    I totally agree on command line. I only use it for a couple of things, related to installing updates. The rest of the time I prefer to have a GUI tool. Fortunately, there are many available now.

    I actually have a fair bit of experience working within the command prompt. I had to learn pretty quick when I was working on a server system that was never properly maintained.

    EXT4 is a filesystem used to access the hard drive. It is selected and installed during initial install of the Operating System itself, when the hard drive is formatted.

    https://opensource.com/article/17/5/introduction-ext4-filesystem

    There are many filesystems available. I have, on different hard drives and on different machines, EXT4 and BTRFS (b-tree file system).

    RE Ext4 filesystem. It is NOT the newest file system, but it is "tried and tested". That means it is less likely to run into any problems caused by software incompatibility. I've been using it for a decade, before that I used EXT3, its precursor.

    Never had any problems relating to the filesystem itself. I have lost hard drives when, for example, I carried a desktop on my bike (bouncing the magnetic heads is NOT good) but that is a physical failure, not file system related. EXT4 tried to correct for that damage and the drive kept working until the sector errors exceeded the remaining disk space. I still have that drive, does anyone need a door stop?

    Right now, I'm testing the BTRFS (b-tree file system) on a weak and old system (Gateway desktop with only 3GB RAM). No problems that I can see, but BTRFS is new and I'll keep testing.

    Ok cool! That's interesting, i had no idea there was a difference, especially with physical integrity of a system. I'll keep that in mind when i upgrade from my current laptop and put linux on my old machine. I generally like putting linux on my old machines and not use another OS, re writing and encrypting the whole hard drive makes me feel much better about discarding the machine when it eventually stops working well because of its age and out of date hardware. I don't need some one digging through the file system and finding personal and business information when it comes time to scrap it.

    When I've lost a whole computer, which has happened more times than it should, I extract things like RAM and the hard drive. Occasionally I've been able to replace the mother board in the desktop case and having those older parts in stock has reduced the cost appreciably. RAM chips in particular are harder to buy for older systems.

    By far the most frequent dead part is the spinning disk hard drive itself. They are still fairly available in both new and used parts sources. Also the newer SSD (Solid State Drive) units are being made which fit in older configuration systems. It may take some searching to find them because the older desktops are going away fast. Even older laptops are less frequently found on places like Ebay and Craigslist. Sigh, Guess I'm just old...
