@osanna Especially when you have commands. I was born with commands as I used ms-dos at the beginning of 90s. But now, I honestly prefer something semi-automated for the "dirty" activities, as for configuration files it's very difficult to find the issue if you have a conf file made of dozens of lines, a long serie of indentations, punctuation signs and apostrophes everywhere, just forget one and you are screwed.
I'm not saying it's impossible, I'm saying that this can take double time of work, than an ordinary sighted administrator. I'm somehow envious of those who create a self-host platform on their very own, starting from a blank page.
