Linux Diskutil Primer Tutorial
Linux (or Unix) is an operating system whose very essence revolves around files. Files are stored on Disks and Volumes and you see this in play when we analyze the diskutil command that we access in a Linux environment on a Mac laptop via the Terminal application (in Utilities). My hope for you is that you never need to know about diskutil for any other purpose than to check on a disk’s file space, name, or to partition a disk (perhaps for a dual operating system environment). My hope for you is that you never need it to repair a disk or volume, though have used it successfully myself to do this, but it is just that things have come “to a pretty pass” if you have arrived at this point, but whether you end up calling this point “Pretty Nirvana Hill” or “Pretty Death Valley” will depend on how diskutil performs.
Linux commands of interest here are:
In Windows, with command line, chkdsk has several bits of overlapping functionality.
If this was interesting you may be interested in this too.
The distinction between course-driven and immersion-driven learning is useful. A small extension to the australia.htm exercise would be a set of named map markers and a text filter: first update the visible markers on an input event, then add a collected/uncollected toggle, and finally persist only that toggle state in localStorage. That gives beginners a concrete reason to learn arrays, DOM updates and browser storage without needing PHP or MySQL first. It is also worth testing empty searches, a page reload and disabled storage separately; those are different failure cases. Disclosure: we maintain the GTA 6 interactive map. I am suggesting it as an example of a map-and-progress interface, not claiming that we used the tutorial code. Would you introduce persistence after the first working interaction, or keep the initial exercise entirely stateless?
