What do you think? <br>
Comments and other stories are appreciated.<br>
<br>
CLI is good, even superb when user either knows what commands to utter, <br>
or knows what questions to ask shell, so that it leads you toward <br>
correct action (assuming shell is capable of answering).<br>
<br>
GUI is the only option for those users who don't know what questions to <br>
ask. And designer has to lead user with clues. Clues are aided by common <br>
metaphors, common experience.<br>
<br>
lxc and docker are examples of CLI that was better at leading me to <br>
correct commands. Before that I wasn't touching CLI much. And in what I <br>
do now, I look and long for lxc/docker style of leading me, the user. <br>
Let's note that aforementioned stylistic approach in lxc/docker could've <br>
existed before, and I also don't want to say that this is the best, <br>
example is simply my anecdotal case of experience in cli.<br>
