Terminal-based substance editors similar Nano oregon little are importantly lighter than full-featured applications similar VS Code oregon LibreOffice. On older machines—especially those with accepted hard drives—using the terminal tin prevention clip and resources.
Finally, moving successful the terminal encourages a deeper knowing of however your strategy works. You'll people learn astir Linux record systems, permissions, and substance processing—concepts that often stay hidden erstwhile utilizing lone graphical interfaces. So, I wouldn't accidental a terminal is amended than a GUI, but if you are each successful to larn and research the satellite of computers and Linux systems, past it's champion to get utilized to with terminal.
