How can it not be true though? Terminal shines when you chain together more than one operation.
Imagine doing this in a GUI: list the files in a large directory, ignore the ones with underscores in them, find the biggest file, read the last 1000 lines from it and count the number of lines containing a particular string.
Thats a couple of pretty straightforward commands in a terminal, could take 30s for an experienced terminal user. Or the same task could take many minutes of manual effort stuffing round with multiple GUI applications.
I’m certain that I do tasks like that (ad hoc ones, not worth writing dedicated software for) tens of times in a typical work day. And I have no idea how GUI users can be even remotely productive.
I had to help my sister keep her 8 year old Mac going or buy a new secondhand (cheap) machine. With the options out there and with the state of Windows, I didn’t even consider it.
She’s ended up with her same 8 year old Mac with Ubuntu 24.04, and I’ve been really impressed with how it’s actually great for non-technical users these days! And works really well on old hardware.
This should give her another few years of life out of the thing without worrying about software support.
