hour for the 60 onions you chop in preparation for the service. Same idea for GUIs/terminal, it has a higher learning curve but if you try to avoid the curve you’ll never be able to do it fast, so the time investment is worth it if you’re going to be doing this daily (like most server admins do)
