True of course. If you look at my comment though, I haven’t said that speed is the point of the command line. Just that Linux users are obsessed with it. For most users most of the time, the repetition/automation is not the point and ability to write scripts is not the most important thing. And you can combine tools with GUIs as well, it’s just slower. Same with reliability, GUIs don’t have to be and usually aren’t unreliable, so command line only has the automation and speed going for it.
you only need to remember few letters of the command
I believe that is exactly the problem in this thread. The command history only works if you remember in the first place.
Of course, I didn’t make some kind of point about the general use of GUIs and CLIs, I just said that GUIs are much faster if you can’t remember commands, which is the problem in this thread.
